A Pro XRS System
A.5.2 RTCM Input
You must also be using a base station which is logging or transmitting
(in RTCM messages) synchronized measurements, and which is
equipped with an EVEREST capable Pro XR, Pro XRS, 4600LS, Site
Surveyor 4400, GPS Total Station 4700, GPS Total Station 4800 or
Series 4000 GPS receiver. Your roving receivers must be within 500
km of your base station.
Note – Using receivers without the appropriate EVEREST firmware
installed results in a degradation in accuracy.
The Pro XRS receiver supports RTCM Version 2 input. Connect your
RTCM link directly to the cable labeled ‘RTCM’.
The Pro XRS receiver with integrated Beacon/GPS antenna receives
and demodulates MSK DGPS radiobeacon signals from radiobeacon
transmission stations (for example, USCG). No special configuration
is required to receive these signals.
The Pro XRS receiver extends the use of real-time differential
corrections to many areas where other sources of real-time differential
corrections (for example, radiobeacons) are currently unavailable. The
satellite differential receiver requires a subscription to a differential
service and provides multiple vendor support.
A built-in virtual reference station (VRS) permits the satellite
corrections to be uniformly associated with the increasing distance
from the fixed reference stations. For more information on the
Pro XRS GPS receiver, refer to the Pro XR/XRS Receiver Operation
Manual.
