Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing:

[0024] In the present invention, within a given period of time, the calculation method of the time when the orbital spacecraft changes orbit and the amount of change of the semi-major axis of the orbit comprises the following steps:

[0025] Step 1: In a given period of time [t 0 ,t 1 ](t 1 -t 0 ≥30 days), it is known that the orbiting spacecraft has k TLE elements arranged in ascending order of time, and the semi-major axis of the spacecraft orbit can be calculated according to the number of each TLE element where i=1,2,...k,n i It can be obtained directly from the root number of TLE, μ=3.986×10 5 km 3 / s 2 ;

[0026] Step 2: According to the semi-major axis sequence a in step 1 i , calculate the semi-major axis difference between two adjacent TLE elements, namely Δa i =a i+1 -a i , where i=1,2,...k-1;

[0027] Step 3: According to Δa in Step 2 i (i=1,2,...k...

Abstract

The invention discloses an on-orbit spacecraft orbital transfer detection method based on TLE elements. The method aims at the characteristics of on-orbit spacecraft space orbit operation rules and orbit control. According to the method for calculating the orbital transfer time and the orbital semi-major axis variation of the spacecraft based on the TLE element number, a dynamic orbital transfer threshold value is set, and the problems of orbital change time, orbital variation and multiple orbital transfer recognition in the on-orbit operation process of the spacecraft are effectively solved.

Description

technical field [0001] The invention relates to the field of aerospace measurement and control, in particular to a method for detecting orbit change of an on-orbit spacecraft based on TLE elements. Background technique [0002] With the continuous progress and development of human spaceflight technology and the drastic increase of human space activities, the number of spacecraft operating in orbit shows a trend of continuous and substantial increase. According to the TLE statistics released by NASA, there are currently more than 16,000 space objects in orbit, including more than 4,000 spacecraft in orbit, and the Vanguard1 satellite, which has been in orbit for the longest time, has been in orbit for more than 60 years. Due to different missions and different orbit types, different spacecraft need to adjust their orbits from time to time to ensure the completion of their missions. For the space object management, the information about the orbit change of the spacecraft is u...
