Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication protocols between spacecraft, ground stations, and mission control centers are fragmented and complex, leading to inefficiencies and errors due to the need for numerous translation and interpretation modules, which are not perfect and can introduce delays or errors.
Innovation Solution
A simplified, unified application programmer interface (API) is implemented to coordinate communications, using a discrete set of abstract message definitions and encoding layers to translate and encode messages, allowing for streamlined communication protocols and efficient data transfer between spacecraft, ground stations, and control centers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If custom data communication designs and protocols are implemented for each space mission, then communication compatibility between different spacecraft and ground stations is achieved, but the number of incompatible communication protocols increases and numerous translation and interpretation modules are required
Solution Approach 1:
The patent implements a universal communication framework where a single ground station can communicate with multiple different spacecraft using various protocols simultaneously. The system provides protocol-agnostic interfaces that can handle custom protocols, CCSDS standards, and other space communication protocols through a unified architecture, eliminating the need for separate custom designs for each mission.
Solution Approach 2:
The patent introduces an intermediary communication layer that acts as a mediator between spacecraft and ground stations. This layer includes translation and adaptation capabilities that convert between different protocols without requiring each ground station to implement custom protocol stacks, thereby reducing overall system complexity while maintaining compatibility.
2Adaptability or versatility
If numerous translation and interpretation modules are used to bridge incompatible communication protocols, then communication between different spacecraft and ground stations is enabled, but delays and errors are introduced into communication
Solution Approach 1:
The patent implements a sophisticated intermediary layer that provides intelligent protocol translation and adaptation. This mediator uses context-aware translation algorithms that preserve data integrity while converting between protocols, significantly reducing translation errors and delays compared to traditional modular translation approaches.
Solution Approach 2:
The communication system incorporates feedback mechanisms that monitor translation processes and automatically adjust translation parameters to minimize errors. The system tracks communication quality metrics and uses this feedback to optimize translation accuracy in real-time, thereby maintaining high reliability across protocol conversions.
3Reliability
If ground station and mission control center are placed in remote locations with favorable weather and lack of interference, then communication quality is improved, but housing, education, and human-resource needs become impractical
Solution Approach 1:
The patent divides the communication system into separate functional segments: ground stations optimized for communication quality in remote locations, and mission control centers with full logistical support in accessible locations. The system uses standardized interfaces and automated communication protocols to connect these segmented components, allowing each to be optimized independently for its specific function.
4Adaptability or versatility
If existing SLE Return Channel Frames libraries are used, then standardized communication interfaces are provided, but the interface is overly cumbersome and complex with over 1,000 interface routines
Solution Approach 1:
The patent merges the functionality of over 1,000 separate interface routines into a unified, simplified API that provides the same standardized communication capabilities. The system combines multiple protocol handling, translation, and adaptation functions into integrated components that can be accessed through a small number of straightforward interface calls, dramatically reducing complexity while maintaining full SLE compliance.

AI summary
Disclosed herein are systems, computer-implemented methods, and tangible computer-readable media for coordinating communications between a ground station, a control center, and a spacecraft. The method receives a call to a simple, unified application programmer interface implementing communications protocols related to outer space, when instruction relates to receiving a command at the control center for the ground station generate an abstract message by agreeing upon a format for each type of abstract message with the ground station and using a set of message definitions to configure the command in the agreed upon format, encode the abstract message to generate an encoded message, and transfer the encoded message to the ground station, and perform similar actions when the instruction relates to receiving a second command as a second encoded message at the ground station from the control center and when the determined instruction type relates to transmitting information to the control center.
