BackDefault and Recommended Settings for GEODE
30 May 2023
The Geode default settings are designed for reliability in most situations. Using Geode Connect to perform a Soft Reset can apply other recommended settings. Our Uinta app can also automatically apply recommended settings to the Geode. (See Uinta Auto-configures Geode for details.) Otherwise, you can manually apply recommended settings such as the following.
- Antenna Mask Angle. The default is set to 10º to get the highest-quality signal. If you're working in semi-obscured environments, such as heavy tree canopy, you can reduce the angle to 5º or even 0º to increase the number of satellites the Geode can see.
- Receiver Mode Settings
- Mixed. This includes satellites that do not have a DGPS correction in the position solution. While this is useful for obtaining a solution in environments with varied sky obstructions, this can reduce the overall accuracy of the position solution. Setting this to OFF (Unchecked) will force the receiver to only use corrected satellite signals in the position solution. Turn off mixed to get the highest possible accuracy.
- SBAS Ranging. This allows the receiver to use an SBAS satellite like a GPS satellite for tracking and setting the internal receiver clock. This is normally set to OFF, as the SBAS clock signal may not match the GPS clock signals and could induce some error. SBAS ranging can be used in environments with poor satellite coverage where SBAS is available.
- Tunnel. This allows the receiver to estimate a position for faster reacquisition when coming out of a tunnel based on the previous direction of travel. The default setting is OFF to prevent the receiver from making incorrect position assumptions.
- SureTrack. This does not apply to GNS3. Similar functionality in the GNS3 is achieved using the SureFix feature, which is always enabled. In GNS1 & GNS2 the default is enabled. SureTrack ensures RTK-based solutions use every available satellite.
- Active GNSS Constellations. This allows you to set GPS and all other GNSS constellations to active. Please see Cannot Turn on Multi-GNSS on Geode Connect, if you are having such a problem.
- Corrections Source. Default to Auto, which will selectively apply the best corrections service that it is receiving, based on a pre-defined order. When set to Auto the receiver will try to resolve positions using
- ATLAS (if available)
- SBAS (if available)
- External corrections (such as NTRIP)
