3.3.4 Configuration Notes

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.

3.4 GLIDE

NovAtel’s GLIDE is a positioning algorithm for single-frequency GPS and GPS/GLONASS applications.
GLIDE produces a smooth position output tuned for applications where time relative accuracy (pass-to-pass)
is more important than absolute accuracy. Because of this, it is well suited for agricultural applications.

Multipath signals tend to induce time varying biases and increase the measurement noise on the L1/L2
pseudorange measurements. Carrier phase measurements are much less susceptible to the effects of
