a) Range, b) Signal Strength (RSSI) and c) Signal to noise ratio (SNR)?

[OculoDoc]

Hi everyone,

I'm using a Pi with an AIS/NMEA hat as a receiver.
Input to OpenCPN is via serial port ttyS0. OpenCPN outputs to marinetraffic.com etc.

How do I:
- The range (distance) of signals I'm receiving over time?
- The signal strength per vessel?
- The signal to noise ratio?

Thank you,

OculoDoc

Range for all vessel you find in the AIS target list --> right click on canvas.

The other data are not available. This would be a feature of the SDR plug-in.
A standard AIS receiver does not report signal strength related data.
