LabSat Releases LabSat 3 Wideband GNSS Simulator

LabSat announced the launch of the new LabSat 3 Wideband, which can record multiple signals from different constellations, simultaneously, and the company also is developing an updated version of its SatGen software.

The LabSat 3 Wideband can record GPS L1, L2 and L5 at the same time as GLONASS G1 and G2, and BeiDou B1 and B2. The company describes the lightweight unit as its most powerful to date, yet the small, easy-to-use LabSat 3 Wideband retains the one-touch recording and playback of files.

Bad Clocks, Brexit and More Happenings at the European Space Policy Conference

Speakers at last month’s 9th Annual Conference on European Space Policy in Brussels wasted no time in addressing the somewhat worrying failure of a number of Galileo onboard clocks, as revealed by European Space Agency Director General Johan-Dietrich Woerner at a press briefing earlier in January in Paris. He made clear at the time that the clock failures, while indeed troubling, had had no effect on the operational integrity of the Galileo system.

Topcon Launches MR-2 GNSS Modular Receiver System

Topcon Positioning Group has announced the launch of the MR-2, a new modular GNSS receiver system. According to the company, the system combines all current and planned constellation tracking with a comprehensive set of communication interfaces to service any precision application requiring high performance RTK (real-time kinematic) positioning and heading determination.

The MR-2 can perform as a mobile RTK base station, marine navigation receiver, mobile mapping device and as a GNSS receiver for agricultural, industrial, military, or construction applications.

State of Play in China

The BeiDou Navigation Satellite System (BDS) is China’s contribution to the world in the domain of Global Satellite Navigation System (GNSS). The BDS is being developed by the Chinese government, mainly through military departments, with key considerations for China’s national security, economic interests and social progress.

Is it possible to build a low-cost system to detect and locate a single GNSS jammer in near-real time?

Q: Is it possible to build a low-cost system to detect and locate a single GNSS jammer in near-real time?

A: GNSS jammers are an ongoing threat to the reliable use of GNSS. The problem of geolocating GNSS jammers can be addressed using a time-difference-of-arrival (TDOA) processing technique; however, this problem is quite different than geolocating jammers in other radio frequency systems. The two main differences are:

(1) No GNSS are available to use as a timing reference.
