GR-1: Ground Speed Radar
Meet the Ainstein GR-1—a high-precision ground speed radar engineered to deliver accurate, slip-free speed and distance measurements for off-road vehicles and heavy equipment. Using advanced mmWave radar technology, the GR-1 measures ground speed from ±0.5 to ±50 mph and distances up to 110 meters, maintaining reliable performance across loose soil, mud, flooded terrain, and challenging weather conditions without the inaccuracies or mechanical wear of traditional wheel-speed sensors. With native CAN bus (SAE J1939), flexible digital outputs, and rugged IP67/IP69K protection, the GR-1 is built for demanding applications including wheel loaders, heavy machinery, ground-speed monitoring, and backup warning systems.
