Setting up the Receiver 5
With Moving Baseline RTK, the reference receiver broadcasts Compact Measurement
Record (CMR) data every epoch, while the rover receiver performs a synchronized
baseline solution at 10 Hz. The resultant baseline solution has centimeter-level
accuracy. To increase the accuracy of the absolute location of the two antennas, the
Moving Reference receiver can use differential corrections from a static source, such as
a shore-based reference station.
Mounting a pair of SPSx50 GPS receivers
To obtain a position and heading solution, you need to connect two SPSx50 receivers
to make one compact unit. A mounting bracket and interconnecting cable is supplied
with the SPS550H receiver. Set up the receivers, antennas, and cables as shown in
Figure 5.2.
