一般情况下，待测终端400的AGPS信号由待测终端400的移动网络模块获得，采用的是LTE Band 39频段(为国内常用频段)，完整范围是1880MHz-1920MHz，测试时，选用常用的LTE B13和LTE B14频段(LTE B13和LTE B14为国外常用频段)，分别是10MHz和 20MHz，在测试时，当GPS模拟信号和AGPS模拟信号共存时，有GPS/LTE Band 39(GPS 模拟信号和处于LTE Band 39频段内的AGPS模拟信号共存的模式)、GPS/LTE B13(GPS模拟信号和处于LTEB13频段内的AGPS模拟信号共存的模式)和GPS/LTE B14(GPS模拟信号和处于LTE B14频段内的AGPS模拟信号共存的模式)三种组合。In general, the AGPS signal of the terminal 400 to be tested is obtained by the mobile network module of the terminal 400 to be tested, using the LTE Band 39 frequency band (commonly used in China), and the complete range is 1880MHz-1920MHz. During the test, the commonly used LTE B13 and LTE B14 frequency bands (LTE B13 and LTE B14 are commonly used frequency bands abroad), are 10MHz and 20MHz respectively. During the test, when GPS analog signals and AGPS analog signals coexist, there is GPS/LTE Band 39 (GPS analog signals and in LTE Band 39 AGPS analog signal coexistence mode), GPS/LTE B13 (GPS analog signal and AGPS analog signal coexistence mode in LTEB13 frequency band) and GPS/LTE B14 (GPS analog signal and LTE B14 frequency band AGPS analog signal coexistence mode) three combinations.

可选的，当对通信频段有特殊要求时，也可以使用其他带宽进行测试。Optionally, when there are special requirements for the communication frequency band, other bandwidths can also be used for testing.

可以理解的是，上述步骤S100和步骤S200的先后顺序也可以反过来，即先测试待测终端400在GPS模拟信号和AGPS模拟信号共存时的第二定位灵敏度S2，再测试只有GPS模拟信号时的第一定位灵敏度S1。It can be understood that the order of the above steps S100 and S200 can also be reversed, that is, first test the second positioning sensitivity S2 of the terminal 400 under test when the GPS analog signal and the AGPS analog signal coexist, and then test when only the GPS analog signal The first positioning sensitivity S1.

S300.若所述第二定位灵敏度低于所述第一定位灵敏度，则所述待测终端的定位性能不符合要求；若所述第二定位灵敏度高于或等于所述第一定位灵敏度，则所述待测终端的定位性能符合要求。S300. If the second positioning sensitivity is lower than the first positioning sensitivity, the positioning performance of the terminal under test does not meet the requirements; if the second positioning sensitivity is higher than or equal to the first positioning sensitivity, then The positioning performance of the terminal under test meets the requirements.

具体的，通过比较待测终端400的第一定位灵敏度S1和第二定位灵敏度S2，当S2低于 S1时，即待测终端400在GPS模拟信号和AGPS模拟信号共存时的定位性能比只有GPS模拟信号存在时的定位性能更差，这意味着AGPS模拟信号定位对GPS模拟信号定位产生负面影响，降低了待测终端400的定位性能，因此，待测终端400的定位性能不符合要求。当S2 高于或等于S1时，即待测终端400在GPS模拟信号和AGPS模拟信号共存时的定位性能比只有GPS模拟信号存在时的定位性能更优或持平，则说明AGPS模拟信号定位提高了待测终端400的定位性能或对原有定位性能没有负面影响，因此，待测终端400的定位性能符合要求。Specifically, by comparing the first positioning sensitivity S1 and the second positioning sensitivity S2 of the terminal undertest 400, when S2 is lower than S1, that is, the positioning performance of the terminal undertest 400 when the GPS analog signal and the AGPS analog signal coexist is better than that of only GPS The positioning performance is worse when the analog signal exists, which means that the AGPS analog signal positioning has a negative impact on the GPS analog signal positioning, which reduces the positioning performance of the terminal 400 under test. Therefore, the positioning performance of the terminal 400 under test does not meet the requirements. When S2 is higher than or equal to S1, that is, the positioning performance of the terminal 400 under test when the GPS analog signal and the AGPS analog signal coexist is better or equal to that when only the GPS analog signal exists, it means that the AGPS analog signal positioning has improved. The positioning performance of the terminal undertest 400 may have no negative impact on the original positioning performance, therefore, the positioning performance of the terminal undertest 400 meets the requirements.

在本实施方式中，待测终端400的第一定位灵敏度S1利用待测终端400定位成功时的 GPS模拟信号最小强度值来表示，第二定位灵敏度S2则利用待测终端400定位成功时的GPS 模拟信号和AGPS模拟信号二者叠加时的最小强度值来表示，因此，待测终端400定位成功时的信号强度值越小，待测终端400的定位灵敏度越高。In this embodiment, the first positioning sensitivity S1 of the terminal undertest 400 is represented by the minimum strength value of the GPS analog signal when the terminal undertest 400 is successfully positioned, and the second positioning sensitivity S2 is represented by the GPS signal when the terminal undertest 400 is successfully positioned. Therefore, the smaller the signal strength value when the terminal undertest 400 is positioned successfully, the higher the positioning sensitivity of the terminal undertest 400 is.

If the interference of the AGPS analog signal to the GPS analog signal is conduction interference, then optimize the SAW (SurfaceAcoustic Wave Filter, integrated surface acoustic wave filter) in the GPS module of the terminal 400 to be tested. Filter) and LNA (Low Noise Amplifier, Low Noise Amplifier), if the interference of the AGPS analog signal to the GPS analog signal is coupling interference, then optimize the isolation between the AGPS antenna and the GPS antenna of the terminal 400 to be tested.

