High-precision GNSS Receivers

The benefits and availability of new signals and systems
What will the new GNSS signals bring to the user of high-precision receivers? This article provides a brief overview of what users can expect from GNSS systems that are currently in the modernisation/development stage, looking at new signals and emerging techniques including coverage of GNSS developments such as GPS, Galileo, GLONASS and Compass/Beidou. In view of the planned timeframe, what we can do to improve the robustness of our receivers with a special focus on interference and the upcoming solar maximum? The use of high-precision GPS for surveying applications has increased dramatically over the last decade. GPS receivers can provide... (read more)

Four times GNSS

A Worldwide Race
The Munich Satellite Navigation Summit opened during the first week in March 2009 with a plenary session entitled ‘The Worldwide Race in GNSS’ and closed with a panel discussion on the subject of ‘competition among the Big Four’. Although several speakers did their best to convince attendees that there was no race or competition, it is obvious that four systems serving the same market will be involved in a race for the best technical solutions and engage in fierce competition. If it is indeed a race/competition, let us have a look at the score so far. GPS Since 1978 this... (read more)

Integrating GNSS and INS

GNSS provides accurate positional information with relatively low integrity, while INS offers position and attitude information subject to drift but with relatively high integrity. Integrating the two provides reliable and accurate information on position and attitude of vehicles on land, at sea, in the air and in space. Integrated GNSS/INS: I know what it is, I know what it does, but how does it work? All sensor data such as aerial imagery acquired from an airborne platform needs to be geo-referenced to be of further use. In treating the subject of exterior orientation we here focus on aerial digital cameras,... (read more)

Hemisphere GNSS Announces New Survey-grade GNSS Antennas

Hemisphere has launched two low-profile, multipurpose antennas that will arguably exceed expectations in all GNSS applications. With innovative filtering patterns and precise attention paid to mitigation of multipath and interference, the A25 and A45 antennas complement all GNSS products, from L1 GPS to multi-frequency, multi-constellation, the company announced. The A25 and A45 have been designed to support millimetre accuracy for land and marine applications. Both antennas support present and future GNSS signals, including GPS, GLONASS, BeiDou, QZSS, and Galileo. The A25 supports the previously mentioned signals at a single-frequency level, while the A45 supports these signals at a multi-frequency level.... (read more)

Sun Flares May Disrupt GNSS

Sun flares, magnetic eruptions from the sun, may have influence on GNSS systems these days as they can make measurements less accurate up to 10m. Region 1158 produced the largest xray flare in more than 4 years, an X2.2, earlier today at 0156 UTC reaching the R3 (Strong) NOAA Scale level.     A Coronal Mass Ejection occurred too, lined up in the queue with the CME from Sunday's event and possibly another associated with the R1 Radio Blackout yesterday. Enhanced solar wind is expected to begin later today, and become increasingly disturbed with the CME arrival(s) about 17 February.... (read more)
