mode to collect data. So, while moving, the Rover is in kinematic mode, and while collecting
data, the Rover is in static mode.
1. Set up the Rover at an unknown point and press power. Allow the Rover to collect static
data for two to ten minutes. The REC LED will be yellow.
2. Check the SAT light for satellites tracked.
3. When finished, press the FN button for less than 1 second to assign the Rover to
kinematic.
4. Move the Rover to the next location (survey point), and press the FN button for less than a
second to collect the data in static mode for two to ten minutes.
5. Repeat steps five and six until all points have been surveyed. The occupation time for the
points depends on the same factors as for the static survey method.
6. When finished, press the FN button for one to five seconds to stop logging data. Turn off
the Rover if needed. This method of GNSS survey allows the operator to reduce the point
occupation time, thus permitting field crews to survey many more points compared to the
other methods available.
4.5. Real Time Kinematic Surveying
With RTK surveying, as with kinematic surveying described above, one receiver serves as the
reference station and conducts observations with its antenna affixed to a stationary tripod or some
other device. The other receiver functions as a rover and conducts observations (using an antenna)
affixed to a mobile pole and moved to observation points.
Unlike post-processed kinematic surveys, RTK surveys utilize a communications link between
the Base and Rover. Using a radio modem link, the Base receiver transmits its measurement and
location data to the Rover receiver. The Rover, based on the transmitted data and its own
observation data, immediately conducts a baseline analysis and outputs the results. For specific
settings used in RTK surveys, see “Configuring the Internal/External UHF Modem/GSM
Module” on page 44 and “Configuring the Receiver” on page 56.
Usually, the receiver will start to output the coordinates of the antenna’s phase center along with
the solution type within 10–30 seconds. However, UHF radios and GSM phones may take as long
as 60 seconds to synchronize.
The geodetic coordinates displayed on the Location tab are always computed in WGS84 and have
four solution types.
• Standalone – where the receiver computes 3D coordinates in autonomous mode without
using differential corrections.
