Introduction
Recently I revisited OpenPlotter after a two year interval to see what had changed in the latest version 3 (Ref.1/3). I tested the Starter and Headless images and setup AIS & GPS on RPi4/OpenCPN. In 2021 I had looked at various aspects of version 2 (Ref.4/5). In this post I will look at OpenPlotter3 Starter 32bit image on RPi3B and AIS/GPS on OpenCPN as shown in Figure 1.
OpenPlotter3 on RPi3B
Figure 2 shows the applications installed after turning up OP3/32bit Starter image. I installed PyPilot/I2C Sensors/GPIO & SDR VHF. Figure 3 shows the SDR VHF menu, I then installed Gqrx. AIS and Gqrx both use the RTL-SDR, so you have to activate one or the other. Figure 4 shows activation of the AIS process. Figure 5 shows the Serial menu, where the GPS connection is given an alias and setup for NEMA0183/4800bps. If the AIS/GPS are setup correctly, then you should see entries on the Signal K Server menu as in Figure 6. Figure 7 shows the OpenCPN Connections menu for the Signal K server. Figure 8 shows the GPS location (red boat) and AIS contacts in the Toronto Harbour area.
