M300 Plus GNSS Receiver

The M300 Plus GNSS Receiver uses ComNav Technology new generation GNSS engine, which makes it possible to keep track of more signals from all running satellite constellations. By using the powerful adaptive detecting and canceling technology, the M300 Plus GNSS receiver can further enhance anti-jamming capability to provide reliable GNSS data which is very critical for a reference station.
