Spectra Precision’s newest technology, the SP80 GNSS receiver, is out in the field and getting a lot of attention. It can be used as an RTK network rover, an RTK base and rover, and also for post-processing.
The SP80 tracks six constellations: GPS, GLONASS, Galileo, BeiDou, QZSS and SBAS. The SP80 is unique because it will fully fix on any of five of these constellations or a mix. So you can fix GPS only, GLONASS only, or BeiDou only. Time to fix is 50% better than the Promark 800, about 2 seconds for a 20-km baseline.
