I am using the RTK Surveyor as a archaeology documentation tool, not as a surveying tool. As such a helical antenna is attached directly to the surveyor. Sub-meter accuracy is sufficient to document most features and exact elevation rarely needed. The surveyor is often carried in a pack and the recorded track is sufficient to document the area searched. The following problems were noted in initial testing.
SMA Antenna Connector - The hole to access the SMA was not centered on the connector and it was impossible to fully tighten the SMA connector, which may lead to RF signal reduction. The bottom edge of the connector was binding against the plastic insert. A file applied to the plastic insert fixed this problem.
Power Switch - Both switches are too easy to accidentally change position. The Rover/Base mode switch can be disconnected so it will always be in Rover mode. The Power switch is a bigger problem since it is easy to accidentally turn On or Off, especially when carried in a pack. Using sticky tape to hold the switch in the correct position is a poor solution.
There needs to be someway to hold the switch in the desired position, either On or Off.
Otherwise, testing has indicated outstanding performance. The Bluetooth range outdoors has been measured in excess of 30 meters. If the power switch issue could be resolved, this would be an excellent option for archaeology students who don’t have access to multi-thousand dollar Trimble units.
