Master GNSS Receiver Signal Distribution for Anti-Jam Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and inefficiency of installing multiple anti-jam antenna systems for global navigation satellite system (GNSS) receivers in surveillance or military vehicles, as each system requires its own antenna, leading to increased expenses and complexity.
Innovation Solution
A single master GNSS receiver uses a single anti-jam antenna system to generate a trusted GNSS signal, which is then distributed to multiple GNSS receivers via a coaxial link, allowing them to recover positioning, navigation, and timing information, thereby eliminating the need for individual anti-jam antennas and reducing installation costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple anti-jam antenna systems are installed, one for each GNSS receiver, then each system can independently receive and process GNSS signals with anti-jam capabilities, but the cost and installation complexity increase significantly
Solution Approach 1:
The patent combines multiple GNSS receivers into a single receiver unit that can serve multiple systems. Instead of installing separate anti-jam antenna systems for each receiver, one integrated receiver processes GNSS signals and distributes the processed data to multiple systems, thereby reducing the number of antennas from multiple to a single unit while maintaining anti-jam capabilities across all connected systems.
Solution Approach 2:
The integrated GNSS receiver is designed to perform multiple functions simultaneously - it receives and processes GNSS signals with anti-jam capabilities, generates positioning data, and distributes this data to multiple different systems (navigation, communication, targeting). This universal receiver replaces multiple specialized receivers, each requiring its own dedicated antenna, thereby reducing overall system complexity while maintaining reliability.
2Ease of manufacture
If a single master GNSS receiver is used to generate signals for multiple receivers, then cost is reduced, but the method complexity increases due to signal generation and distribution requirements
Solution Approach 1:
The patent introduces a signal distribution network as an intermediary between the master GNSS receiver and multiple slave receivers. The master receiver generates processed GNSS signals and positioning data, which are then transmitted through coaxial cables and distribution hubs to multiple slave receivers. This intermediary distribution system simplifies the overall architecture by centralizing signal generation while providing standardized interfaces to multiple systems, reducing installation complexity despite adding distribution infrastructure.
3Reliability
If multiple independent GNSS receiver systems are installed, then each system has independent signal processing capability, but the number of components and installation requirements multiply
Solution Approach 1:
The patent merges multiple independent GNSS receiver systems into a single master receiver that processes signals centrally. Instead of having multiple separate receivers each requiring their own antenna, the system uses one master receiver with a single antenna to process GNSS signals and distribute the processed data to multiple slave receivers, thereby reducing the quantity of antenna components from multiple to one while maintaining signal processing capability across all systems.

AI summary
Embodiments of the inventive concepts disclosed herein are directed to systems and methods for managing global navigation satellite system (GNSS) receivers. A master GNSS receiver can receive, via an antenna system, a GNSS signal. The master GNSS receiver can determining, using the received GNSS signal, information including positioning, navigation and timing (PNT) or positioning, velocity and time (PVT) information. The master GNSS receiver can generate a master GNSS signal using a signal generator and the determined information, and a message indicating that the master GNSS signal is a trusted GNSS based signal. The master GNSS receiver can communicate, via a distribution hub, the generated master GNSS signal and the message to a plurality of GNSS receivers co-located with the master GNSS receiver, for recovering the PNT or PVT information from the master GNSS signal.
