For compatibility with other GNSS receivers and to minimize message size, use the standard form of RTCMV3 corrections shown in the base and rover examples in Transmitting and receiving corrections. This requires using the INTERFACEMODE command to dedicate one direction of a serial port to one message type only. When the INTERFACEMODE command is used to change the mode from the NOVATEL default, the NovAtel format messages can no longer be used.

To mix NovAtel format messages and RTCM V3 messages on the same port, leave the interface mode set to NOVATEL and log out variants of the standard correction messages with a NovAtel header. ASCII or binary variants can be requested by appending an A or B to the standard message name. For example, on the base station:

interfacemode com2 novatel novatel

fix position 51.11358042 -114.04358013 1059.4105

log com2 rtcm1004b ontime 2

 

  1. Interface mode must be set to NOVATEL for the receiver to issue logs with an A or B suffix.

  2. Using the receiver in NOVATEL mode consumes more CPU bandwidth than using the native differential messages as shown in Base station configuration.

  3. To find information on how to send multiple commands and log requests from a computer, search our knowledge database available at novatel.com/support.

At the rover, leave the interface mode default settings (interfacemode com2 novatel novatel). The rover recognizes the default and uses the corrections it receives with a NovAtel header.

The PSRDIFFSOURCE command and RTKSOURCE command set the station ID values that identify the base stations from which to accept pseudorange or RTK corrections. They are useful commands when the rover station is receiving corrections from multiple base stations.
