[0046] Many specific details are set forth in the following description to provide a full understanding of this specification. However, this specification can be implemented in many other ways than those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this specification. Therefore, this specification is not limited to the specific implementations disclosed below.

These terms are only used to distinguish information of the same type from one another.

Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to a determination."
[0049] This specification provides a method for selecting and verifying aerospace sensors. It also relates to an aerospace sensor selection and verification device, a computing device, and a computer-readable storage medium, which are described in detail in the following embodiments.
[0050] See Figure 1 , Figure 1A flowchart of a method for selecting and verifying aerospace sensors according to an embodiment of this specification is shown, which specifically includes the following steps.
[0051] Step 101: Determine the resolution parameters and range parameters, and determine the target sensor based on the resolution parameters and range parameters.
[0052] In one possible implementation, performance calibration of the noise of the target sensor is performed to determine the performance calibration result, including: calibrating the noise of the target sensor to determine the noise calibration result; performing accuracy calibration based on the noise calibration result to determine the accuracy calibration result; and determining the performance calibration result based on the noise calibration result and the accuracy calibration result.
[0053] In practical applications, see Figure 2 Based on mission requirements, the first step should be to select the appropriate testing parameters, primarily including resolution and range. These two parameters must meet the technical requirements. While other parameters can be designed later, these two cannot be replaced by subsequent measures. Resolution, in addition to being selected based on the product's technical specifications, must also be verified. Range should be selected based on design specifications. After selecting resolution and range, basic verification of the parameters should be conducted using ground-based verification methods.
[0054] Specifically, resolution testing: First, in environments with background vibration and noise levels 10 times or less below the resolution, the sensor's frequency range should be considered when selecting the environment. The sensor should be tested for its lowest resolution within its operating frequency band. The data acquisition equipment should also have corresponding testing capabilities. To achieve a good signal-to-noise ratio, the background noise of the channel should be less than 10 times the test level. Measurement range: The measurement range should be selected based on the characteristics of the task, generally exceeding twice the estimated maximum measurement range. This parameter depends on the sensor's design principles. Verification can be performed using a standard signal source and by calibrating the maximum measurement range.
[0055] Step 102: Perform noise performance calibration on the target sensor and determine the performance calibration results.
[0056] In practical applications, sensor calibration involves standard-level calibration of two accuracy metrics. This can be achieved by testing the sensor's resolution in a cave with background noise levels reaching 1*10⁻⁷ g and data acquisition system noise reaching 1*10⁻⁸. After achieving these parameters, standard-level calibration is then performed on the sensor's dynamic range and linearity. Following this standard-level calibration, a smaller-scale calibration is also necessary.
[0057] Specifically, measurement accuracy testing: Accuracy is measured from two aspects: amplitude linearity and dynamic range. Generally, standard signal source calibration is used for verification. Dynamic range calibration should cover the required frequency band, and amplitude linearity should cover all test ranges. Measurement accuracy testing should be performed again after all environmental tests are completed to ensure the sensor's operational status. Furthermore, based on the sensor's operating characteristics, separate accuracy tests should be conducted for sensitive environmental factors, and accuracy compensation measures should be developed. Amplitude linearity should generally be better than 5% within the test frequency band. Amplitude range should generally be better than 1% within the measurement range.
[0058] Step 103: Determine the physical parameters based on the performance calibration results, and determine the physical parameter selection results based on the physical parameters.
[0059] In one possible implementation, physical parameters are determined based on performance calibration results, and physical parameter selection results are determined based on physical parameters, including: determining weight physical parameters and dimensional physical parameters when the performance calibration results meet the requirements; and determining physical parameter selection results based on physical parameter boundaries, weight physical parameters, and dimensional physical parameters.
[0060] In practical applications, see Figure 2 After completing the initial selection step, the next step involves selecting physical parameters such as weight and dimensions. These parameters are chosen based on the product's maximum permissible weight and size requirements. If the weight and dimensions do not meet the requirements, the process iterates back to the initial step for a new selection.
[0061] Step 104: Verify the environmental test indicators based on the physical parameter selection results, and determine the indicator verification results.
