GPS Receiver User’s Tip
A. GPS signals are affected by weather and environmental conditions. It is
suggested to use the GPS receiver under less shielding environments to
ensure GPS receiver has better receiving performance.
B. When GPS receiver is in moving condition, it will prolong the time to fix the
position. It is suggested to wait for the satellite signals to be locked at a
fixed point when first power-on the GPS receiver before using.
C. The following situations will affect the GPS receiving performance:
i.
ii.
Solar control filmed windows.
Metal shielded, such as umbrella, or in vehicle.
Among high buildings.
iii.
iv.
v.
Under bridges and tunnels.
Under high voltage cables and near by radio wave sources, such as
mobile phone base stations.
vi.
Bad and heavy cloudy weather.
D. If the satellite signals can not be locked or have encountered receiving
problem (within the urban area), the following steps are suggested:
i.
Plug the external active antenna into the GPS receiver and set the
antenna outdoor or on the roof of the vehicle for better receiving..
Move to another open space or reposition the GPS receiver towards the
direction with fewer blockages.
ii.
iii.
iv.
Move the GPS receiver away from sources of interference
Wait until the weather condition has improved.
E. With a backup battery, the GPS receiver can fix a position immediately at next
power-on if the built-in backup battery is fully charged.
