There are many factors determine the signal, GPS navigation chip is equipped with the most important, currently used Sir Star III high sensitivity chipset products tend to have better signal capability, such products to receive the signal even difficult to distortion, can well avoid “drift” phenomenon. In addition, search star speed, number, signal strength and stability can reflect on this product in the signal reception performance, we should pay more attention to the time of purchase and trial.
2 Configurations
A good product in hardware performance must be satisfactory, if the hardware performance is too low; GPS navigation systems will appear slow to respond, crashes, instability and even found less than satellite, and so adverse conditions.
