Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current satellite communication systems face inefficiencies in optimizing communication capacity distribution based on time- and location-dependent communication needs, leading to suboptimal coverage and potential gaps in service.
Innovation Solution
The system dynamically adjusts the orientation of satellite antennas to redirect communication capacity from areas with low needs to areas with high demands, using a control algorithm that calculates and reallocates capacity based on predicted communication volumes, ensuring continuous and efficient coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If satellite antennas are oriented towards the center of the earth to provide uniform coverage, then coverage area is maximized, but communication capacity cannot be optimized for time- and location-dependent needs
Solution Approach 1:
The patent applies dynamics by enabling satellite antennas to change their orientation dynamically based on time- and location-dependent communication needs. Instead of fixed downward orientation, the system adapts beam directions in real-time to redirect capacity toward areas with higher demand, thus optimizing communication capacity while maintaining coverage reliability through controlled dynamic adjustment.
2Adaptability or versatility
If antenna orientation is fixed towards the center of the earth, then system complexity is minimized, but the system cannot respond to changing communication requirements
Solution Approach 1:
The patent applies preliminary action by using forecasted communication data to proactively adjust antenna orientations before peak demand periods occur. The control algorithm processes historical and predicted communication patterns to pre-position satellite beams in optimal directions, enabling the system to respond to changing requirements without requiring complex real-time reactive control mechanisms.
Solution Approach 2:
The patent implements feedback by continuously monitoring actual communication data and comparing it with forecasted values. This feedback loop allows the control algorithm to refine future antenna orientation decisions based on observed patterns, improving adaptability while managing system complexity through iterative optimization rather than requiring overly complex deterministic control systems.
3Reliability
If communication capacity is redistributed to areas with high demand, then service quality in those areas improves, but coverage areas with low demand may experience capacity reduction
Solution Approach 1:
The patent applies local quality by enabling different satellite beams to serve different geographical areas with differentiated service levels. Based on forecasted communication needs, the system directs higher capacity beams toward areas with high demand while maintaining adequate service in low-demand areas. This localized optimization improves service quality where needed most while preserving overall system productivity through efficient capacity distribution.

AI summary
The invention relates, inter alia, to a satellite communication system (20) for mobile satellite communication, comprising: several communication satellites (30, 50), each configured to handle a predetermined number of communication connections to and from satellite phones simultaneously, each communication satellite having the following features: an antenna (34, 51) oriented towards the Earth's surface, a control device (31) configured to align the antenna (34) to a predetermined reference point with respect to the Earth upon response to a first control signal, regardless of the position of the respective communication satellite (30), and further configured to align the antenna (34) upon response to a second control signal assigned to the respective communication satellite (30, 50),which depends on a time- and location-dependent need for simultaneous communication links and on the time-dependent position of the respective communication satellite (30, 50), to deliberately change the orientation of the antenna (34) relative to the orientation of the antenna (34) towards the specified reference point.
