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.

Spirent Security Experts Predict Greater Risk to GNSS this Year

Spirent Communications plc’s annual security forecast warns of the increased likelihood of disruptions this year to a wide variety of civil and military applications relying on global navigation satellite systems — GPS, GLONASS, Galileo, and BeiDou.

Criminal Liability Found in 2010 Explosion of Proton/GLONASS Satellites

Back in December of 2010, Inside GNSS reported that the loss of three GLONASS-M satellites in space resulted from a series of mistakes made by the Russian Energia rocket corporation. Now, more than six years later, Russian prosecutors have wrapped up a criminal case against four employees of Energia allegedly complicit in the crash of the Proton booster with three GLONASS satellites, and they’ve sent the case files to a court of law.

ITM/PTTI addresses advances in GNSS technology, precise time

Another informative joint Institute of Navigation (ION) International Technical Meeting and Precise Time/Time Interval Meeting is in the books and attendees of the event this week in Monterey, California had the opportunity to learn and share ideas on a wide array of topics and technologies.

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.

Interference Localization from Space

Working Papers explore the technical and scientific themes that underpin GNSS programs and applications. This regular column is coordinated by Prof. Dr.-Ing. Günter Hein, head of Europe's Galileo Operations and Evolution.

Aireon’s First Launch for Space-Based ADS-B Network a Success

A January 14 launch of 10 Iridium NEXT satellites will help implement a space-based automatic dependent surveillance–broadcast (ADS-B) developed by Aireon, in partnership with leading Air Navigation Service Providers (ANSPs) from around the world, and designed to provide real-time GNSS tracking of aircraft over oceanic regions.
