Embodiment Construction

[0057] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0058] The tracking visible report is defined as a set of time series recording the start and end moments of the visible arc segment of the inter-satellite and satellite-ground Ka antenna (or array), mainly including the node ID of a certain link and the start and end time of each arc segment.

[0059] A unified description model for the position and attitude of the space-borne Ka phased array antenna and the ground-based Ka phased array antenna.

[0060] Key parameters such as the position, attitude, and beam angle of the Ka antenna determine its visible airspace range in space. Whether it is a spaceborne Ka antenna or a ground-based Ka antenna, it can be considered as an observation node in space. Therefore, a set of unified model parameters is proposed to describe its position and attitude in space. The position and attitude model paramete...

Abstract

The invention discloses a Beidou Ka complex phased-array antenna tracking visible report generation algorithm. The algorithm is specifically implemented according to the following steps: 1, establishing a position attitude model about a satellite-borne Ka phased-array antenna and a ground-based Ka phased-array antenna; 2, proposing an inter-satellite visibility judgment algorithm; and 3, proposinga tracking visible report generation algorithm. According to the method, the mutual visibility between the stars is calculated through the satellite space geometrical relationship, and then the star-star visibility report is generated. Through complex beam forming of the Ka phased-array antenna, a satellite-earth visible report is obtained. Through the visible report generation algorithm, omnibearing tracking of a ground Ka station on a Beidou satellite can be achieved, and the method has the advantages of being simple, practical and high in engineering realizability.

Description

technical field [0001] The invention belongs to the technical field of satellite navigation tracking measurement and control, in particular to a generation algorithm for Beidou Ka complex phased array antenna tracking visible report. Background technique [0002] The traditional tracking and control of satellites is based on the "station-satellite" tracking mode, "station" refers to the ground tracking station, and "star" refers to the satellite. In the measurement and control task, it is necessary to formulate the measurement and control plan according to the station tracking and visible reports. Tracking and visibility reporting refers to the use of the forecasted satellite orbit (spatial position) to determine whether the ground station and the satellite are visible to each other under the condition of accurate station site conditions, and to calculate the satellite entry and exit time, tracking time period, etc. . Traditional ground-based S-band measurement and control...
