Part 5 Operation notes
WBT-200 will do self-check once it is powered. Bluetooth and GPS
start to work when both Bluetooth LED (glows blue) and GPS LED
(glows green ) turns on. GPS automatically starts acquisition and
auto-logs. If sky is clear overhead, it requires only 40 sec for
acquisition. (If the data in its memory is still valid, it needs only
8~35 sec). After acquisition, WBT-200 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 WBT-200 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 do cold
start.
If it is not in use for over 3 months (the almanac too old).
If the recorded data is over 500 km.
After positioning, WBT-200 transfers navigation data thru export
interface as below:
Latitude
Longitude
Altitude
Speed
Date
Time(UTC time)
Estimated error
Satellite status
Receiving status
