Problems solved by technology

When each orbit measuring station transmits a signal, it is easy to expose the position of the orbit measuring station, and it is easy to be attacked or destroyed in wartime. For this reason, the present invention proposes a new method for improving the concealment of the orbit measuring system and improving the anti-strike and anti-destruction capabilities.

Embodiment Construction

[0019] Please refer to Figure 3 to Figure 5 , the present invention installs a transmitting station and more than three ground satellite receiving stations in the ground segment. The system of the present invention only requires one orbit measuring station to transmit signals, and other stations receive the signals of the transmitting station at the same time. In principle, other stations are only required to have the receiving function. In addition to common equipment such as antennas, low-noise amplifiers (LNAs), receivers, and power supplies, the receiving station must also be equipped with high-precision atomic clocks as frequency and time references, and the accuracy is required to be better than 1×10 -12 second. With a high-precision clock and using a high-precision ranging code, high-precision time difference measurement and high-precision distance measurement can be realized through pseudo-code correlation.

[0020] This system must accurately measure the geographic...

Abstract

The present invention provides a repeater one-station-emitting and multiple-station-receiving secondary planet track detecting method which relates to deep-space tracking technique. Wherein only one ground track detecting station capable of receiving and emitting signals are provided, and other ground track detecting stations are receiving stations. In wartime, emitting station can change according to needs, even emitting in movement without losing precision, to ensure the concealment of whole system, avoid the track detecting station is discovered by enemy efficiently, and enhance the anti-destruction capability and anti-jamming capability of whole system.

Description

Technical field: [0001] The invention discloses a transponder type one-station transmission and multiple-station satellite orbit measurement method, relates to the technical field of deep space tracking, and is suitable for satellite orbit measurement technology and deep space aircraft orbit measurement. Background technique [0002] On December 30, 2003, Li Zhigang and others applied for the "Orbit Determination Method for Transponder Satellites", which was approved on July 5, 2006 (patent application number: 200310102197.1). This is a method for orbit determination of satellites using transponders, and is suitable for orbit determination of satellites or spacecraft equipped with transponders. Its characteristic is that each station realizes the precise orbit measurement of satellites or spacecraft by receiving the transmitted signal and measuring the time interval of the signal from the transmitting station to the satellite or other measuring stations. This method needs t...
