Transmitting And Receiving Corrections - Novatel SMART7 Installation And Operation Manual

SMART7 Operation
An example of a response to an input FIX POSITION command:
[COM2] FIX POSITION 51.11635 -114.0383 1048.2 [Carriage Return]
<OK
In this example, [COM2] is the port prompt.
This example illustrates command input to the base receiver's COM2 port that sets the position
of the base station receiver for differential operation.
If the command was accepted, the receiver responds with:
<OK
If a command is entered incorrectly, the receiver responds with:
<ERROR:Invalid Message ID
Ensure the computer does not sleep or hibernate during a logging session or data will be
lost.

3.3 Transmitting and Receiving Corrections

Corrections can be transmitted from a base station to a rover station to improve position accur-
acy. The base station is the GNSS receiver that acts as the stationary reference. The stationary
reference has a known position and transmits correction messages to the rover station. The
rover station is the GNSS receiver that does not know its exact position and requires correction
messages from a base station to calculate differential GNSS positions. An example of a dif-
ferential setup is shown in Figure 9: Basic Differential Setup on the next page.
