Racal Tracs Ltd. Surrey, England
RACAL/LANDSTAR RTS
In addition to the standard features
previously listed, additional
accesories can be used in conjunc-
tion with the GS50 to enhance data
collection methods. The Racal-
Landstar satellite differental module
and antenna can be used for Real
Time corrections where beacon or
reference data is not available. The
Racal module and antenna attach to
the GS50 in the same configuration
as the RTB module and antenna (see
chapter Equipment Setup - Real Time
Rover, GIS Rover). Because of the
nature of the satellite differential,
signal coverage is global (except in
the polar regions.)
Because the RACAL signal
correction is porprietary in
nature, it is necessary to
obtain a subscription to the
service.
