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

Photo: Topcon 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,” says Jason Hallett, vice president of Topcon global product management. “It is an ideal component for OEMs (original equipment manufacturers) needing a custom, high-accuracy modular design for easy integration.” “The MR-2 is also designed as a ‘future-proof’ system,” Hallett says, “meaning it tracks all current and planned constellations, making it a smart investment in the expanding GNSS environment.” The unit housing is water and dust-proof and built to withstand harsh environments with superior vibration and shock tolerances, he adds. 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 MR-2 also provides a variety of communication interfaces such as Ethernet, serial, and CAN, allowing for easy integration into any application,” Hallett says. The system also offers best-in-class multipath rejection, and using Topcon Quartz Lock Loop technology can operate without disturbances in high-vibration environments.
