this is going to put the special parts a certain altitude but then the satellites need to reach much higher out that you and the way we're going to do that is by uses 1st or so it's a lesser system normally it's useful for your fights as it was designed by a company that didn't really know how to do space it's an insta much cheaper than more traditional text. once supercell is done with all the assembly again and we really want to have a human errors so the way we're going to do that we're going to take a picture with this 2 cameras here and the pictures of it being take it will be compared to a reference picture and based on the do differences we'll be able to save some us have done a good job or know. with human error essentially ruled out high volume production is possible with short turnaround times. when you're doing some place of the kind it's easier to get cheaper and the record price. terms of testing we are doing

less testing so we need fewer people so it's cheaper and saw from our order of magnitude it's maybe a bit more than $100.00 but if you want to buy the satellite if you will be a roughly a 1000000 and if you want your sobriety it will be way more than. one web and also google space x. and amazon plan to offer their internet services everywhere on earth in the process getting 4000000000 people online. the london based one web has no official license from the country's airspace or serenity and sees itself on a mission to bridge the digital divide. the company's current and potential future play on tell includes banks and lines shipping companies industry disaster relief agencies and the military.

and consumers will initially be able to book the service fire local telecom providers and as already seen in the mobile phone sector the price will be lower in africa than in germany for example. mike lin's a previously worked in systems engineering for nasa and is part of the design team for the one web satellite constellation the company was the 1st among the competing consorted to receive approval from the international telecommunications union a united nations agency. and that license is absolutely mandatory for providing the service the one word system uses radio frequency spectrum in order to send information. to customers to provide this broadband internet connectivity you need spectrum that's a span of radio wave flags in order to transmit

information at high to reduce the. spectrum that you have the more data that you can provide and because you are used to these these broadband speeds of being able to stream video and send information very quickly back and forth we need a lot of spectrum in order to provide that type of service to so many people. designing a constellation of satellites in constant contact with each other and the earth is a complex undertaking. it involves a number of technical processes to function at the same time processes that have no precedence. the brain of the constellation the ground network operations center is in london it's headed by alan here at. home where my responsibility for looking after a the crown that work so we're due to call functions 1st of all we provide

situational awareness so we look for anomalies in the ground that work out where they occur we work to resolve them scripts. and secondly we do what we call a resource part and resource plan is really the crane's of how the system works which brings together the ground that work on china's spacecraft and the pay out of natural user you trace the ground stations run automatically and the fitted with 30 antennae each maintaining contact with 30 satellites. there are currently just 2 fully functional stations one in spitsbergen norway and the other on sicily to complete global coverage distributed across the planet you would need just $45.00 ground stations interconnected. very quickly and you say we're going to be scaling up country q 2 next year we're going to be out in 3 ground stations every month since

a huge ramp october. doing today today is all about testing and integration next year is all going to be about think you know cross station from. the ground stations always seek the best possible connection to the satellite that's closest to the user and can provide the best possible bandwidth. the relevant signal shifts from one satellite to another with the use the remaining place fully unaware. the one web consortium is currently ahead if rivals google space x. and amazon and by the end of 2021 it hopes to have a constellation numbering $650.00 satellites going to either way the earth's orbit is set to get a lot of traffic in the near future how will the engineers ensure that there are no collision. so something we're doing at one where is is actually enhanced seen our safety by separating each plane in the cost solution so there are multiple planes

of multiple satellites each and if they're all at the same altitude you have the sort of crossing point more salaries are zipping past each other a very high velocities so what we do is we separate those crossing points so the salaries are actually not zipping past one another when that means is we're actually in some regards we only have to manage a single plane at a time and you can apply the same principle to other cost solutions so we are maintaining. many kilometers of separation between space x. space x. is separated from. the amazon constellation and that's a very important safety detail to make sure that operators are not trying to launch an operate hundreds of thousands of satellites within the same amount of space. satellite constellations not the only inhabitants of. the sirius traffic in media

in outer space in addition to count the. disused satellites there is spent. fragments of exploded space craft and other space debris circling the planet the result is a growing orbital. now comprising 20000 objects with a diameter of 10 centimeters more joined 570-0000 smaller objects at least one centimeter in some cases and the speed at which they move makes them extremely dangerous. so if there is a question space it can be catastrophic objects in earth orbit are to plea travelling around 25000 kilometers per hour and even a small object say 10 centimeters can carry enough energy to fragment a large satellite into thousands of pieces and so if such an event occurs. now you go from one cell in one piece of debris to thousands of pieces of debris

and each of those pieces of debris might carry enough energy to again fragment a different satellite and so you know there's a sphere of a sort of chain reaction where one collision creates debris that debris strikes another satellite creating even more debris. there is still no rules on the behavior of satellite constellations whether traffic related or on safety or ethics the only stipulation is a ban on stationing weapons in earth's orbit and that the satellites have to be safely day old after 25 years from one webb has decided to let its satellites expire in the atmosphere after an operational life of just 5 years. the major space going nations are working on sophisticated nearest radar systems to prevent satellite collisions gemini's aerospace center d.l.r.

