Playing by the Rules of World Trade Law

The availability of several GNSSes promises advanced positioning, navigation, and timing services with higher availability and improved accuracy. According to a European GNSS Agency (GSA) market study, nearly 60 percent of receivers, chipsets, and modules already support at least two GNSS constellations, showing that multi-constellation is becoming a standard feature across all market segments. That development brings up questions of law and regulation that require careful handling by GNSS manufacturers, service providers, and policy makers.

First Position Fix with IRNSS

First Position Fix with IRNSS

Figure 1

The Indian Regional Navigation Satellite System (IRNSS) is an Indian Space Research Organisation (ISRO) initiative to build an independent satellite navigation system that provides precise position, velocity, and time (PVT) to users across the Indian region.

The primary objective of IRNSS is to achieve position accuracy of 20 meters (2σ) for dual-frequency users over India and the primary service area (a region extending to about 1,500 kilometers or 930 miles).

NovAtel Picked to Supply QZSS Reference Receivers

NovAtel G-III WAAS Reference Receiver

NovAtel Inc. today (June 17, 2015) announced an agreement with NEC Corporation to supply reference receiver products for use in Japan’s Quazi-Zenith Satellite System (QZSS).
 
The QZSS equipment will be based on NovAtel’s third-generation (G-III) family of reference receivers. Designed for integrity monitoring and reference measurement applications, the receivers track signals independently to provide precise code and carrier phase reference measurements as well as signal-quality measurements and other integrity monitoring metrics.

Estimating the Short-Term Stability of In-Orbit GNSS Clocks

Global navigation satellite systems provide position, velocity, and time (PVT) solutions to users whose receivers calculate position based on one-way ranging from satellites. As is well-understood, a key step in the positioning process involves a determination of the difference between the time of signal transmission identified in the satellite’s broadcast navigation message and the time of its reception by user equipment.

Judging from the variety of questions being asked at a recent EGNOS flight demonstration, the European Geostationary Navigation Overlay Service (EGNOS) remains something of a mystery for many of Europe’s leading aviation writers.

EGNOS, you say? What’s EGNOS?

“Wearable” sensors, the Internet of Things, and GNSS didn’t achieve as high a profile as they might have in the 2015 Boston Marathon held Monday (April 20, 2015). That’s because last year’s winner, Meb Keflezighi, finished eighth behind Ethiopia’s Lelisa Desisa and well off the former’s winning 2014 pace of 2:08:37.
