A smart load system and a smart load implementation method based on radio frequency link coupling access

Abstract

The invention provides a smart load system and a smart load implementation method based on radio frequency link coupling access. The system comprises a user radio frequency front end, a feed radio frequency front end, analog-to-digital conversion units, digital-to-analog conversion units, a return link channel processor, a forward link channel processor, a shunt, a combiner, a main function processor, and an auxiliary function processor. According to the invention, the auxiliary function processor bearing temporary tasks can be integrated with the main function processor when not being involved in earlier-stage overall design, and can complete independent tests concurrent with tests of the main function processor, so that the flexibility of the smart load integration solution is improved and the requirement of develop processes for concurrency is met.

Description

technical field [0001] The invention relates to a smart load system coupled and accessed through a radio frequency link and a realization method, belonging to the field of electronic information. Background technique [0002] With the continuous advancement of aerospace technology, a single satellite has the ability to provide multi-functional composite on-orbit services. According to the multi-task requirements of rapid response, smart payload satellites provide flexible and rapid integration capabilities of additional auxiliary functions around the main function of the payload, and its engineering design has become the focus of payload design. In the engineering implementation of smart loads, the task determination of additional auxiliary functions is usually later than the design task of the main function. Therefore, in the case that the design of the main function processor does not consider the design requirements of the auxiliary function, it is necessary to have the ...

Problems solved by technology

However, when it is necessary to temporarily add an auxiliary function processor device with specific additional functions, the digital interface reserved in the early stage may not be able to meet the needs of the new device, and the modification of the existing interface signal will inevitably lead to the transformation of the existing device , including re-demonstration and implementation of design, development, and test programs, extending the development cycle

On the other hand, since it is not convenient to use ready-made standard test equipment for signal testing, it is necessary to disclose interface signals to third parties in order to develop corresponding special test equipment, which brings increased costs and security risks

[0009] Through the novelty search, there is no relevant technical report at home and abroad
