CROSS-FREQUENCY CORRECTION FOR PRECISE POSITIONING - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240094403 titled 'CROSS-FREQUENCY CORRECTION FOR PRECISE POSITIONING
Simplified Explanation
The abstract describes a method for determining the position of a mobile device using correction data associated with pseudorange measurements of GNSS signals sent from satellite vehicles on different carrier frequencies.
- Receiving correction data associated with pseudorange measurements of GNSS signals from satellite vehicles on different carrier frequencies
- Measuring a third GNSS signal on a third carrier frequency to generate a third pseudorange measurement
- Determining the position of the mobile device using the third pseudorange measurement and correction data from the first and second pseudorange measurements
Potential Applications
This technology can be applied in various industries such as navigation, surveying, mapping, and location-based services.
Problems Solved
This technology helps improve the accuracy and reliability of determining the position of a mobile device in challenging environments with signal interference or obstructions.
Benefits

Original Abstract Submitted
an example method performed at a mobile device for determining a position may comprise receiving correction data associated with (1) a first pseudorange measurement of a first gnss signal sent from a satellite vehicle on a first gnss carrier frequency and (2) a second pseudorange measurement of a second gnss signal sent from the satellite vehicle on a second gnss carrier frequency. the method also may comprise measuring a third gnss signal sent from the satellite vehicle and received at the mobile device on a third gnss carrier frequency, to generate a third pseudorange measurement. the method also may comprise determining the position of the mobile device using (a) the third pseudorange measurement of the third gnss signal on the third gnss carrier frequency and (b) the correction data associated with the first pseudorange measurement and the second pseudorange measurement.
