[0028] The present application provides a method for processing position jump errors of astronomical star measurement correction during astronomical / inertial position combined navigation, thereby enabling rapid tracking of astronomical / inertial position combined navigation on the position measurement information of the guide antenna, and improving the stability of the combined navigation filter. The astronomical / inertial position combined navigation is based on Kalman filter theory, constructing system equations using the inertial navigation error equation, and using the position information of the guide antenna device as the measurement. The basic method of Kalman filter combined navigation can be found in the public literature and will not be described in this application. The present application mainly relates to the Kalman filter measurement information processing method and the measurement update execution logic.
[0029] like Figure 1 As shown, the method for processing position jump errors of astronomical / inertial position combined navigation astronomical star measurement correction in the present application includes the following steps: Step a) Astronomical star position correction and identification.
[0030] remember k The longitude and latitude of the sky guide at this moment are 、 .calculate k The longitude and latitude position of the sky guide at the moment k The relative longitude and latitude position difference at time -1: (1) (2) Where, and They are k The relative longitude and latitude position difference of the satellite at that moment; and They are k The longitude and latitude position of the sky guide at any moment; and They are k -1 The longitude and latitude position of the antenna at time calculate k The relative positioning error value of the time-domain guide for: (3) Where, for k The comprehensive relative positioning error value of the antenna guide at this moment.
[0031] Based on the fact that the position error of the sky guide is discontinuous and jumps during star measurement, the threshold value of the error change is measured before and after. Identify the correction of the satellite observation: (4) Where, flag It is the star measurement correction flag, 1 means star measurement correction, 0 means no star measurement correction.
[0032] Step b) Calculation of astronomical / inertial integrated navigation measurements.
[0033] remember k The longitude and latitude positions calculated by inertial navigation at the moment are and ,but k The moment-to-moment combined navigation measurement is: (5) Where, for k Time astronomical / inertial combined navigation measurement, and They are k The longitude and latitude position of the antenna at all times.
[0034] Step c) performing inertial navigation position correction based on the quantitative measurement and star measurement correction mark.
[0035] If the star measurement correction flag is 1, the inertial navigation position is directly corrected using the measurement: (6) After correction, Set to 0, and then perform Kalman filter time update and measurement update.
[0036] If the star measurement correction flag is 0, the Kalman filter time update and measurement update are directly executed.
[0037] Astronomy / Inertial combined navigation Astronomy star measurement correction position jump error processing effect is as follows Figure 2 As shown in the figure, when the error of the guide antenna position measurement information jumps, the astronomical / inertial combined navigation positioning error quickly tracks the change of the guide antenna position measurement. When there is no astronomical star measurement afterwards, the navigation information output by the combined filter has no overshoot oscillation, and the combined navigation filter is stable.
[0038] Based on the fact that the position information of the guide antenna is discontinuous and jumps during astronomical correction, this application identifies astronomical star corrections and directly corrects the inertial navigation position using the filtered value measured at the time of correction, thus achieving rapid tracking of the guide antenna position measurement information by astronomical / inertial position combined navigation. This method solves the problem that the error jumps in the guide antenna position measurement information are non-Gaussian white noise, which prevents the Kalman filter from quickly tracking the measurement changes and thus causes overshoot and oscillation of the navigation information output by the filter, effectively improving the stability of the combined navigation filter.
[0039] Specifically, the method for processing the position jump error of the astronomical / inertial position combined navigation astronomical star measurement correction in the embodiment of the present application completes the astronomical guide star measurement correction identification and the combined navigation measurement calculation according to steps a) and b) of the above technical solution; according to step c), the combined navigation realizes the rapid tracking of the astronomical guide position measurement information. The implementation flow chart is as follows: Figure 1 The specific steps are as follows: Step 1: Record k -1 moment longitude and latitude position information of the satellite 、 , update the current k Time-of-day longitude and latitude location information 、 , calculated according to formula (1) to formula (3) k The relative positioning error value of the time-domain guide .
[0040] Step 2: Set the threshold for the change in measurement error before and after = 0.1 nautical mile, and determine the star measurement mark according to formula (4) flag The value of Step 3: Get the current k Time inertial navigation longitude and latitude position and , calculate the current k Time-combined navigation measurement .
[0041] Step 4: If the star measurement correction flag is 1, measure the amount according to formula (6) Directly calibrate the inertial navigation position. If the star calibration flag is set to 0, the Kalman filter time update and measurement update are executed directly.
