To attain full battery capacity
for new GEB121 batteries, it
is essential to repeat between three
and five complete charge/discharge
cycles.
System description
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 connec-
tion 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.
