GSA Issues Second GNSS Market Report: 1.1 Billion Units by 2020

The European GNSS Agency (GSA) has published its second GNSS market report, including a special focus on maritime and surveying application markets and refining its projections of unit and sales revenue volumes through 2020.

According to the new GSA report, the worldwide GNSS market is growing rapidly with total market size expected to increase at an average of 13 percent per year until 2016. At that point, increasing market saturation, price erosion, and platform convergence will reduce the growth rate.

Thales Plans Next Steps in GNSS Technology Evolution

Thales TOPSTAR 100 receiver

French manufacturer Thales, the only non-U.S. company to offer GPS SAASM (Selective Availability Anti-Spoofing Module) receivers, is working on next-generation receivers for commercial aviation and military markets that will incorporate new signals and multiple GNSS systems.

Since the late 1990s, the company has delivered between 8,000 and 10,000 avionics installations in military and civil domains, according to Pierre Bouniol, GNSS Products Department manager, including multi-mode GPS receivers in stand-alone and enclosure configurations.

1. GROWTH SPURT
California/Nevada, USA
√ The age of the Sierra Nevada mountains — home of Yosemite Valley and Lake Tahoe — is puzzling to geodesists. Integrating GPS and inSAR, Universities of Nevada and Glasgow teams studied the area’s uplift and found that it is growing by 1 to 2 millimeters per year. The verdict? The entire range could have arisen in less than 3 million years.

How do GNSS-derived heights differ from other height systems?
May 24, 2012

How do GNSS-derived heights differ from other height systems?

FIGURE 2: Example of a national geoid (upper diagram) and a correction surface for the transformation from the new orthometric height system to the old height system (lower diagram). Country is Switzerland. Geoid undulations range from 45 to 55 meters in ETRS89 and from -5 to +5 meters in the national System CH1903+. Lower diagram: Correction surface to transform from the new orthometric height system (LHN95) to the old height system LN02 with corrections from -0.10 to 0.55 meters.

Q: How do GNSS-derived heights differ from other height systems?

A: Height estimation using GNSS always seems to be trickier than horizontal coordinate estimation.

Why?

On the one hand, the GNSS technique has error sources that are more critical in the vertical direction. Height estimates are weaker because of a combination of satellite geometry, the presence of strong correlations to other parameters, such as atmospheric delays, and the antenna phase center model applied during data analysis.
