Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for synchronizing data in redundant channels of avionics systems in mobile platforms, such as spacecraft and aircraft, rely on flight computers, which can lead to overload and limit their ability to perform other critical tasks.
Innovation Solution
Implementing a synchronization signal generator that produces multiple synchronization signals to synchronize remote interface units, allowing them to execute state machines independently and synchronize redundant data paths between sensor and actuator systems without relying on flight computers.

Engineering Contradiction Analysis
1Reliability
If flight computers generate synchronization commands for redundant channels, then data synchronization is achieved, but flight computer workload increases and other critical tasks are limited
Solution Approach 1:
The synchronization function is extracted from the flight computer and implemented as a dedicated synchronization module. This module independently generates synchronization commands and manages redundant channel synchronization without requiring flight computer intervention, thereby reducing flight computer workload while maintaining reliable data synchronization across all channels.
Solution Approach 2:
A dedicated synchronization module is introduced as an intermediary component between sensors and flight computers. This module handles all synchronization operations for redundant channels, acting as a mediator that eliminates the need for flight computers to generate synchronization commands, thus freeing flight computer resources for other critical tasks.
2Ease of operation
If flight computers handle all synchronization operations, then comprehensive control is maintained, but system complexity and processing load on flight computers increase
Solution Approach 1:
The synchronization system is segmented into independent functional modules: a dedicated synchronization module for generating and managing synchronization commands, and remote interface units for executing them. This segmentation distributes the synchronization functionality across specialized components rather than concentrating it all in the flight computer, reducing overall system complexity while maintaining operational effectiveness.

AI summary
Systems and methods are described for synchronizing data in a mobile platform. In one embodiment, a method for synchronizing data in a mobile platform is provided. The method includes: receiving a first synchronization signal at a first remote interface unit from a signal generator; receiving a second synchronization signal at a second remote interface unit from the signal generator; and executing a synchronization state machine of the first and second remote interface units based on the first and second synchronization signals to synchronize outputs of the first and second remote interface units.
