Operation notes
G-RAYS 2 will do self-check once it is powered. Bluetooth
and GPS start to work when both Bluetooth LED (glows blue)
and GPS LED (glows red) turns on. GPS automatically starts
acquisition and auto-logs. If sky is clear overhead, it requires
only 34 sec for acquisition. (If the data in its memory is still
valid, it needs only 4~33 sec). After acquisition, G-RAYS 2
starts output data of position, speed and time in NMEA0183
format.
For the first time if it is placed at the area well exposed to the
satellite signal, this device requires approx 13 min
(theoretically 12.5 min) to receive or update Almanac. Refer to
trouble shooting guide when signal is not received well.
If G-RAYS 2 formatting the internal data is not correct, or if
satellite data has been deleted, it takes longer time to position.
But under the following conditions, it can take even longer
time to get cold start.
If it is not in use for over 3 months (the almanac is old-
dated).
If the last recorded position data is over 500 km.
After positioning, G-RAYS 2 transfers navigation data thru
export interface as below:
Latitude
Longitude
Altitude
Speed
Date
Time(UTC time)
