Problems solved by technology

In this case, the layout of the data acquisition equipment will be very limited
[0004] In addition, the current distribution of remote sensing satellite baseband data is usually carried out after receiving, and the remote sensing satellite baseband data files are sent to a fixed FTP server by using the FTP command, so that it is impossible to provide safe and effective data for local or remote processing devices at the same time. Distribution service of real-time remote sensing satellite baseband data

Abstract

The invention provides a system for acquiring and distributing baseband data of a remote sensing satellite. The system comprises a task management device, a data acquiring device, a data storage device and a data distributing device. When detecting a data acquisition task list, the data acquiring device acquires baseband data of the remote sensing satellite and corresponding time code information thereof from the remote sensing satellite by a fully digital demodulator via the network. The data distributing device distributes the required baseband data of the remote sensing satellite to user equipment after receiving data distribution requests of the user equipment. By the aid of the system, the baseband data of the remote sensing satellite can be acquired in real time via the network, and meanwhile, uniform data distributing services can be provided to rear-end equipment via the network, and accordingly, limits of ECL (emitter-coupled logic) signal transmission distance and special acquisition cards are eliminated.

Description

technical field [0001] The invention relates to the field of remote sensing satellite baseband data collection and distribution, and more specifically, to a remote sensing satellite baseband data collection and distribution system and method. Background technique [0002] The receiving and recording of remote sensing satellite data is the first link in the process of remote sensing satellite data acquisition and processing. Remote sensing satellite digital baseband signals usually include data signals and clock signals. Traditionally, the input method of remote sensing satellite digital baseband signal acquisition is ECL signal. After the ECL signal enters the recording device, a dedicated data acquisition board is used to complete the serial-to-parallel conversion of the ECL signal, and then write the baseband data signal through the PCI bus. Into the data storage device (for example, memory), thereby generating the binary remote sensing satellite raw data required by the ...
