Embodiment Construction

[0019] In this example, the measured Chang'e-2 (CE-2) USB ranging and speed measuring data are used, and the multi-satellite parallel high-precision orbit calculation software system (PASAX) independently developed by the State Key Laboratory of Aerospace Dynamics is used. The specific implementation method as follows:

[0020] Step 1: Refer to figure 1 , taking an uplink measurement and control station in the CE-2 project as the transmitting station R, and a downlink measurement and control station as the receiving station S, set the midpoint of the RS connection as the virtual station M, and calculate the coordinates of the M station. The actual observations are from 10:00 on May 1, 2011 to 12:00 on the same day. Station R transmits uplink, forwards through CE-2, and receives USB distance measurement and speed measurement data downlink at S station. The sampling rate is 5s; prepare for this time period The precise orbit of CE-2 serves as the basis for further calculations. ...

Abstract

The invention discloses a three-way observation data processing method based on a virtual station, and belongs to the field of spaceflight measurement and control. According to the three-way observation data processing method based on the virtual station, firstly, the virtual station M is arranged and is located at the middle point between a launching station S and a receiving station R, a theoretical distance measurement observed quantity rho M based on the virtual station is computed and used for replacing a theoretical distance measurement observed quantity rho C based on the launching station S and the receiving station R, and a theoretical speed measurement observed quantity based on the virtual station is computed and used for replacing a theoretical speed measurement observed quantity based on the launching station S and the receiving station R. The three-way observation data processing method based on the virtual station has the advantages that the theoretical observed quantities based on the virtual station are computed easily and rapidly, meet the requirements for computing accuracy and can be used for replacing the theoretical observed quantities, which are complex in computation, based on the launching station S and the receiving station R; the three-way observation data processing method can be popularized in the field of the spaceflight measurement and control.

Description

technical field [0001] The patent of the invention belongs to the field of aerospace measurement and control, and relates to a data processing method for establishing a measurement model based on a virtual station instead of a dual-station transceiver USB measurement model. Background technique [0002] Over the years, my country's aerospace measurement and control network generally adopts the unified S-band carrier for uplink and downlink to track and measure spacecraft, and the same antenna is mostly used for uplink and downlink transmission and reception. In recent years, with the diversification of mission types, international cooperation and equipment upgrades and other practical problems, some missions have used different USB uplink and downlink antennas (called three-range distance measurement and speed measurement). Different antennas have problems such as different site coordinates, equipment status, integration time and measurement accuracy, which make it impossibl...
