Configure Receiver for HD2 Operation
HD2 Overview
The MR-2 can process accurate and instantaneous attitude parameters. The MR-2 combines a pair of B125
receiver boards, and two external antennas, to create a 2D system for heading and pitch. With this method,
one board acts as a moving base, and the other as a rover. The antennas are fixed, and the inter-antenna
distance is constant. The moving base sends standalone position and raw data to the rover, which processes
the data and sends them using ASCII or binary messages.
You can also configure the moving base to accept RTK measurements from a stationary base station. With this
method, the moving base is used as a base and a rover simultaneously. The moving base will process its
position, with centimeter level accuracy, using the measurements from the stationary base station. It will then
transmit the position to the rover.
HD2 operation requires scripts that will configure the receiver by sending commands to the master board of the
MR-2. Several scripts are available on the Topcon Positioning Systems website, which cover the popular work
flows of the MR-2, and can be modified for custom applications.
1. Go to

2. Connect the primary receiver board to TRU. For more information about connecting to the receiver using
TRU, see
“Connect The Receiver to TRU” on page 20.
3. Under Software, locate the scripts, click the Download icon, and save the scripts to your computer.
HD2 Heading Determination (OCTO) OAF options must be enabled, in addition to a minimum of GPS
L1/L2 signal tracking.
