Abstract

The invention provides a relay satellite system forward link detection method and device and electronic equipment and relates to the technical field of communication. The method comprises the following steps: firstly, acquiring task parameter information of a ground terminal station and a locking state of a user relay terminal; meanwhile, coupling a forward radio frequency signal sent by the ground terminal station to obtain radio frequency signals to be detected; and then determining the operation state of the ground terminal station and the operation state of the user relay terminal based onthe task parameter information, the locking state of the user relay terminal and the radio frequency signals to be detected. According to the method, the state of the whole task process of the forward link can be automatically monitored, and once a fault occurs, the fault can be accurately positioned according to the operation states of the current ground terminal station and the user relay terminal, so that the technical problem of poor timeliness of a forward link fault diagnosis method in the prior art is solved.

Description

Technical field [0001] The present invention relates to the technical field of communication, and in particular to a forward link detection method, device and electronic equipment of a relay satellite system. Background technique [0002] In the satellite-satellite-ground loop of the relay satellite system, when the forward link (the link that transmits data from the ground terminal station to the user relay terminal) has abnormal phenomena such as flashing, loss of lock, etc., the abnormal phenomenon usually occurs for a moment. It is fleeting and difficult to capture by common monitoring equipment such as signal spectrum analyzers. Therefore, fault location or fault separation cannot be quickly performed when encountering such abnormal situations. In order to analyze and troubleshoot problems, it is often necessary to take up a large amount of relay satellite resources and ground station equipment resources, and separate and eliminate each possible fault point one by one, which...