is using a missile defense system from the german military in conjunction with the famous found wolf shaft research group. radar facility outside bone in western germany is the only one in europe that can track and depict of jets in orbit up to 2 centimeters in diameter manuel nets and his colleagues have been conducting precise measurements on space there break in order to prevent the need for a vase of action by active satellites. women and how if you have an object that you are especially interested in because it is threatening to combine it with your own satellites then you can use your system to reimagine its orbit. and obtain more precise data as we in the cities of cooper

starts right gives you a better risk assessment of whether a collision is actually imminent on whether such a collision can be ruled out that. there are several collisions every day if they sit maneuvers or only needed 2 or 3 times a year. but the scientists models project a collision in orbit triggered by space debris every 5 to 10 years just how crucial this surveillance is became clear in early september 2900 when a satellite in the space x. starling constellation was approaching a weather satellites belonging to the europeans base agency. say tried and failed to persuade space x. to take evasive action but with no response from the american company the agency had to force its 400000000 euro weather satellite into a collision avoidance maneuver where the space x.

was unwilling to take action or incapable due to a lack of control over the satellites remains unclear so longer value the systems work really well and have a very high level of reliability operating the satellite constellations there's no problem but once we get into an area right in the range of 10 to 20 percent and things start to get really critical then these constellations can become a problem within themselves and between each other and that can lead to a cascade of factor where more and more space debris is created. the front to back radar facility near bowen is among the leading lights in space of a dense. material has a limited range of sight it has to be told approximately where an object is in the sky in order to conduct precise measurements. the teaser facility is immense compared to the german experimental. space to valence and tracking radar. a new elektra nicky controlled radar system that observes the near

earth zone of space within milliseconds based on semiconductor technology the radar will be the 1st in germany to track active satellites and space debris 247 also creating an orbit state catalog that helps to prevent collisions. clown is in charge of gemini space situational awareness and which will work together with data collection he's seriously concerned about the satellite constellations currently being assembled. there could be the problem of the electric drive systems in the one website allowed to do not allow hard delta vees or speed increases. to. plan is to deploy the flutes in an orbit of around 500 kilometers and then slowly

push them to 1200 kilometers through the most contaminated belt and then bring them back down at the end of their lifetime. when. it's a problem similar to sending a family of snails across a major road during rush hour. for reading. there's a major risk of collision not least because the electric propulsion systems do not give the satellites much scope for evasive action. the data from the t.v. system and from gets a collated it gemini's stay situational awareness and. the dutch. the german armed forces and the german air a space center work together at the nato communications and information agency unit . radar systems can only track the near. and not geostationary orbit

so the center also uses telescopes to surveil satellites the to hire out and there are already concerns on the ground over the 1st satellites launched by space x.'s starlink constellation. was huge so i took by the what i saw from the launch of the past 60 star link satellites is that the prognosis is relatively high. and that can lead to interference or to observations or near. normal. the problem feared by astronomers growing population up to 10 years or 1000 so many satellites in the low and medium. will reflect the sun's rays on to. and in those areas of observation telescope coverage will be compromised. not surprisingly some of the traffic in the low earth orbit is from military

sources the relatively close range of 502800 kilometer is a convenient one thing gathering meteorological and geological data and the studying nowhere else in gemini did the armed forces and the civilian german air space center work so closely together could represent a we can see the one when constellation with 6 satellites launched today all on one orbit. this is the stunning constellation with 10 times the number of satellites spread across different overtop claims of this constellation is likewise set to grow significantly in the future. they are totally sure. anymore if you were told of a large number of electrically powered satellites being introduced into critical orbit hearts will definitely post questions. in the final phase of the satellites deployment this will also present a bigger challenges for global surveillance systems than is the case with the

current population and all that. so we have to prepare accordingly and continue to expand our capabilities of a cloud what else for. the importance of protecting critical infrastructure such as whether g.p.s. and observation satellites was highlighted in march $2900.00 the indian military shut down one of the country's weather satellites in order to demonstrate its strategic space capabilities the satellite broke up into 6 and a half 1000 pieces of debris which then spread around the globe or to speed of 35000 kilometers per hour. interesting thing in this area is not so much the mass of dead briana's that stay on the rich. or is the pants moved by kinetic energy. of course pose

a threat to others. since you can. china has also demonstrated its ability to destroy a critical infrastructure in low earth orbit. ton in south korea is just a 2 hour car drive from the border to north korea everyone here is aware of the threat from the north's missile system and it's here that one webb is working with intel and south korean specialists in maritime satellite communications and telling and is making the satellite antennae for the ground stations and use the terminals that can pick up and relay the signals from the satellite constellation at any point on a us. the koreans the chosen due to their experience in maritime communications where the transmitter and receiver of signals

a both moving the idea is to adapt that technology for internet access in self driving cars permanent connectivity will become increasingly important. steve china and kevin other visionary minds behind intelli in the mega country or is still challenge but we have all the solution now so cio is fixed so far i think a vessel is moving so that means i should. also maintain a tractor trailer. we are developing using now but limbaugh visually. is movie so that means all we have to more i go by ship or by satellite there means. accuracy so even though the worst cases we have to bury. accurate track the video and you can maintain the

connection so there could be our challenger for your future so we'll try to overcall. rotating parabolic antennae at the cutting edge of current technology but a few years from now there might well be new antennae available based on semiconductor technology this is a company. with a couple of. years of your future but this one is normally chemical body is right or we can put here where there is a some electronic circuit inside electronic circuit to real. traffic itself so it's kind of on the mechanical. motion and then a very accurate track and also very small. whether by sea land the idea is to ensure easy connectivity for people using all means of transportation in addition to those who were stationary.

