Basically all satellite-based positioning methods work according to an identical principle: a receiver receives satellite signals and calculates its own current position. However, different systems may vary in the form of information transmission. For example, GPS satellites transmit on one frequency band, while GLONASS satellites transmit the same information over two frequency bands. This makes it possible for receiver to compensate the signal delays, that occurs in the Earth's ionosphere, and calculate the distance to the satellite accurately. The signal from Galileo satellites have even higher precision. A particular feature of this device is that it combines the advantages of different systems. A GNSS receiver has access to much larger satellite information, as a GPS receiver. GM-3N provides superior navigation performance under dynamic conditions in areas with limited sky view like urban canyons and in complicated environment.

Delivery: GM-3N GNSS receiver with USB cable in plastic bag (no box), GPSview configuration software and driver - per download.
