[0002] Global Navigation Satellite System (GNSS) is widely used in vehicle positioning, mobile phone positioning, and weapon systems, deeply integrated into our systems and facilities; some call it an "invisible tool." From transportation navigation, the Internet of Things in communications, power, finance, and defense, we are increasingly reliant on GNSS. Because GNSS signals are relatively weak when they reach the ground, interference and spoofing can cause serious damage and pose a threat to public safety. Therefore, the anti-spoofing and anti-interference performance of GNSS receivers is particularly important. Currently, testing the anti-spoofing and anti-interference performance of GNSS receivers faces challenges such as complex testing environments, cumbersome testing methods, low testing efficiency, and incomplete coverage of testing scenarios. Summary of the Invention

It proposes an automated testing platform and method for the anti-spoofing and anti-interference performance of GNSS satellite receiving modules, including automated testing methods for forwarding spoofing, generating spoofing, traction spoofing, and interference. Finally, it automatically generates test reports according to specifications and provides them to users.

[0005] Furthermore, the GNSS deception and interference integrated testing system includes an automated control system for the anti-deception and anti-interference performance of the GNSS satellite receiving module and an automated analysis system for the anti-deception and anti-interference performance of the GNSS satellite receiving module; The automated control system for anti-deception and anti-interference performance is used to set parameters for the deception / interference scenario based on the power of the real GNSS satellite radio frequency signal analyzed by the spectrum analyzer. This includes setting the deception / interference signal strength level (divided into four levels: low, medium, high, and suppression) and time parameters; and controlling the output of the real GNSS satellite radio frequency signal, the deception signal, and the interference signal. The automated anti-spoofing and anti-interference performance analysis system is used to receive test data from GNSS satellite receiving modules, determine the performance qualification according to the specifications, and automatically generate an anti-spoofing and anti-interference performance test report containing scenario test data, which is then provided to the user.
[0006] Furthermore, the parameter settings include: Users select the deception / interference scenario and set the power of the deception or interference signal based on the power of the real GNSS satellite radio frequency signal analyzed by the spectrum analyzer. The power setting is then checked by the value returned by the spectrum analyzer. Users can also set the deception signal delay, deception location and time, traction deception step size and pull-off duration.
[0007] Furthermore, the input ports of the automated control system for anti-spoofing and anti-interference performance are respectively connected to the output ports of the GNSS satellite antenna, the GNSS timing security performance indoor and outdoor test system, the ESG vector signal source, and the spectrum analyzer. The input port of the GNSS satellite signal distribution device is connected to the automated control system for anti-spoofing and anti-interference performance. The radio frequency signal input terminal of the GNSS satellite receiving module is connected to the output port of the GNSS satellite signal distribution device. The input port of the automated analysis system for anti-spoofing and anti-interference performance is connected to the output port of the GNSS satellite receiving module.
[0008] Furthermore, the GNSS satellite receiving module can also be wirelessly connected to the GNSS satellite signal distribution device.
[0009] Furthermore, the deception scenarios include different deception signal powers, times, and locations, as well as generative deception scenarios, relay deception scenarios, and traction deception scenarios in the power-on / running state of the GNSS satellite receiving module; the interference scenarios include in-band interference scenarios and out-of-band interference scenarios.
[0010] Furthermore, the test data includes spoofing interference alarm indication, 1PPS timing status indication, positioning validity flag, positioning result, number of satellites received, and GNSS satellite receiver module version number.
[0011] Another aspect of the present invention proposes an automated testing method for the anti-spoofing and anti-interference performance of a GNSS satellite receiving module. The automated testing method is executed based on any of the aforementioned automated testing platforms and includes: Step 1: Select test scenarios in the GNSS deception and interference integrated test system. The test scenarios include deception scenarios (generative deception, forwarding deception, or traction deception) and interference scenarios (in-band interference or out-of-band interference). Step 2: Based on the actual GNSS satellite radio frequency signal power analyzed by the spectrum analyzer, set the parameters for the corresponding test scenario (including the power settings of the spoofing or interference signal, the spoofing scenario time, the spoofing signal delay, the spoofing position and spoofing time, the traction spoofing step size and the pull-off duration, etc.). Step 3: The GNSS satellite signal distribution device receives real GNSS satellite radio frequency signals, spoofing signals, and interference signals, and performs lossless merging to generate a test signal for spoofing or interference; Step 4: The GNSS satellite receiving module receives the test signal, generates test data, and sends it to the GNSS deception and interference integrated test system. The GNSS deception and interference integrated test system performs automated analysis of the anti-deception and anti-interference performance based on the test data. Step 5: Based on the automated analysis results and in accordance with the relevant standard specifications, determine whether the anti-spoofing and anti-interference performance of the GNSS satellite receiving module is up to standard; Step 6: Summarize the test results of the anti-spoofing and anti-interference performance of the GNSS satellite receiver module and automatically generate a test report.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention constructs a complete and controllable testing environment. By integrating real GNSS satellite radio frequency signals, spoofing signals, and interference signals, the automated testing platform of this invention can accurately simulate the full spectrum of radio frequency threats, from simple in-band and out-of-band interference to complex intelligent spoofing. This solves the problem that traditional testing methods have limited scenarios and are difficult to reproduce real and complex threats.
[0016] This invention achieves precise measurement and closed-loop control of test parameters. Thanks to the real-time monitoring and feedback of the actual output signal by instruments such as spectrum analyzers, this invention can accurately calibrate and dynamically adjust key parameters such as the power of spoofing / interference signals, providing a reliable benchmark for performance evaluation.
[0017] The automatically generated test report not only includes the performance indicators of the GNSS satellite receiver module under test, but more importantly, it integrates objective measured data about the test scenario itself provided by instruments such as spectrum analyzers. This makes the report a complete piece of technical evidence, clearly showing the specific performance of the GNSS satellite receiver module under exact interference / spoofing conditions.
[0018] This invention fundamentally solves the long-standing pain points in GNSS anti-interference and anti-spoofing performance testing—namely, the difficulty in scenario simulation, low testing efficiency, and strong subjectivity of results—by constructing a precise, controllable, intelligent, closed-loop, and data-reliable integrated testing platform.
