GPS delayed refresh

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Tim,

It is recommended that GPS sensors be installed in a location affording them an unobstructed view of the skies overhead. I have seen instances where a person closely seated or standing next to a sensor can shield it from receiving GPS satellite signal, causing issues such as you have suggested. Accordingly, installation of the GPS sensor atop the arch is preferred over a rail mount. One other cause of such problems may be a GPS sensor whose performance is degrading.

Should high HDOP be reported by the MFD's GPS status dialog and the GPS sensor be a Raystar 125 GPS Sensor, then it may be possible to restore the performance of the GPS sensor by replacing its internal CR2032 battery.
