Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems for satellite networks lack efficient, secure, and reliable protocols for multi-tenant satellite systems, particularly in ground station-to-satellite and satellite-to-satellite communications, which are mission and radio technology agnostic, and do not support end-to-end application layer communication interfaces.
Innovation Solution
A space communication protocol enabling multi-tenant satellite systems through application containerization, using a specially programmed agent in satellites and ground stations to manage communication links, support multi-tenant applications, and implement end-to-end security, quality of service, and neighbor-aware intersatellite networking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing communication systems are used for satellite networks, then basic communication functionality is provided, but efficient and secure protocols for multi-tenant satellite systems are lacking
Solution Approach 1:
The communication protocol is segmented into multiple layers including application layer, transport layer, and network layer, with each layer handling specific functions. This segmentation allows the protocol to provide reliable communication while simultaneously supporting multi-tenant applications through dedicated application layer interfaces.
Solution Approach 2:
The communication protocol is designed as a universal system that can serve multiple satellite operators and applications simultaneously. It provides end-to-end communication interfaces that are agnostic to specific missions or radio technologies, enabling a single protocol to handle diverse multi-tenant requirements while maintaining reliability.
2Adaptability or versatility
If mission and radio technology agnostic protocols are implemented, then versatility is improved, but end-to-end application layer communication interfaces are not supported
Solution Approach 1:
The protocol introduces a new dimension at the application layer that sits above the traditional transport and network layers. This additional layer provides mission and radio technology agnostic interfaces without complicating the lower layers, as each layer operates independently with well-defined interfaces.
3Reliability
If secure communication is implemented for multi-tenant systems, then security is improved, but communication efficiency may be reduced
Solution Approach 1:
Security measures such as authentication and encryption are established through preliminary handshaking protocols before actual data transmission begins. Once security is established, data can flow efficiently without repeated security checks, maintaining both security and communication efficiency.
4Productivity
If neighbor-aware intersatellite networking is implemented, then resource sharing efficiency is improved, but system complexity increases
Solution Approach 1:
Satellites automatically discover and register their capabilities with neighboring satellites through automated protocols. The network self-organizes routing paths and resource allocations based on declared capabilities, eliminating the need for complex centralized management while achieving efficient resource sharing.

AI summary
A satellite includes a communication link interface and at least one processor and at least one memory. The at least one processor and the at least one memory are configured to support multiple tenant applications in a multi-tenancy cloud-computing environment, and two or more of the multiple tenant applications establish isolated communication link channels with a ground station utilizing the communication link interface.
