FAST SENSOR INITIALIZATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17933456 titled 'FAST SENSOR INITIALIZATION
Simplified Explanation
The patent application aims to reduce sensor initialization time for sensors used for Dead Reckoning (DR) positioning during a Global Navigation Satellite System (GNSS) signal outage.
- A UE initiates a first positioning engine based on GNSS signal availability.
- The first positioning engine measures the UE's relative position without ambiguity processing.
- The UE calibrates at least one IMU sensor based on the relative position measured by the first positioning engine.
- The UE performs a positioning calculation via the IMU sensor when the GNSS signal is unavailable.
Potential Applications
This technology could be applied in autonomous vehicles, drones, and other devices that rely on accurate positioning information.
Problems Solved

Original Abstract Submitted
Aspects presented herein may enable a UE to reduce sensor initialization time for one or more sensors that are to be used for DR positioning during a GNSS signal outage. In one aspect, a UE initiates a first positioning engine based on an availability of a GNSS signal, where the first positioning engine measures a relative position of the UE without ambiguity processing. The UE calibrates at least one IMU sensor based on the relative position of the UE measured by the first positioning engine. The UE performs a positioning calculation of the UE via the at least one IMU sensor in response to the GNSS signal being unavailable.
