Method for Processing and Assessing the Integrity of GNSS Position Information - A simplified explanation of the abstract
This abstract first appeared for US patent application 18496876 titled 'Method for Processing and Assessing the Integrity of GNSS Position Information
Simplified Explanation
The method described in the patent application involves processing and assessing the integrity of GNSS position information by following these steps:
- Receiving GNSS signals and determining a preliminary GNSS position.
- Checking the preliminary GNSS position against a first condition and discarding it if the condition is met.
- Ascertaining the integrity of the GNSS position based on an integrity criterion determined in the field, excluding positions that satisfy the first condition.
- Outputting the preliminary GNSS position as a verified GNSS position if it was not discarded in the previous step.
Potential Applications: - Navigation systems - Autonomous vehicles - Surveying and mapping
Problems Solved: - Ensuring the accuracy and reliability of GNSS position information - Avoiding errors in navigation and location-based services
Benefits: - Improved accuracy of location data - Enhanced reliability of GNSS positioning - Increased confidence in navigation systems
Potential Commercial Applications:
- Improving GNSS Position Integrity for Navigation Systems
Possible Prior Art: There are existing methods for verifying GNSS position information, but this specific approach of discarding positions that meet certain conditions and assessing integrity based on excluded data may be novel.
Unanswered Questions:
- How does this method compare to existing GNSS integrity assessment techniques?
This article does not provide a direct comparison with other methods currently used in the industry.
- What specific integrity criteria are used to assess GNSS position information in the field?
The patent abstract mentions an integrity criterion determined in the field, but the exact details of this criterion are not elaborated on in the provided information.
Original Abstract Submitted
A method for processing and assessing the integrity of GNSS position information incudes (a) receiving GNSS signals and ascertaining a preliminary GNSS position, (b) checking the preliminary GNSS position ascertained in step (a) against a first condition and discarding the preliminary GNSS position if the first condition is satisfied, (c) ascertaining the integrity of the GNSS position based on an integrity criterion ascertained in the field which was determined excluding GNSS positions that satisfy the first condition, and (d) if the GNSS position was not discarded in step (b), outputting the preliminary GNSS position as a verified GNSS position.
