5 Setting up the Receiver

GPS RTK Base GPS Receiver User Guide

4. If necessary, connect the GPS receiver to an external 12 V power

supply using the crocodile clip cable.

5. Mount the external radio antenna to the bracket and connect the

antenna to the receiver using the cable provided.

Fixed height tripod setup

A fixed height tripod setup is similar to a tripod setup, but is simplified

by the central leg of the tripod, that is placed directly on the control

point. If the central leg is leveled accurately, the fixed height tripod is

quick and easy to set up, and provides an accurate way to measure the

true antenna height.

1. Set up the tripod over the control point.

2. Attach the GPS antenna to the head of the tripod.

3. If using an external high-gain radio antenna, mount the radio

antenna to the radio antenna bracket that is attached to the head

of the tripod (beneath the GPS antenna).

4. Hook the receiver to the center leg of the tripod, using the tripod

clip. Alternatively, the GPS receiver can remain in the carrying

case.

External radio-modems

The most common data link for Real-Time Kinematic (RTK) operation

is a radio. The AgGPS RTK Base 450/900 receiver is available with the

following internal radios:

• 410–430 MHz (Tx/Rx, Rx only, or Tx only)

• 430–450 MHz (Tx/Rx, Rx only, or Tx only)

• 450–470 MHz (Tx/Rx, Rx only, or Tx only)

• 900 MHz (Tx/Rx, Rx only, or Tx only)
