mr. kirkwood what is trimble navigation and what is the coalition to save our gps?>> guest: sure, peter. triple navigation is the leading manufacturer of gps equipment for commercial industrial use that we focus on high-end industrial applications like agriculture, construction, surveys and you name it. the coalition to save her gps was founded after an initial fcc decision last january granted a waiver to lightsquared to proceed with its buildout of its network and our mission is to educate policymakers on the gps industry and the implications of that proposal, and we have been very active on that. >> host: jim kirkland last week on "the communicators" we talked with sanjiv ahuja the chairman and ceo of lightsquared and essentially what he told us is he understood the concerns and what they have done is, they have moved their spectrum usage as far away as possible within their spectrum from gps units to mitigate the danger. >> guest: sure. so, the issue here is that the technical evidence so far from the fcc still shows interference even from these modified plants