[0062] In one possible implementation, environmental test index verification is performed based on the physical parameter selection results, and the index verification results are determined. This includes: if the physical parameter selection results meet the requirements, environmental adaptability testing is performed to determine the environmental adaptability capability; wherein, the environmental test capability includes force environment, thermal environment and magnetic environment; and the selection is based on the environmental adaptability capability to determine the index verification results.
[0063] In practical applications, see Figure 2 Then, the third step is to select environmental adaptability capabilities. First, based on the needs of spaceflight, environmental adaptability packages are selected in the order of force, heat, magnetism, and other environments.
[0064] When capabilities fail to meet requirements, or when environmental adaptability affects basic measurement indicators, verification of test indicators under that environment should be conducted. If the requirements of the first step cannot be met, the first step should be restarted. If the first step cannot provide solutions, such as vibration isolation, thermal coating, temperature control, or magnetic protection, then the impact of the solutions should be comprehensively considered, and the second step of the process should be restarted.
[0065] In one possible implementation, environmental adaptability testing is conducted, including: environmental adaptability testing of the force environment through sinusoidal vibration tests, random vibration tests, and shock tests; environmental adaptability testing of the thermal environment through thermal cycling tests, storage tests, and thermal vacuum tests; and environmental adaptability testing of the magnetic environment through a constant magnetic field environment.
[0066] In practical applications, mechanical environment adaptability testing is required: the sensor should be able to withstand the mechanical environment of the spacecraft launch phase without compromising its performance. Mechanical environment testing is conducted through sinusoidal vibration tests, random vibration tests, and shock tests. The test magnitude and frequency band are set according to the actual environment experienced. During acceptance and qualification testing, whether the sensor is powered can be determined based on its operating state during actual launch. Shock tests should be conducted using shock response spectrum control. Before and after testing, the sensor's condition is checked to ensure product integrity.
[0067] Furthermore, thermal environment adaptability testing: The thermal environment adaptability testing of the sensor includes thermal cycling testing, storage testing, and thermal vacuum testing. Except for storage testing, the sensor should be in operational condition during the testing. The testing includes acceptance-level testing and qualification-level testing, and the test conditions are designed based on the actual temperature environment during on-orbit operation. The rate of temperature change should also be taken into account in the setting of the test conditions.
[0068] Furthermore, magnetic environment adaptability test: The sensor should undergo a magnetic environment adaptability test during the prototype stage. The sensor is placed in a constant magnetic field environment for testing to verify the changes in the sensor response when the magnetic field is turned on and off.
[0069] In one possible implementation, environmental adaptability testing also includes conducting radiation tests and EMC tests.
[0070] In practical applications, other environmental adaptability tests may also be included, which generally encompass radiation testing and EMC testing. These two types of tests are typically conducted during the prototype stage. When conducting radiation testing, the radiation exposure can be calculated based on the product's service life to perform equivalent testing. EMC testing requires simulating not only the operating conditions under electromagnetic interference but also the emission to the outside environment during operation.
[0071] Step 105: Verify the aerospace process based on the indicator verification results and determine the aerospace process verification results.
[0072] In one possible implementation, aerospace process verification is performed based on the indicator verification results, and the aerospace process verification results are determined, including: determining the on-orbit working environment if the indicator verification results meet the requirements; and performing aerospace process verification based on the on-orbit working environment to determine the aerospace process verification results.
[0073] In practical applications, see Figure 2 Finally, once the adaptability tests in step three meet the requirements, the fourth step of comprehensive testing and verification will be conducted. This fourth step should include all on-orbit operational procedures and should be carried out according to standard aerospace protocols.

The method includes: determining resolution and range parameters; determining a target sensor based on these parameters; calibrating the noise performance of the target sensor and determining the calibration results; determining physical parameters based on the calibration results; determining physical parameter selection results based on these physical parameters; verifying environmental test indicators based on the physical parameter selection results and determining the verification results; and verifying aerospace procedures based on the verification results and determining the aerospace procedure verification results. This enables the ground-based testing and evaluation of high-precision aerospace sensors, ensuring their reliability in orbit.
