On Thursday LightSquared finally with which GPS company it partnered to create a filtering solution that it suggests will solve issue with GPS interference (press release). The company? JAVAD. The Amercian Surveyor interviewed JAVAD at the Survey and Engineering Summit (videos). LightSquared offers an interview from Goldman Sachs 20th Annual Communacopia Conference that explains the solution here.
The Save our GPS Coalition made this statement in response:
LightSquared has, as usual, oversimplified and greatly overstated the significance of the claims of a single vendor to have ‘solved’ the interference issue. There have been many vendor claims that have not proven out in rigorous tests and the demanding tests of marketplace acceptance. Moreover, this is not a one-size-fits-all situation and a few prototypes does not a solution make. The estimated 750,000 to 1 million high-precision GPS receivers now in use in the United States vary widely: there are hundreds of different high-precision devices used in performing thousands of different tasks. High-precision GPS supports a wide variety of uses, including agriculture, construction, aviation, surveying and many scientific and safety-of-life applications.
LightSquared also ignores that fact that availability of new products, even if confirmed, does not address this very large existing base of equipment. If and when solutions are available, LightSquared must accept responsibility for paying to replace the existing base of existing equipment with new products.
In any case, this is not an issue that can be solved with a LightSquared press release. As the FCC and NTIA recently recognized, more testing is necessary to evaluate interference impacts under LightSquared’s latest technical proposals. We welcome the participation of Javad in those tests.
