SATELLITE SIGNAL ENVIRONMENT DETERMINATION AND/OR POSITION ESTIMATE SELECTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17390923 titled 'SATELLITE SIGNAL ENVIRONMENT DETERMINATION AND/OR POSITION ESTIMATE SELECTION
Simplified Explanation
The patent application describes a method for estimating the position of a user equipment (UE) based on positioning signals. The method includes the following steps:
- Receiving one or more positioning signals.
- Determining if the UE is in line-of-sight to fewer than a certain number of positioning signal sources.
- Estimating the UE's position using a first position estimating process and first measurements of the positioning signal(s).
- Estimating the UE's position using a second position estimating process and second measurements of the positioning signal(s). The second process uses a different parameter value than the first process.
- Reporting a position estimate based on either the first or second position estimate hypothesis, depending on the number of positioning signal sources in line-of-sight.
Potential applications of this technology:
- Location-based services: The method can be used in applications that require accurate positioning information, such as navigation systems, asset tracking, and emergency services.
- Indoor positioning: The method can be applied in indoor environments where line-of-sight to positioning signal sources may be limited, such as in shopping malls or airports.
Problems solved by this technology:
- Limited line-of-sight: The method addresses the challenge of accurately estimating the position of a UE when it is not in line-of-sight to a sufficient number of positioning signal sources.
- Parameter optimization: By using different parameter values in the position estimating processes, the method aims to improve the accuracy of the position estimates.
Benefits of this technology:
- Improved positioning accuracy: By utilizing multiple position estimating processes and measurements, the method aims to provide more accurate position estimates for UEs.
- Flexibility: The method allows for the use of different parameter values, providing flexibility in optimizing the position estimating processes for different scenarios.
Original Abstract Submitted
A method includes: receiving one or more positioning signals; determining that a UE is line-of-sight to fewer than a threshold number of positioning signal sources; determining a first position estimate hypothesis for the UE using a first position estimating process and one or more first measurements of the positioning signal(s); determining a second position estimate hypothesis for the UE using a second position estimating process and one or more second measurements of the positioning signal(s), wherein the second position estimating process uses a second parameter value of a parameter and the parameter is absent from the first position estimating process or has a first parameter value that is different from the second parameter value; and reporting a reported position estimate based on the first position estimate hypothesis or the second position estimate hypothesis in response to the UE being line-of-sight to fewer than the threshold number of positioning signal sources.
