The MS990 Smart Antenna for satellite positioning tracks next generation GPS L2C and L5 signals, as well as GLONASS, so contractors can work at longer ranges with faster initialization times. The positioning sensor works with the GCS900 3D Grade Control System, which gives earthmoving contractors a common platform across their fleet, while allowing them to select the best option for the machine and application.