其中，分析AGPS模拟信号对GPS模拟信号的干扰是否为传导干扰，具体为：Among them, analyze whether the interference of the AGPS analog signal to the GPS analog signal is conducted interference, specifically:

确认待测终端400的GPS模块的C/N值(Carry/Noise，载噪比)是否大于-30db，若是，则GPS模块的C/N值达标，若不是，则优化待测终端400的GPS模块中SAW和LNA的匹配度。Confirm whether the C/N value (Carry/Noise, carrier-to-noise ratio) of the GPS module ofterminal 400 to be tested is greater than-30db, if so, the C/N value of GPS module is up to standard, if not, then optimize the GPS ofterminal 400 to be tested Matching degree of SAW and LNA in the module.

在本实施例中，AGPS天线为手机频段B13天线，当然，AGPS天线的具体类型也可以根据实际需求进行调整。In this embodiment, the AGPS antenna is a mobile phone frequency band B13 antenna. Of course, the specific type of the AGPS antenna can also be adjusted according to actual needs.

进一步的，判断B13/B14频段的传导二次谐波是否低于-75dBm，若是，则B13/B14频段的传导达标，若不是，优化B13/B14频段的传导匹配。Further, judge whether the conduction second harmonic of the B13/B14 frequency band is lower than -75dBm, if yes, the conduction of the B13/B14 frequency band meets the standard, if not, optimize the conduction matching of the B13/B14 frequency band.

具体的，当B13/B14频段的传导二次谐波低于-75dBm，设计Nortch(陷波滤波器)匹配，直至B13/B14频段的传导二次谐波低于-75dBm。Specifically, when the conducted second harmonic in the B13/B14 frequency band is lower than -75dBm, design a Nortch (notch filter) to match until the conducted second harmonic in the B13/B14 frequency band is lower than -75dBm.

其中，分析AGPS模拟信号对GPS模拟信号的干扰是否为耦合干扰，具体为：Among them, analyze whether the interference of the AGPS analog signal to the GPS analog signal is coupling interference, specifically:

确认待测终端400的AGPS天线和GPS天线的隔离度是否大于25dBm，若是，则AGPS天线和GPS天线的隔离度达标，若不是，则优化AGPS天线和GPS天线的隔离度。Confirm whether the isolation between the AGPS antenna and the GPS antenna of the terminal 400 to be tested is greater than 25dBm, if yes, the isolation between the AGPS antenna and the GPS antenna meets the standard, if not, then optimize the isolation between the AGPS antenna and the GPS antenna.

具体的，在应用本发明实施方式提供的终端定位性能的优化方法前后，待测终端400的定位灵敏度如下表所示：Specifically, before and after applying the terminal positioning performance optimization method provided by the embodiment of the present invention, the positioning sensitivity of the terminal 400 to be tested is shown in the following table:

表1待测终端400应用终端定位性能的优化方法前后的定位灵敏度对比Table 1 Comparison of positioning sensitivity before and after applying the terminal positioning performance optimization method for the terminal 400 to be tested

由表1可知，在待测终端400进行优化前，当GPS模拟信号和AGPS模拟信号共存时，待测终端400定位成功所需的最小信号强度值是-138dBm，大于只有GPS模拟信号时待测终端400定位成功所需的最小信号强度值-147dBm，即待测终端400的定位灵敏度降低明显，不符合要求。当用本实施方式提供的终端定位性能的优化方法对待测终端400进行优化后，可以看到，当GPS模拟信号和AGPS模拟信号共存时，待测终端400定位成功所需的最小信号强度值是-146dBm，与只有GPS模拟信号时待测终端400定位成功所需的最小信号强度值 -147dBm相比，仅增大了1dBm，可以达到要求。当然，若需要进一步提高待测终端400的定位性能，可以使用上述终端定位性能的优化方法继续优化待测终端400。It can be seen from Table 1 that before the optimization of the terminal 400 to be tested, when the GPS analog signal and the AGPS analog signal coexist, the minimum signal strength value required for the successful positioning of the terminal 400 to be tested is -138dBm, which is greater than when only the GPS analog signal is used. The minimum signal strength value required for successful positioning of the terminal 400 is -147dBm, that is, the positioning sensitivity of the terminal 400 under test decreases significantly, which does not meet the requirements. After the terminal 400 under test is optimized using the terminal positioning performance optimization method provided in this embodiment, it can be seen that when the GPS analog signal and the AGPS analog signal coexist, the minimum signal strength value required for successful positioning of the terminal 400 under test is -146dBm, compared with -147dBm, the minimum signal strength value required for the successful positioning of the terminal 400 under test when only the GPS analog signal is present, is only increased by 1dBm, which can meet the requirement. Of course, if it is necessary to further improve the positioning performance of the terminal undertest 400, the above method for optimizing the terminal positioning performance may be used to continue optimizing the terminal undertest 400.

可以理解的是，在上述第一实施方式和第二实施方式中，待测终端400可以是手机、智能手表、平板电脑、笔记本电脑等具有GPS定位和AGPS定位的终端，本发明实施方式对此不作具体限定。It can be understood that, in the above-mentioned first embodiment and second embodiment, the terminal 400 to be tested may be a mobile phone, a smart watch, a tablet computer, a notebook computer, etc., which have GPS positioning and AGPS positioning.
