A hybrid method of estimating position of a mobile device which utilizes both received signal power and timing measurements. Received signal power of signals received by the mobile device from a plurality of cells are measured and corresponding received signal power measurements are stored. The method further includes measuring, at the mobile device, times of arrival of signals received from the plurality of cells. A plurality of time difference of arrival (TDOA) measurements are determined from the times of arrival. A power-time hybrid Gaussian maximum likelihood estimator and positioning assistance data for the plurality of cells are used to generate a maximum likelihood estimate of the position of the mobile device by evaluating a joint conditional probability of the received signal power measurements and the plurality of TDOA measurements. Gaussian random variables may be used to represent the received signal power measurements and the TDOA measurements.

A system and method for obtaining location data for a portable device relative to an object. The system and method may include an object device disposed in a fixed position relative to the object, the object device having an antenna configured to communicate wirelessly via UWB with the portable device via a communication link.

Disclosed are techniques for wireless communication. In an aspect, a first UE and a second UE perform a ranging procedure which includes communication of one or more ranging signals between the first UE and the second UE. The first UE obtains sensor data via a set of sensors coupled to the first UE, and transmits the sensor data to the second UE in association with the ranging procedure. The second UE determines a distance between the first UE and the second UE based on ranging measurement data associated with the one or more ranging signals and the sensor data.

The present disclosure generally pertains to systems and methods for autonomously detecting and correcting anomalies in position information provided to aircraft using radio-frequency signals. By enabling autonomously detecting and correcting for anomalies in the operation of a ground-based solution entirely independent of GPS, systems of the present disclosure can make the provided position information more accurate and robust, thereby enhancing the effectiveness and safety of navigation systems using the provided position information. More precisely, systems of the present disclosure may employ a series of ground-based beacon transmitters to provide radio-frequency (RF) signal pulse with a highly regular frequency. A locating receiver can detect the arrival times of these pulses and use this information to detect and report certain anomalies. These reports may then be used to autonomously correct the detected anomalies.
