Modular Mobile Earth Stations With Leader Switching for Blocked Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing satellite communication systems with mobile earth stations (MESs) face challenges in maintaining reliable communication due to obstacles blocking line-of-sight links, leading to temporary unsatisfactory signal quality, especially when relying on a single MES for communication.
Innovation Solution
A system of modularized MESs operates in a leader-follower configuration, where auto-negotiation determines a leader MES that manages combining and dividing satellite-related signals among multiple MESs, utilizing digital and analog beamforming techniques to enhance signal quality and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single MES is used for satellite communication, then device complexity is reduced, but communication reliability deteriorates due to obstacles blocking line-of-sight links
Solution Approach 1:
The system divides the communication function across multiple MES units distributed at different locations. Each MES can independently communicate with satellites, and they work together as a coordinated group. This segmentation allows the system to maintain communication reliability even when some MES units are blocked by obstacles, as other units can continue transmitting and receiving signals.
Solution Approach 2:
Multiple MES units are merged into a coordinated communication system where they function as a unified group. The MESs combine their communication capabilities through coordinated transmission and reception, effectively creating a distributed antenna system that improves overall reliability while managing complexity through standardized interfaces and protocols.
2Reliability
If multiple MESs operate independently, then communication reliability is improved through redundancy, but system coordination complexity increases
Solution Approach 1:
The system implements dynamic role assignment where MES units can switch between leader and follower modes based on real-time conditions. The leader MES coordinates with satellites and manages the communication group, while follower MESs provide redundant communication paths. This dynamic structure allows the system to maintain reliability through redundancy while managing coordination complexity through clear hierarchical roles.
Solution Approach 2:
The MES units perform self-configuration and self-coordination through automated protocols. When MESs are deployed, they automatically negotiate roles, establish communication links, and coordinate their operations without requiring complex external management. This self-service capability reduces coordination complexity while maintaining the reliability benefits of multiple independent units.
3Reliability
If MESs are fixedly mounted to improve stability, then communication reliability improves, but adaptability to different locations and configurations deteriorates
Solution Approach 1:
Each MES unit is designed as a universal, self-contained communication node that can operate independently at any location. The standardized interfaces and protocols allow MESs to be deployed in various configurations and environments. This universality provides adaptability to different locations while maintaining communication stability through consistent operational procedures and redundant pathways.

AI summary
A communication system includes a plurality of MESs arranged at different locations and operating as a unit to communicate with one or more satellites. One of the MESs is configured in a leader mode and each remaining MES of the MESs is configured in a follower mode based on a result of an auto-negotiation. In the leader mode, the one MES manages combining/dividing of satellite-related signals communicated between the one MES and each of the remaining MESs.
