Method for calculating space coordinates of carrier rocket based on telemetry angle measurement data

Abstract

The invention relates to a method for calculating space coordinates of a carrier rocket based on telemetry and angle measurement data. The method comprises the following steps: firstly, ensuring thattelemetering equipment distribution is completed on two sides of a flight route of a carrier rocket, and performing geodetic measurement on the equipment position, so that the geographical position coordinates of the equipment are known; in a spaceflight launch process, tracking the carrier rocket by each telemetering device, so that at least two telemetering devices in different places are in a self-tracking state at the same moment, in the tracking process, continuously sending a measurement angle to the command and control center server by each telemetering device, and the real-time sendingfrequency cannot be too low so as to ensure the data volume required by subsequent step operation; and after the command and control center server receives the measurement angle, calculating the datain real time by the command and control center server through a rendezvous measurement method, and then calculating the space position coordinates of the rocket in combination with a data optimization means. According to the method, a new external ballistic trajectory measurement data backup means is provided for the spaceflight measurement and control system, and the correctness of other external ballistic trajectory measurement data is further verified.

Description

technical field [0001] The invention relates to a method for calculating space coordinates of a launch vehicle, in particular to a method for calculating space coordinates of a launch vehicle based on telemetry angle measurement data. Background technique [0002] In the process of space launch, it is necessary to carry out spatial positioning of the launch vehicle and control its flight trajectory. At present, optical measurement equipment and radio tracking measurement equipment are mainly used for external ballistic measurement to obtain the space position of the rocket. [0003] The launch vehicle is a huge system. It is expensive and has a complex structure. It takes a lot of time and cost to design and produce the load it carries. Therefore, it is necessary to ensure that the space launch process is safe and reliable, and the risk is minimized. . In the process of space launch, multiple devices are often required to participate in tracking and measurement at the same ...
