Topcon announces MR-1 precise heading solution

LIVERMORE, Calif., April 11, 2013 -- Topcon Positioning Systems (TPS) announces the MR-1 Heading System, an OEM GNSS solution for high-performance positioning and heading solutions.
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,” Langen said.
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 has a unique design for moving platforms and provides best-in-class multipath rejection.  This patented antenna design also offers increased resistance to near-band interference from the satellite communications systems that are commonly found in marine applications,” Langen said.
