GLOBAL NAVIGATIONAL SATELLITE SYSTEM (GNSS) INTERFERENCE DETECTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18301449 titled 'GLOBAL NAVIGATIONAL SATELLITE SYSTEM (GNSS) INTERFERENCE DETECTION
The abstract describes a system for detecting interference in Global Navigation Satellite Systems (GNSS) by creating a satellite tracking table for an Access Point (AP) and comparing expected satellite parameters with derived satellite parameters from received signals.
- A satellite tracking table is created for an AP, listing available GNSS satellites and their expected parameters.
- Derived satellite parameters from received signals are compared with expected parameters in the tracking table.
- Interference events are identified when derived parameters differ from expected parameters by a predetermined amount.
Potential Applications: - Enhancing the reliability and accuracy of GNSS systems. - Improving the performance of location-based services. - Enhancing the security of GNSS signals against interference.
Problems Solved: - Detecting and mitigating interference in GNSS systems. - Ensuring the integrity of location data provided by GNSS signals.
Benefits: - Increased accuracy and reliability of location-based services. - Enhanced security against interference in GNSS signals. - Improved overall performance of GNSS systems.
Commercial Applications: Title: "Enhanced GNSS Interference Detection System" This technology can be utilized in industries such as transportation, logistics, agriculture, and surveying for precise location tracking and navigation purposes. It can also be integrated into consumer devices for improved location-based services.
Questions about GNSS Interference Detection: 1. How does this system improve the accuracy of location data provided by GNSS signals? - The system compares derived satellite parameters with expected parameters to detect interference, ensuring the integrity of location data. 2. What are the potential implications of interference in GNSS signals for various industries? - Interference in GNSS signals can lead to inaccuracies in location tracking, affecting industries such as transportation, agriculture, and surveying.
Original Abstract Submitted
Global Navigation Satellite System (GNSS) interference detection may be provided. A satellite tracking table for a first Access Point (AP) may be created. The satellite tracking table may include a listing of a plurality of satellites of a Global Navigation Satellite System (GNSS) available for the first AP and expected satellite parameters for each of the plurality of satellites. A derived satellite parameter may be determined from a received GNSS signal. The derived satellite parameter may be compared with an corresponding expected satellite parameter. The corresponding expected satellite parameter may be determined from the satellite tracking table. An interference event may be determined when the derived satellite parameter differs from the corresponding expected satellite parameter by at least a predetermined amount.
