Surveying With An External Gps Receiver - Topcon BR-1 Operator's Manual

BR-1 Surveying with an
External GPS Receiver
When surveying with the BR-1 in an external GPS receiver
configuration, the Beacon receiver provides DGPS data correction to
the GPS receiver. When using this system configuration with a data
controller, make sure to connect the BR-1 and GPS receiver using a
port other than the one used for the controller.
1. Complete any required set up steps for the BR-1 as described in
Chapter 2.
2. In the field connect the BR-1 and GPS receiver with a serial
cable, turn on the external GPS reviver and the BR-1.
3. If using a serial connection, make sure to connect the optional
GPS receiver-to-BR-1 serial cable to both devices.

4. Begin surveying according to the external GPS receiver's manual.
The surveying may be conducted using just the GPS receiver, or a
controller (such as the FC-200 or GMS-2) also connected to the
the GPS receiver.
