Yes, lightning, climate (overcast, rainy and cloudy) etc., all may affect the signals and use of
GPS.
2. What factors may affect the signals of GPS?
1) SA satellite message is from DOD in USA. The precision of GPS signal is directly
controlled by DOD in USA, in order to ensure security, the signal precision for civilian use is
lower than that for army, so in some sensitive places, military base for example, the signals
can be interfered and the precision of positioning may be reduced.
2) Weather factors (macula, bad weather may reduce the intensity of signals and result in
instable orientation.)
3) Electric, electromagnetism, wireless wave and strong magnetic field all has different certain
interference.
4) Under veils, such as buildings, cars, heat insulation papers, metal veils and trees, they all
may reduce the signals of GPS, therefore, place the device close to the windshield.
3. Why does not GPS receive signals in buildings?
The signals can be obstructed easily by buildings and metals, and they can't penetrate
through the wall of buildings, so the GPS can't be used in buildings.
4. Does the affect the signals of GPS?
It will have certain effect on GPS when the material of sun membrane contains metal.
It supports quick global positioning, stable signals, free of service, detailed map for each city,
voice navigation for the whole journey, intelligent lay out the route, operation system of
Microsoft windows CE.net, 5.0 inch TFT touch screen with 65k colors internal GPS and high
capacity rechargeable LI-polymer battery
vehicle tint
5. How long does the GPS take to position after power on?
About 1 minute the GPS begins to positioning if it is located in wide and non-interference
places, less than or equal to 5 minutes is in accordance with the standard of GB/T 19392-
2003-5.3.
6. What is the maximum navigation time? How long does it take to charge up?
Maximum navigation time: 3-4hrs with volume and brightness at 50%.
Time for charging: 3-3.5hrs under standby mode, the time will be different in different
surroundings, the unit can also be charged when power on, but the time shall be longer, it is
normal that the unit heat while charging.
7. What advantages does our GPS solution have?
.
8. Normally, how many satellites can GPS receiver capture?
Normally, most GPS receivers can capture 8-12 satellites.
9. Will the music be distorted if the volume is too high? Sometimes WMA files can not
be played, why?
Please make sure whether the music is obtained legally? If not it must be of big noise. WMA
files has copyright protecting, it needs to be decoded by decoding software during operation.
10. How to avoid device crashing at the moment of car starting up?
Users must note that do not connect the GPS with the linker until the car is started up.
