Power consumption and noise are two frequently encountered challenges. For GPS receivers, the reduction of power consumption and the suppression of noise and interference have become the key points in system design.
Noise is mainly generated in the process of switching from high frequency to low frequency, so the noise suppression mechanism must be implemented in this link. For example, the harmonics of the SAMP CLK signal can be minimized by configuring appropriate resistors between the RF front- end and the correlator, so as to prevent them from being mixed in the intermediate frequency (IF) chain, so as to achieve the purpose of suppressing noise. In addition, the placement and routing of individual cells on the circuit also requires proper planning, as these factors can also affect interference conditions.
The main source of power consumption is the operation of the correlator, so reducing power consumption requires the ability to control each correlator channel separately; that is, when all channels do not need to be activated, the system can automatically adjust to activate only the required correlator channels. In addition, using a backup battery can reduce the power supply voltage, which also helps to save power consumption.
Technical requirements for GPS antenna
The performance of the GPS system is closely related to the antenna. The background noise of satellite signals is generally -136dBW. In order to avoid interference, international telecommunication regulations stipulate that the signals transmitted by satellites should not be greater than -154dBW. Such weak GPS signals require the ant
