The US Department of Transportation and Defense Department on 25 March issued a strongly worded letter to the Federal Communications Commission (FCC) expressing concern over elements of an ongoing analysis on the potential effects on GPS of a newly approved broadband system.
The letter to FCC chairman Julius Genachowski from deputy DOT secretary John Porcari and deputy DOD secretary William Lynn has harsh words for the FCC.
"First, DOD and DOT were not sufficiently included in the development of the LightSquared initial work plan and its key milestones. We are concerned with this lack of inclusiveness regarding input from federal stakeholders. In particular, active engagement with DOD and DOT, the national stewards and global providers of [GPS], is essential to protect this ubiquitous defence, transportation and economic utility as the [work group] proceeds."
The letter goes on to chide FCC for not asking for consensus after seeing LightSquared's analysis or providing guidance on how different agency opinions will be brought together. The two also point out the need for their active involvement to insure national security and transportation safety. the letter reads.
The letter concludes with advise to FCC to perform a "comprehensive study of all the potential interference" issues to GPS, something not possible in the time frame set forward for the conditional approval work.