this facility near seoul tests radio communications with objects in the earth's orbit. a group of engineers headed by physicists now feigns spent several months focusing on one specific task proving beyond doubt that an internet connection can be established on 90 days in a row via satellite constellation that test results would determine whether one website writes to transmitted the frequency spectrum approved by the international telecommunications union would be confirmed it's a milestone the team eventually reached in 2019 satellites were launched in february of this year and i want to show the proof of concept that it works so we want to be able to send signals up to the satellite but down again and prove that we can send traffic very high speed. and therefore realize some of these services

you know high speed broadband services that we want to offer the world so this is a perfect testing ground we've got regulatory clearance here to do transmissions and receptions. could a system initially comprising just 6 satellites in orbit streamed internet video content from germany now bain's and his team were also eager to see how the experiment pans out. what we'll be doing is where we're going to visit the earth shall rise up and getting content from there over to our modems on to the terminals themselves up to the satellites back down again i know all the acknowledgments coming back to across the internet so we can keep on streaming just here we just got 3 more minutes and then the satellites will be coming out over its satellite flies it takes about 3 minutes and then the next next.

1010 seconds. every day. we're now live streaming video from the city you have to. travel. the work briefly of the quality of the signal wasn't good enough so it lost lost connection but. we try and we're still in testing we're testing the circuit so optimizing the system to get better and better performance better latency. improved quality of video all the stuff lives ok well thanks everybody for joe thank. providing sufficient bandwidth for streaming videos in full h.d. will require the launch and deployment of far more satellites and more ground stations. over in the

united states one where has a 2nd ground station not far from washington d.c. . the constellation satellites can be controlled from here and from headquarters in london. daria corinne is responsible for coordinating the constellations flight maneuvers she and colleague ny richie control individual satellites. here the 2 experts are conducting extensive tests connected to automatic control routines. it's a system that i want to trust but at the same time as a human i want to make sure i'm checking all of all of my checks and balances making sure that everything is ok with the tally before we proceed to the next step because again this isn't a simulation we have to take our time and we have to be as humanly perfect as

possible how many controllers will be required to pilot a mega constellation of several 100 satellites this is well artificial intelligence will come in to assist the human operators i believe we're going to be having one controller for about 20. 30 so it's maybe even more we're trying to automate our system so that one person can handle as many satellites that is needed within our crews because i mean like you said we're not going to have a one to one ratio and we need to learn to automate our system so that when we see issues on board if our pilots can't do it manually then automatically our system should be able to handle it it's kind of a walk before you run type of i guess philosophy so instead of having so many satellites up at 1st we deployed you know 6 and then we could spend a significant amount of time kind of getting to know them i can make a new friend basically just deciding you know this satellite is capable of this and

it's not capable of this and ball i kind of adapt to the constellation as it grows to because of our ability to understand the vehicles for months we've you know since last for about 6 months now and we have gotten a good idea of the types of tools that will need in order to use you know sustain a mega consolation and in addition to the technical challenges there are also no end of regulation to reopen stickles to overcome it's all right. kelly into a team of trying to convince more than 200 different countries and territories to grant one web commission to provide services. every person in the world wants access to information and entertainment and they may define that differently and their country may be concerned about what access they have but even a country like north korea wants their people to have access to certain kinds of

information right and so every country in the world wants their people connected they may want to control the way they're connected they may have concerns about data protection or security but they want their people connected and so even north korea even cuba. even india china russia they're all interested in conic to vittie connectivity is the key to the future. internet access in north korea china and russia is regulated differently than in germany what surprised the company was how more democratic nations also tend to demand an emergency off switch before giving approval to internet access via satellite constellation you know what even the united states asked for an off switch. every country wants a little control over the traffic in its country and one of the things they say basically is if you cause interference usually you'll need to be turned off and you say of course the ideas i'm never going to cause interference it will go back to

the coordination with the other satellite systems i don't want to have to turn off so i'm going to make darn sure that i'm not interfering into anything. one web and its rival google space x. a comically neck and neck in this new space race with amazon lagging some distance behind with the high speed internet from blow us all but it will actually be commercially available by the end of 2021 is still hard to say. south korea has the fastest mobile internet on the planet and practically everyone here has high speed connectivity via to rest real all mobile networks. and it's here that now things in his colleagues are working towards a few chill where every person on earth could have fast internet via satellite provided that governments allow it.
