The OC Register reported yesterday that the Federal Railroad Administration has granted Caltrans with $55-million to construct, among other things, a third rail to connect Fullerton and Commerce.
The Register's report also includes an important but completely misunderstood issue.
And $13.5 million will fund a global-positioning-based system for much of the line between Moorpark and San Onofre. Also called Positive Train Control, the system prevents collisions and derailments. The Federal Rail Safety Improvement Act makes the system mandatory by 2015.
“The implementation of the Positive Train Control will improve safety for our passengers,” said Laura Scheper, a spokeswoman for the Orange County Transportation Authority, which oversees Metrolink service in the county.
So what's the problem? A new company known as LightSquared. Their use of a nearly identical frequency as that used by global positioning systems (GPS) causes GPS receivers to fail.
I have expressed serious concern regarding the Federal Communications Commission (FCC) granting LightSquared, LLC conditional approval to build a nationwide 4G-LTE wireless broadband network (FCC File No. SAT-MOD-20101118-00239). Early testing by GPS technology leaders, Garmin and Trimble Navigation, demonstrated that LightSquared’s technology would likely interfere with Global Positioning System (GPS) receivers, degrading their performance in the best case scenario and completely jamming GPS receivers in the worst case scenario.
The Department of Defense, FAA, DHS, NASA, DOI, DOT, DOC, and the Professional Land Surveying and Engineering professions, have all expressed serious reservations in regards to this plan by LightSquared, LLC to build 40,000 ground stations in the U.S. that could cause widespread interference to GPS signals.
The National Marine Manufactures Association said in a letter to the FCC that "they are especially concerned with the apparent lack of concern shown in the Technical Working Group report to the effect of the LightSquared proposal on existing devices." The July 29, 2011 letter goes onto to say that "it is notable that the testing that was done by the Technical Working Group did not include recreational marine applications."
The result of having GPS-guided trains AND LightSquared means a nearly certain disaster is on the horizon!
This network of ground stations will transmit signals within the L-band frequency immediately adjacent to the GPS L1 frequency at more than one billion times the strength of the low-power GPS signal from space! Furthermore, each mobile phone using LightSquared’s wireless service would potentially become a portable GPS jamming device by jamming GPS receivers in its immediate vicinity.
The result of having GPS-guided trains AND LightSquared means a nearly certain disaster is on the horizon!
LightSquared has openly admitted to the interference after conducting their own tests! "Initial tests of LightSquared’s terrestrial base stations, however, have shown that these transmissions can cause interference issues for GPS receivers."
I wrote a letter to the FCC and Congressman Royce and have not heard back from either. I'm not holding my breath...
Telecommunications lobbyists acknowledge that "it is likely there will be interference issues that will need to be solved".
