Spirent Launches Data Sets of World City Environments to Aid GNSS Receiver Testing

Spirent Communications has launched of a subscription service for live GNSS (GPS, GLONASS, and QZSS) environmental-capture data set samples, recorded at major locations worldwide, in challenging urban and suburban conditions.

The data sets are designed for use with the company’s GSS6400 GNSS Record and Playback test System. They encompass a variety of recorded scenarios ranging from drive-through multi-level roads, tunnels, and car parks to drive-throughs in downtown areas with high-rise buildings.

LightSquared Petitions FCC to Confirm Company's Rights to GPS Spectrum

LightSquared today (December 21, 2011) asked the Federal Communications Commission (FCC) to confirm the company’s right to use spectrum licensed to it and that commercial GPS manufacturers have no right to interference protection from LightSquared’s proposed wireless broadband network.

Latest Tests Confirm LightSquared Interference to GPS Navigation Equipment

Tests of LightSquared’s proposed wireless broadband transmissions in the lower LightSquared band (1526–1536 MHz) caused harmful interference to a majority of personal/general navigation GPS receivers.

Return to main article: "True3D HUD Wins Global SatNav Competition"

Many technologies are created before their best applications are even thought about. This leads to a business phenomenon known as “technology push” in contrast to “consumer pull.” The True3D Volumetric HUD technology did not share this path.

GPS Timing Used in Experiment to Measure ‘Faster Than Light’ Particles

No sooner had GPS positioning helped validate key aspects of Einstein’s general theory of relativity in the Gravity Probe-B program than GPS timing has been cited as helping bring his special theory of relativity into doubt.

At issue is the so-called OPERA (Oscillation Project with Emulsion-tRacking Apparatus) experiment, inaugurated in 2006 with the main goal of studying the rare transformation (oscillation) of muon neutrinos into tau neutrinos.

Oh No! Not LightSquared Again!


Please. Please. Please. 

Can we please talk about something besides LightSquared?

Not yet? You mean, they are still here?

And we have so many other GNSS-related topics that deserve comment: 

Some peculiar cuts in civil GPS funds and GPS III budgets being proposed by congressional committees. 

A re-examination — aka analysis of alternatives — of GPS and PNT options in general. Space weather and an impending solar max. Warrantless GPS-aided tracking before the Supreme Court.

LightSquared: Who Pays for GPS Receiver Fixes Yet to be Devised?

With more testing on the horizon and a potentially alarming homeland security report about to be released, LightSquared’s efforts to begin work on its proposed wireless broadband service are stuck in the procedural mud.

The delays, which are never good for a commercial company, are piling up just as the firm’s coffers are thinning and need to be replenished with a new round of fund raising.
