Ray 70 Interface with E-120 Classic

Tim,

I suspect that there would be little or no difference in the GPS accuracy of a Raystar 130 GPS Sensor and the internal GPS sensor of a Ray70. Depending upon the installation location of the Ray70, it is quite possible that the Raystar 130 GPS Sensor would provide the system with more accurate position given that the Raystar 130 GPS Sensor was designed to be installed in a location affording it an unobstructed view of the skies overhead. With respect to accuracy, most GPS sensing devices will achieve 3m accuracy when installed in a location affording them to receive good GPS satellite signal strength. The Ray70's internal GPS sensor should be configured OFF when interfaced to a SeaTalkng backbone featuring a GPS data source.
