Process to apply a GLONASS Auth code to an RT or xNAV
- Ensure that the computer is correctly configured to communicate with the RT. To do this the first part of the computers IP address must match that of the RT (195.0.0.xx). For assistance on this please refer to the “Network Configuration Guide” which can be requested from firstname.lastname@example.org
- Turn on the RT and connect it to the computer using Ethernet.
- Open “Enginuity” and ensure that packets are being received from the RT by checking that the packet count is increasing in the top right corner of the window as shown below.
- Open the “Calibration” window and have the “GPS Chars Received” parameter visible (near the top of the list) as shown below.
- Open the “Quick Config” window and select the “Advanced” tab as shown below.
- Type the following command into the command line followed by the auth code as show above:
!SEND GPS1 AUTH <Auth Code from OxTS>
- Press “Apply” and watch the “GPS Chars Received” counter in the “Calibration” window. It should stop counting and then restart again after about 10 seconds. At the same time the GPS LED on the front of the RT should flash orange a few times.
- Turn the RT off and then back on again.
- Test the RT with a base station to check that the “Position Update” and “Velocity Update” in the “Performance” window go to “RTK Integer” as shown below (this step is optional but highly recommended).
Applying a GNSS Auth code to the RT Base
The process to apply a GNSS auth code to a RT Base is a little more complicated, but it can be done in the field and does not need be returned to OxTS.
You will need a laptop and a null modem cable to connect to the RT Base, and you will need to download the NovAtel Connect software and follow the instructions to communicate with it as described in this article and issue the following command:
AUTH <Auth Code from OxTS>
