Sen. Chuck Grassley, R-Iowa, wants global positioning manufacturers to disclose their correspondence with the Federal Communications Commission over LightSquared's plan to launch a nationwide wireless network.
Grassley has criticized the FCC and LightSquared for a lack of transparency as the agency considers LightSquared's plans, which have been shown to interfere with GPS devices. In October Grassley sought similar documents from LightSquared, which began releasing some information in December.
This latest request to the GPS companies is in response to complaints from LightSquared that Grassley was singling it out. But Grassley said the focus remains on LightSquared.
"My focus on this investigation has not changed, and I am aware of no allegations concerning the communications of the GPS community with the FCC about the LightSquared waiver," he said in letters to Garmin, Trimble and John Deere.
Grassley is blocking Senate confirmation of two nominees to the FCC after the agency and LightSquared declined to provide their communications with each other. The Senate Commerce Committee approved the nominees last month.
Trimble, for one, says it will work to comply with Grassley's request.
"Trimble's communications with government decision-makers are entirely in line with these concerns, and will provide Senator Grassley a more complete picture of the information that was made available to these decision makers," said Trimble vice President Jim Kirkland.
