The lab have two high resolution GNSS receivers. The newest is a Trimble GeoXR 6000 from 2014 and the second is a TopCon GRS-1 from 2010. Both uses RTK (Real Time Kinematic) and connects to Swepos using either Telia cellular network or through a WLAN connection with a Net1-modem. Both these devices can measure a point in a few seconds with centimeter resolution, but it needs clear vision to the satellites.
Here are user instructions for the devices:
- Trimble GeoXR 6000
- TopCon GRS-1 (e-mail us if you need a copy, will be published shortly)
