positioning accuracy
Firstly, it is about positioning accuracy. Generally, GPS positioning with a deviation of 5-10 meters is a normal phenomenon. If the positioning deviation of a product can reach tens or even hundreds of meters, such products can be ignored.
Receiving capacity
GPS is actually a receiver of satellite signals. When the GPS receiver receives signals from three or more satellites, it can calculate the geodetic coordinates of the receiver's location. If it receives four satellites, it can also calculate the altitude.
Satellite trajectory
There are a total of 24 GPS satellites orbiting the Earth in six orbits, consisting of a group of 4 satellites, with 12 satellites in each hemisphere. Most GPS receivers can track 8-12 satellites. At least 3 satellites are required when calculating coordinates.
Parallel channel
Generally, GPS devices have 2-5 parallel channels to receive satellite signals, and a maximum of 12 satellites may be visible (averaging 8). Most GPS receivers are 12 parallel channel type, which can quickly cold start and initialize satellite information, and receive better results in forest areas.
Positioning time
Positioning time refers to the time required to determine the current position when restarting the GPS receiver. The closer to the last positioning position, the shorter the start time, and the cold start time is generally longer than the hot start time.
brand
Brand is the guarantee of product quality. The reason why a brand can grow is undoubtedly due to the quality of the product. Therefore, when purchasing a car GPS anti-theft device, it is best to identify a brand with high brand awareness.
