Topcon Positioning Systems has released the MR-1 Heading System, an OEM GNSS solution for high-performance positioning and heading.

Using the MR-1 receiver and Topcon’s MG-A8 antenna, the system provides “centimeter-accurate RTK positioning and better than 1/10 of a degree heading accuracy in challenging environments,” said Doug Langen, TPS GNSS product manager. “The rugged MR-1 receiver is water and dustproof and operates at a robust operational temperature range of -40°C to 75°C.”

When combined with Topcon’s Quartz Lock Loop technology, the MR-1 offers continuous operation during “extreme vibration and shock, typical of intense dynamic environments,” he said.

The MG-A8 antenna of the MR-1 Heading System is designed for moving platforms and provides multipath rejection. It also offers increased resistance to near-band interference from satellite communications systems commonly found in marine applications.
