I have been working on a project lately. To implement ReachRS to exisiting navigation system onboard.
My boat is configurated with:
Simrad GO9 XSE
Simrad 3G radar
Simrad NMEA2000 backbone with NMEA0183 adapter and AT10 converter for serial connection to ReachRS
Simrad Precision-9 Compass
Simrad totalscan structur
GO9 has buildt in 10Hz Gps, but from reading done against ReachRS, its has some large deviation from origin.
Spooky when one trust it to place the boat on the map and not make you run your boat onto nearest submergd rock
Will post a youtube clip later showing live track from 2reach units and one simrad track log.
