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.

“The MR-2 delivers navigation support for a wide-range of applications — it is an ideal component for OEMs (original equipment manufacturers) needing a custom, high-accuracy modular design for easy integration,” said Jason Hallett, vice president of Topcon global product management. “Its housing is water and dustproof and is built to withstand harsh environments with superior vibration and shock tolerances. The MR-2 is also designed as a ‘future-proof’ system — meaning it tracks all current and planned constellations — making it a smart investment in the expanding GNSS environment.”

Using Topcon HD2 heading determination technology, the MR-2’s dual antennas compute high-performance heading and inclination determination alongside the RTK positioning engine for precise navigation and guidance applications.

The modular GNSS receiver system tracks signals for GPS, GLONASS, Galileo, BeiDou, and SBAS Corrections. Other system specifications include the following: 226 channels with universal tracking; an update/output rate up to 100 hertz (20 hertz standard); and a power consumption of 10 watts @ 9-36 VDC. The MR-2 weighs 0.95 kilograms and features dimensions of 172 millimeters (width) x 166 millimeters (depth) x 49 millimeters (height).

“The MR-2 also provides a variety of communication interfaces such as Ethernet, serial, and CAN, allowing for easy integration into any application,” said Hallett.

The system also offers multipath rejection and using Topcon Quartz Lock Loop™ technology can operate without disturbances in high vibration environments, according to the company.
