SDR AIS available in OpenPlotter 2 - Sailoog - 2020-04-20 We have just published the first version of openplotter SDR VHF app with AIS reception included. More SDR tools like gqrx will be added soon. AIS reception features are: - Both AIS channels reception with just one SDR device. - Custom output UDP port. - Automatic Signal K connection. - Multiple SDR devices supported. - Editable SDR device serials. - Tools for calibration. To install SDR VHF app you will need openplotter-settings 2.3.0. Please report bugs here. RE: SDR AIS available in OpenPlotter 2 - holgerw - 2020-04-21 Great Work, Sailoog. if anybody has an old version aktive, you should disable this service first, look into this thread: http://forum.openmarine.net/showthread.php?tid=2417&pid=13429#pid13429 stay well, holger RE: SDR AIS available in OpenPlotter 2 - verkerkbr - 2020-04-21 (2020-04-20, 07:26 PM)Sailoog Wrote: We have just published the first version of openplotter SDR VHF app with AIS reception included. RE: SDR AIS available in OpenPlotter 2 - Sailoog - 2020-04-21 To get AIS data you only need to select a device and set the PPM and the UDP port values. All options in "calibration" section are just to find out the PPM of your device. Short calibration manual
PPM values have a tolerance of +/-7. PPM value can be negative. If you do not find the correct PPM you will not get AIS data. The PPM value will change with temperature so let the device work for 30 minutes before calibrating. Some devices are already calibrated (PPM near 0) even with different temperatures. RE: SDR AIS available in OpenPlotter 2 - abarrow - 2020-04-21 I have it working. I tried entering my -1.78 ppm in the correct field and got an error. Since it was so low, I just entered 0 and it's all working. Thanks for your hard work on this.

Can not wait to add more tools You have to thanks to e-sailing too, we did that together RE: SDR AIS available in OpenPlotter 2 - dione - 2020-04-21 Running my SDR, and receiving data in Opencpn through the K signal. The calibration is the same as the one I had done manually. Thank you, RE: SDR AIS available in OpenPlotter 2 - verkerkbr - 2020-04-22 At first I tried this on my AMD64 system. Install from the OpenPlotter Settings gave an error about a postinstall.... file missing. Then I installed the application from Synaptic. No error with the installation. Switched on the Ais application. It seems to be working. But looking at the "sudo systemctl status openplotter-rtl_ais.service". There the outcome is displayed as "disabled". Switched the autostrart on and rebooted the system. Now the message is "enabled" . However I have not seen any objects passing by. But perhaps there are no ships here at rhe moment. Then I did the same thing on my RPI4 with the V8 kernel. All seems to work. Message enabled. But in the end i get the message: Detected Kernel usbfs nmap () bug. falling back to buffers in userspace.

That is the expected behavior for enable/disable status You need to provide the correct ppm to see AIS blanks and to have some ship around of course I can not help with errors with beta kernel because we use only stable kernels to develop RE: SDR AIS available in OpenPlotter 2 - Przemek - 2020-04-22 (2020-04-22, 06:34 PM)Sailoog Wrote:(2020-04-22, 06:14 PM)verkerkbr Wrote: At first I tried this on my AMD64 system.

I make those steps as You give in SD VHF app but I have to make connection manually. Do I have to use SignalK server? I have error on system check that there's no connection to opencpn. https://photos.app.goo.gl/ccygZ2ePo247XobN7 Regards Przemek |
