Spectra Precision SP90m - Dual-Relative RTK

Dual-Relative RTK
To configure the receiver as a Dual Relative RTK rover, use the
Web Server as follows:
• Go to Receiver > Position > Rover Setup.
• Set Processing Mode to Dual Relative RTK.
• Select how the corrections are being transmitted to the
receiver by setting Input Mode accordingly.
If you choose Automatic, the receiver will find by itself
which of its ports are used to acquire corrections.
If you choose Manual, you need to specify each of the two
ports. The “BRV-1” line will define the port routing the
corrections from a moving base allowing the receiver to
compute the vector to the primary antenna, whereas the
“BRV-2” line will define the port routing the corrections
from a moving base allowing the receiver to compute the
vector to the secondary antenna.
NOTE: The same set of corrections from the same moving
base, hence the same port, can be used for both antennas.
• Additionally, in the Other Settings section, you may change
the primary GNSS system used (GPS is the default
selection), limit the level of position accuracy to less than
what the receiver can actually achieve in this case.
Typically you will choose RTK Position to match to the
selected operating mode.
