Last week Boat/US sent out a press release that has some real urgency to it. Recreational boaters, ship operators, automobile drivers, airplane pilots, hikers, land surveyors, photographers, even search and rescue first responders, could soon fall victim to a major FCC mistake. And we all have only until July 30th to speak out.
It seems that LightSquared, a company with some big time financial clout, is trying to get the FCC to allocate frequency bandwidth to them for some 40,000 stations which would enable their expansion of land-based use of mobile satellite functions. Only problem is, the frequency spectrum is directly next to existing GPS operating frequencies.
And the FCC has already taken the first step in messing things up, by granting the company a “conditional waiver” last January.
On the good side, the FCC did commission an impact study. The results are extremely alarming. To quote: “all phases of the LightSquared deployment plan will result in widespread harmful interference to GPS signals and service and that mitigation is not possible.”
Let me add an additional nuance to this little revelation based on my own experiences with frequency spectrum interference and crosstalk. Frequency interference issues are often random; you never really know when they’re going to strike or what impact the interference will have. In this case it could mean that your boat’s chart plotter is really just kidding when it shows your position on the chart display. Lost in the woods on an extended day hike? Good luck. Flying a plane using GPS to locate an airfield? You might get to the right landing strip…..you might not. You get the idea.
After all, none of us wants to end up like the boat in the photo.
