Understand how it works.
Choose what suits your task.

The AUTO mountpoint uses the position sent by NtripClient to select the representative mountpoint of the nearest available reference station. It selects a source when you connect, then reviews your latest position every 10 minutes.

If another available station is closer, AUTO switches the correction source while keeping the connection between NtripClient and the Caster open.

At high speed, you may travel far from the selected station before the next 10-minute review. If you need the source to follow your movement promptly, relying only on scheduled AUTO switches is not recommended.

Near the midpoint between stations, a small position change can alter which station is nearest. AUTO selects using your position at each review, so the source may change at a 10-minute review. If distances are equal, it keeps the current station.

You generally do not need to change constellation settings. Normally, keep all constellations enabled. Poor satellite geometry or reception conditions can reduce positioning accuracy.

Consider reviewing the output constellations when you can identify a particular constellation’s geometry or reception as a cause of degraded accuracy. This setting selects whole constellations, such as GPS, rather than individual satellites.

You generally do not need to change MSM output. Normally, choose “Keep input” to distribute the MSM format received from the reference station.

If your receiver or software supports MSM4 but cannot handle the incoming MSM5/6/7, clone the mountpoint and provide an output converted to MSM4. Check the supported formats in your equipment’s documentation.
