System description
GPS Receiver
The GPS Receiver receives the GPS
signal from the NAVSTAR satellites
and calculates a range to all visible
satellites.
There are various types of Receivers
available:
SR510 - 12 L1 channels,
code and phase
SR520 - 12 L1, 12 L2 channels,
code and phase
SR530 - 12 L1, 12 L2 channels,
code and phase, RTK capable
MC500 - 12 L1, 12 L2 channels,
code and phase, RTK capable
RS500 - 12 L1, 12 L2 channels,
code and phase
System description
The SR510 utilises the AT501
Antenna. The SR520, SR530 and
GS50+ typically utilise the AT502
Antenna but may also use the AT503
and AT504 Antennas. The MC500
utilises the AT502 Antenna but may
also use the AT503 and AT504
Antennas for GPS Reference Station
use. The RS500 utilises the AT503 or
AT504 Antennas but may also use the
AT502 Antenna. The GS50 may use
either the AT501, RTB or RTS
Antennas.
See section 8 for technical
specifications.
The SR520, SR530, MC500
and RS500 Receivers use
the GPS P-code signal, which by
U.S. policy is liable to be switched off
without notice. Phase measurements
on L2 are ensured however as these
Receivers automatically switch to
patented tracking techniques.
GS50 - 12 L1 channels, carrier aided
code and DGPS ability.
GS50+ - 12 L1, 12 L2 channels,
code and phase, RTK capable
