Letters to the Editor: LightSquared Satellite Case Skimpy

July 1, 2011By

Thank you for the story “LightSquared, FCC Rebuttals Distort Record” (see www.gpsworld.com/distort). One thing worth clarifying: you state, “It appears that the purpose of Lightsquared’s satellite service is, now, to provide ancillary service in remote areas not covered by the ubiquitous primary terrestrial network, or in the event that the terrestrial network is destroyed — exactly the opposite of what the FCC authorized and the GPS industry had understood and agreed to.” read more

Expert Advice: Critical Offshore Applications of SBAS GNSS

July 1, 2011By

Precise positioning of many different kinds of vessels and other equipment depend upon satellite-based augmentation systems (SBAS) of GNSS, principally GPS and GLONASS at this time. The applications range from exploration to production and delivery of hydrocarbons to shore-based installations and navigation of very large crude carriers, or oil tankers. Decisions and recommendations are strongly needed to keep these services free from interference. read more

Expert Advice: Energy Production Concerns about LightSquared

July 1, 2011By

Dear Chairman Genachowski: The National Ocean Industries Association (NOIA), which represents approximately 270 member companies involved in outer continental shelf (OCS) energy production throughout the United States, is gravely concerned over the pending allocation of Mobile Satellite Services (MSS) spectrum to LightSquared, Inc. for terrestrial high-powered transmissions. LightSquared’s proposed transmission structure will adversely impact GPS and Inmarsat signals along our coastlines, both of which are critical to marine operations. read more

LightSquared: High-Precision Receivers Are Collateral Damage

June 21, 2011By

Originally, the LightSquared/GPS Technical Working Group’s (TWG) report was due to the FCC on June 15. LightSquared requested from the FCC, and received, a two-week extension to submit their report. Three days later, LightSquared announced they found a solution to the GPS interference problem. Their proposed solution is not good news for the high-precision GPS user community. read more

LightSquared Prospects; FCC Chair Wants Interference Cleared, Hits Back at GPS

June 14, 2011By

Concerns by government and the private sector about GPS interference from LightSquared’s proposed wholesale LTE service accelerates. Government experts just reported that interference with GPS occurred in high portions of LightSquared's spectrum bands and little in the lower spectrum. The National Space-Based PNT Advisory Board’s tests showed that some GPS receivers lost signal strength while others were fully disabled by LightSquared's signal. FCC Chairman Genachowski, under fire for granting LightSquared a conditional waiver, has reiterated that he will not permit LightSquared to begin commercial service without first resolving concerns about potential interference to GPS devices. read more

LightSquared, FCC Rebuttals Distort Record

June 14, 2011By

A claim frequently made by LightSquared spokesperson Jeff Carlisle, and recently by FCC chairman Julius Genachowski, that the GPS industry knew long ago about LightSquared’s plan for powerful terrestrial transmitters, would be a telling point — if it were true. But it is not. The verifiable fact is that the GPS industry knew about and agreed to a plan by a previous version of the company, for a different purpose, with a different business concept, and employing a completely different technological approach, one that would not have harmed GPS transmissions and disabled GPS users the way the current plan does. Calling the 2010 LightSquared plan the same as the 2003 Motient plan is running a wolf in sheep’s clothing. read more

Does Automobile as Ultimate Mobile Device Include LBS?

June 9, 2011By

As touchscreens get larger in vehicles, so does the thought that location-based services should be included. At the Telematics Detroit 2011 conference, while most industry observers say that some sort of advertising will soon be in every vehicle, not everyone is sold on having advertising flashed to drivers as they go by a business. read more
