Description
Technical Field
[0001] This invention belongs to the field of satellite structure technology, and specifically relates to a satellite platform configuration for onboard services. Background Technology
[0002] In recent years, the demand for on-orbit verification of new payloads has been increasing, but traditional methods have many drawbacks, such as: 1. New payloads are launched with the satellite as backups or as carry-on payloads, which is coupled with the satellite development process and has a long cycle; 2. New payloads are launched with the satellite as main payloads, which is costly and risky. If the new payload fails, it will lead to a significant reduction in satellite performance or even scrapping. On the other hand, payloads come in various forms and types, which puts forward a variety of requirements for the platform, including: installation orientation, field of view avoidance, stray light avoidance, micro-vibration / vibration isolation, and ensuring the range of motion of mechanical units.
[0003] Therefore, it is necessary to design a satellite platform configuration that is oriented towards payload services, with the characteristics of being universal and off-the-shelf, in order to reduce the cost of on-orbit verification of new payloads and shorten the development cycle.
[0004] Currently, satellite platform configurations are designed based on overall mission requirements, focusing on the main payload and key operational functions. However, no specific installation space is designed for payloads, making it impossible to meet the installation needs of diverse payload types. This results in low payload efficiency, long development cycles, and high development costs. Summary of the Invention

[0020] The support plate includes a first support plate, a second support plate, a third support plate, and a fourth support plate.

This forms an open structure, with a large payload space above the load-bearing plate, capable of accommodating multiple small payloads or a single large payload. The interior of the load-bearing cylinder provides a suitable mounting environment for optical payloads requiring stray light avoidance, such as optical cameras with networking needs. Depending on the interface of different payload units, only the load-bearing plate and camera mounting plate need to be redesigned, while other structures remain unchanged. The load-bearing plate can be expanded according to the number and volume of payload units, with the dimensions of other components appropriately expanded accordingly. After expansion, the relative positional relationships of the components remain unchanged, and the overall configuration remains the same. This improves development efficiency and reduces R&D costs.
