System biases can introduce errors, as described in the Modes of Operation chapter in the GPS+ Reference Guide. In most cases you need to provide a data link between the base station and rover station (two NovAtel receivers) in order to receive corrections. SBAS corrections can be accomplished with one receiver and are exceptions to the base/rover concept. Generally a link capable of data throughput at a rate of 9600 bits per second, and less than 4.0 s latency, is recommended.

Once your base and rover are set up, you can configure them as shown in the configuration examples that follow in Sections 3.3.1 - 3.3.2 starting on Page 32.
