Set Up the Equipment
Successful GPS surveys require
undisturbed satellite signal reception.
This means that GPS Receivers
should be set up in locations which are
free of obstructions. No obstacles like
trees, buildings, mountains, etc. should
block the line between the GPS
antenna and GPS satellites. This holds
true in particular for the Receiver which
serves as the reference.
For static and rapid static surveys,
the antenna must be kept perfectly
steady throughout the whole occupa-
tion of a point. This means that the
AT501 or AT502 antenna will usually
be put on a tripod.
Center and level the tripod precisely
above the survey marker. Place and
lock the carrier in the tribrach. Mount
the antenna onto the carrier.
Connect the antenna to the sensor
using the antenna cable.
Plug two camcorder batteries into the
backside of the sensor. Alternatively
or in addition you might want to
power the sensor externaly. In this
case connect a GEB71 battery to the
PWR- port of the sensor.
Attach the TR500 terminal to the
sensor, either directly or via a con-
nection cable by plugging it into the
TERMINAL-port on the sensor.
Insert a PC-card into the sensor.
Lock the lid carefully after
insertion of the card in order
to prevent water and dust from
getting inside the sensor.
Use the hook on the backside of the
sensor to hang it on one of the tripod
legs. Alternatively you may want to
leave the sensor inside the shipping
case.
Your System 500 sensor is now fully
ready for operation.
