Introduction
The RDS A100 GPS Receiver uses SBAS* to enable 50cm accuracy 95% of
the time (assuming good reception). It is pre-configured for operation with
the PSi head unit and/or the ASC 200 Automatic boom section Controller.
* SBAS Satellite-Based Augmentation System providing a differential
correction signal e.g, EGNOS (European Geostationary Navigation
Overlay Service) or WAAS (Wide Area Augmentation System)

Mountin the antenna
• The receiver comes fitted with a short mounting stalk with magnetic base.
Mounting on a plastic roof will require a metal base plate (not included) to be
attached by suitable means. Run the combined antenna/power cable into the
cab.
• Mount the antenna in the location or which you desire a position e.g. along
the centre line of the vehicle and as close as possible over the working
interface.
NOTE: As this may well be impractical to achieve, the Pro-Series can be
programmed via the PF SETUP menu with GPS ANTENNA OFFSETS to
compensate for the difference in position of the antenna from the cutter bar,
spray boom etc.
• Mount the antenna to give an unobstructed hemisphere o sky. This will
ensure that GPS satellites are not masked by parts of the vehicle, potentially
reducing system performance.
• Wherever possible, avoid drilling holes in the roo to avoid both water ingress
and possibly wiring / air conditioning equipment etc. If drilling is unavoidable,
use silicone sealant around fixing and cable entry points.
• Mount the antenna as ar as possible rom any equipment that can cause
Electromagnetic Inter erence (EMI) including DC motors (e.g. air conditioner),
alternator, solenoids, CB radio, power cables, display units, or other
electronics. Excessive EMI will degrade system performance.
TIP: To detect possibly troublesome interference, tune a W band portable radio
off-station. With the aerial laid flat you can then (hopefully) pick up the
direction and source of the interference from the increase in noise. The
antenna can then be repositioned or if necessary, the source of the
interference suppressed. If need be, contact RDS for further advice on
suppression methods.
• Secure the antenna cable close to the antenna mounting (using cable ties) so
that in the event the antenna is knocked off it's magnetic mounting, it will be
restrained and minimise the possibility of further damage.
