LightSquared: 1, High-Precision GPS: 0

July 14, 2011By

At stake is the high-precision GPS industry as we know it. If LightSquared's current proposal is approved by the FCC, it will render tens of thousands, and possibly hundreds of thousands of GPS receivers obsolete starting as early as next year. The FCC is accepting public comments until July 30 and replies to those comments until August 15. After the public comment period is closed, the FCC can render a decision at any time.

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.

Q&A from L5 and LightSquared Webinars

May 5, 2011By

In late March, I conducted a webinar titled "A Closer Look at L5: The Future of High-Precision GNSS," in which I discussed the impact that the new GPS L5 signal/frequency may have on high-precision users. Then, in April I was part of a discussion panel-format webinar titled "LightSquared: Our Story So Far." Many questions and comments arose from both webinars, and I'll attempt to address those in this column. read more

LightSquared Saga, and Recent Solar Activity

March 2, 2011By

This week I'm following up on my article from a couple of weeks ago about the potential effects of LightSquared's plans. As a user of high-precision GPS receivers (particularly GPS L1 sub-meter, but also dual-frequency), you should be particularly concerned about this issue. I'll tell you why. Also, I have a note on recent the solar activity. read more
