Owing to Big Dipper wave filter only can filter out Big Dipper radiofrequency signal, so when object location mode is Big Dipper locator means, radio frequency path can only filter out Big Dipper radiofrequency signal. Owing to radio frequency path in the application can only filter out Big Dipper radiofrequency signal, can only utilize Big Dipper radiofrequency signal so follow-up, adopt Big Dipper location technology to position. Therefore, present application addresses the problem only using Big Dipper radiofrequency signal to utilize Big Dipper location technology to position.

Under the global position system shown in Fig. 3, radio frequency antenna 100 can send radiofrequency signal to radio frequency path 500, and radio frequency path can utilize the Big Dipper wave filter 501 in prime filtering circuit 510 to carry out filtering, thus only filters out Big Dipper radiofrequency signal.In order to facilitate follow-up Base-Band Processing device 400 to carry out data processing, it is possible to adopt low-noise amplifier 502 that Big Dipper radiofrequency signal is carried out amplification process. Then, the Big Dipper radiofrequency signal after amplification is sent to Base-Band Processing device 400 through RF transceiver 300. Big Dipper radiofrequency signal is utilized to position by Base-Band Processing device 400.
As shown in Figure 4, the application provides the implementation two of radio frequency path, and on radio frequency path 500 basis shown in Fig. 3, radio frequency path 500 can also comprise rear class wave filter 503.
The input terminus of described rear class wave filter 503 is connected with the output terminal of described low-noise amplifier 502. The output terminal of described rear class wave filter 503 is connected with the input terminus of described RF transceiver 300. Described rear class wave filter 503, carries out secondary filtering for the described target radio frequency signal after the amplification that exported by described low-noise amplifier.
The object increasing rear class wave filter 503 is filter the noise in Big Dipper radiofrequency signal further, so as Base-Band Processing device 400 can analyzing and processing Big Dipper radiofrequency signal accurately, and utilize Big Dipper radiofrequency signal to position.
Above-mentioned two kinds of implementations only comprise Big Dipper wave filter 501 in radio frequency path 500, owing to current GPS location technology is still main flow location technology means. In order to make the range of application of satellite positioning tech that the application provides more extensive, the application provides the implementation three of radio frequency path 500.
See Fig. 5 and Fig. 6, for the application provides implementation three and the implementation four of radio frequency path. The basis of Fig. 3 or Fig. 4 can also comprise in the prime filtering circuit 510 of radio frequency path 500: controlled switch 511 and GPS ripple filter 512.
