Appendix J - RS500
Introduction
The RS500 receiver has been de-
signed specifically for use as a
reference station.
The RS500 uses the same housing
and meets the same environmental
specifications as the SR5xx sensors,
which are detailed in Appendix A.
Generally, the RS500 operates in the
same manner as the SR530, but is
designed to operate for specific
reference station applications using
remote control software, i.e. Leica
Geosystems ControlStation™ soft-
ware.
It supports internal logging of GPS
raw data, but can also log data from
specific external devices approved by
Leica Geosystems. Both GPS raw
data and external sensor data can be
directly output to an external remote
control software package.
With a radio modem attached, the
receiver can be used to transmit data
for RTK operations using proprietary
as well as standard RTCM, CMR and
CMR+ formats. The RS500 cannot
receive Reference Station broadcasts
and therefore cannot be used as a
Real-Time rover receiver.
The receiver and measurement
performance is the same as with the
SR530. The RS500 tracks the L1 C/A
code and L2 P-code to reconstruct
the carrier phase. When Anti-Spoof-
ing (A-S) is activated, the receiver
switches to a patented P-code aided
tracking technique that provides full
L2 carrier measurements and L2
pseudoranges.
Standard Features
The RS500 includes the following
standard features, which are not
available in the SR5xx sensor types:
One PPS Output port.
Two Event Input ports.
Ring Buffer logging.
Support for external sensors (Meteo/
Tilt).
Data Storage
The RS500 supports all standard
Leica Geosystems PCMCIA card
types. The internal memory option
may be installed as well. This enables
data to be stored internally for post-
processing.
