Electronic Satellite Feed Switcher for Remote Testing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Satellite telecommunication systems require technicians to be physically present to switch between different satellite feeds for testing, limiting remote testing capabilities due to the need for manual feed switching.
Innovation Solution
An electronically controlled feed switcher system using a microcontroller and relays allows remote selection and switching of satellite feeds, enabling remote testing without physical presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual feed switching is used, then the satellite receiver can be tested with different feeds, but a technician must be physically present to switch feeds, limiting remote testing capabilities
Solution Approach 1:
The patent replaces manual mechanical feed switching with an electronically controlled relay system. The relay switcher device receives control signals remotely and automatically switches between different satellite feeds (Eastern Arc, Western Arc, and other feeds) without requiring a technician to be physically present at the receiver location. This substitution of mechanical manual operation with electronic automation resolves the contradiction by enabling remote testing while maintaining ease of operation through automated control.
2Adaptability or versatility
If a technician is physically present to switch feeds, then feed switching can be performed manually, but remote testing options are limited
Solution Approach 1:
The patent introduces a relay switcher device as an intermediary between the control system and the satellite receiver. This intermediary device handles the complex task of feed switching locally at the receiver site, allowing remote control without requiring complex communication infrastructure or high-level system complexity at the remote location. The relay switcher acts as a smart intermediary that simplifies the overall system architecture while enabling remote testing versatility.

Function Achieved in This Case
Enables remote testing of satellite receivers by electronically controlling which feeds are provided to the receiver, reducing the need for manual intervention and allowing for efficient switching between different satellite feeds.
Implementation Method 1
The first relay receives as inputs a first satellite feed and a second satellite feed. The second relay receives as inputs a third satellite feed and an output of the first relay.

AI summary
A feed switcher for a satellite telecommunication system includes a microcontroller, a first relay, and a second relay. The first relay receives as inputs a first satellite feed and a second satellite feed. The second relay receives as inputs a third satellite feed and an output of the first relay. The output of the first relay includes the first satellite feed or the second satellite feed. The microcontroller has a first port and a second port, and the output of the second relay is based on whether at least one of the first port and the second port is open. Therefore, the output of the second relay may be either the output of the first relay or the third satellite feed.
