After configuring the receivers for measuring, each receiver needs to be setup up and the
receiver's height measured and the measuring can begin. The TriPad provides quick access for
logging data, changing receiver modes, and viewing general data logging and satellite information
during a measuring.

4.1. Receiver Setup

A typical GPS measuring system consists of a Base station set up over a known point and a Rover
receiver set up to be a mobile data collector. After setting up the Base and Rover receivers, the
antenna height must be measured.
Before collecting data, make sure the Base and Rover receivers contain a current almanac and
current ephemeris data (see "Collecting Almanacs and Ephemerides" on page 39).

4.1.1. Set up Receiver

The Base station must be set up, logging data, and transmitting data before setting up the Rover
receiver. Receiver setup for either post-process or RTK measurings is the same.
To set up the Base receiver:
1. Place the ALPHA receiver's external GNSS antenna on the appropriate position.
2. Center the receiver's external antenna over the point at which data will be collected. For
most applications, this should be at a location with a clear view of the sky.
To set up the Rover receiver:
1. Attach the ALPHA external antenna to the bipod/range pole. Make sure the antenna locks
into place.
