Chairman, the National Space‐based Position Navigation and Timing Advisory Board (7/5/17)

“Extensive government testing in 2011 and in 2016, clearly shows that both proposals cause definitive harmful interference to many classes of GPS receivers.”

“We confirmed that the current proposal is fundamentally the same as the [Lightsquared] proposal tested in 2011.”

“[The initial round of The Department of Transportation’s ABC Assessment] shows that harm can occur to precision GPS users at a half mile from each of the several thousand ground transmitter sites planned under the new proposal, even at the reduced (by a factor of 100 from that of the original proposal) 15.8 Watt (W) power level that the new proposal claims.”
