About GPS

The Global Positioning System (GPS) is the most

noteworthy recent advance in navigation and positioning

technology. It consists of a constellation of 24-Earth Orbiting

satellites, 24 hours provides signals at everywhere on the earth.

To position your location, at least four satellites are required to

determine the latitude and longitude.

SmartDrive SD1000 selected SiRFstar III GPS technology as the

GPS receiver. This provides rapid and deep GPS signal search

capabilities to pin point your location on the Earth. Cooperate

with the map database and the direction-sensing electronics,

your location can be displayed on the map. With SmartDrive

SD1000, you can reach your destination safely without a fear.

This device presents positional accuracy of about 2.5 meters. If

roads are close together, your current position may be placed on

the inaccurate road. Please keep driving if this happened. Your

position will be put right when the GPS get a better reception.

Time to first fix GPS may take longer time (<35 seconds) if you

remains immovability. GPS signal does not penetrate

ferroconcrete, metal and certain substances. Hence, GPS signal

may lose if you drive through tunnels, underground, bridges, tall

buildings, dense stands of trees, or adverse weather conditions.

SmartDrive SD1000 will reconnect when free of obstructions.
