Embodiment Construction
[0041] The present invention is described in detail below in conjunction with accompanying drawing:
[0042] The present invention provides a method for evaluating the measurement performance of the short-baseline relative orbital perturbation gravity field, which establishes the relationship between the measurement performance of the short-baseline relative orbital perturbation gravity field and the mission parameters in an analytical form. Therefore, as long as the gravity field is obtained Measure the task parameters and input them into the analytical relational formula to quickly analyze the measurement performance of the gravity field, including: effective order of gravity field measurement, geoid accuracy, gravity anomaly accuracy, etc., with fast analysis speed and accurate analysis results The advantage of high precision overcomes the shortcomings of the traditional numerical simulation method, such as long calculation time and the inability to obtain the influence of m...
