Problems solved by technology

This kind of traditional information chain, due to the complex transmission process between the satellite and the ground, many information assurance links, large delays, and narrow real-time coverage, will reduce the real-time and effectiveness of the payload data on the star. If the wartime link is destroyed , it will break the information chain and cause huge losses
On the other hand, when the effective data rate is low, due to the single method of data transmission to the ground, the data transmission subsystem has to be used for transmission, which wastes the energy of the whole star

Embodiment Construction

[0030] The invention adopts a mature modular structure form, and the equipment body is composed of four sub-modules, and the size of the body is 170mm×78mm×130mm. The sub-modules are overlapped, and the sub-modules are connected in series by 4 M5 screws. The outer surface is black anodized, and the aluminum color of the installation surface is conductive and oxidized. The modules are fastened together with screws, which can reduce the contact resistance. Good for shielding. In order to meet the requirements of anti-radiation, the basic wall thickness of each part is 1.5mm. The design avoids sharp corners, avoids stress concentration, and improves the strength of parts. The connection of the internal signals of each sub-module is mainly connected by the J3C printed board electrical connector. The connection of external low-frequency and high-frequency signals is realized by the external electrical connector installed on each module. The tactical distribution unit is installed...

Abstract

The invention relates to a data broadcasting distribution unit for small satellites. The data broadcasting distribution unit comprises a power module, a baseband processing module, an encryption module and a radio frequency module. The data broadcasting distribution unit provided by the invention adopts the design idea of integration, integration and miniaturization, and satisfies the practical demands of small satellite platforms for small load, light weight and low power consumption.

Description

technical field [0001] The invention relates to a data broadcasting and distributing unit, in particular, based on the weight, volume and power consumption limitations of a small satellite platform, real-time, efficient and large-scale broadcasting and distributing of on-board data. Background technique [0002] The on-board payload data transmission to the ground plays a very important role in realizing the on-orbit function of the satellite. In the reception and application of satellite payload data, the traditional path has been used, that is, the satellite data transmission subsystem transmits the data to the ground, or the relay satellite receives the satellite data transmission data and forwards it to the ground, and transmits the payload data to the ground. Station, processed by the ground station and then forwarded to the user terminal. This kind of traditional information chain, due to the complex transmission process between the satellite and the ground, many info...
