Setting up the Receiver 5

Setting up a mobile base station: Tripod and fixed height

tripod

If you are repeatedly moving between fields, Trimble recommends that

you use either a tripod and tribrach setup, or a fixed height tripod.

The fixed height tripod is quicker and easier to set up over a control

point. Take great care to ensure that the GPS antenna is set up

accurately over the control point, and that the GPS antenna height is

measured accurately, in the right way (vertical or slope height) to the

right location on the antenna (base of antenna or to a specified location

on the antenna). When you start the rover receiver, it is extremely

important to check in, at one or more known locations, to check for

possible position or height errors.

Checking in at a known location is good practice and can avoid costly

errors caused by a bad setup.

Typically, the tripod and fixed height tripod methods do not give

significant height clearance above the ground, and can reduce the range

of operation caused by radio limitations.

Tripod and tribrach setup

In the tripod setup, the tripod is located over the control point, and the

tribrach and tribrach adaptor is mounted on the tripod and centered

over the point.

1. Place the external antenna bracket on the tribrach adapter and

mount the GPS antenna on the tribrach adaptor sandwiching the

external antenna bracket to hold it in place.

2. Clip the GPS receiver to the tripod if desired. Alternatively, the

GPS receiver can remain in the carrying case.

3. Connect the GPS antenna to the receiver using the cable

provided.
