15
TROUBLE SHOOTING
The GPS signal will become not good enough under the environment of tall buildings
and trees. Even though the WGM-302 can receive reected GPS signal, the data
might be less accurate.
Some car window lm comprising too many metals would affect a reception of signal.
The unstable atmospheric condition will effect a worse accuracy; however, if the
location on map is always shifted no matter how signal is, please reconrm if the
datum system on the map you used is the standard WGS-84 or not.
The WGM-302 utilizes initial data, such as last stored position, date, time and
almanac data, to achieve maximum acquisition performance. If significant
inaccuracy exists in the initial data, or the almanac data is obsolete, it may take
more time to get acquisition, e.g. your current location is 500km away from the latest
location you used it, or the device isn’t used for three months.
Avoid placing 2 GPS devices too close during positioning.
Before connecting the WGM-302 to the computer, please make sure the USB driver
has been installed and the right COM Port has been selected. (USB interface only)
If the WGM-302 is not working for navigation under correct connection and data
output, please reconrm the format of NMEA 0183 for your navigation software, and
set it via the WGM-302 Tool.
