Services

We run the following services, mostly to contribute to various communities or data gathering services to allow others to benefit.

AIS

I currently use an AIS unit on Grace to grab AIS data off the VHF airwaves. On board Grace, I have a Raspberry Pi 2 that runs aisdispatcher and sends only summarized data over a VPN connection to my home. I documented how I do this with a bandwidth limited cellular link.

I do this because of the data limit I have on Grace’s Internet connection, currently provided by an LTE cellular connection.  At home, I have a Raspberry Pi 2 that receives the info from the on-board system, and then sends it out to the services below.

  • MarineTraffic – my favorite site for submitting AIS due to it’s great tools and data analysis of my signal/data.
  • aishub
  • Shipfinder
  • BoatBeacon – great site and associated Boat Watch app.  Also the makers of SeaNav, a fantastic navigation app for the Mac.

SignalK

Grace has a Rasperry Pi B system connected to an ActiSense NMEA 2000 to USB gateway. It runs a number of services, but it’s primary purpose is to run the SignalK server and test instances of various UI’s. I hope to share some of this eventually, but for now it is private.

Weather

I run several weather stations, covered in more detail on my Weather page. They include:
