Estimation of position from multistatic Doppler measurements

2010 13th International Conference on Information Fusion, 2010
We implement and evaluate a method infer position from Doppler measurements in a multistatic sonar scenario and present a likelihood approach for doing so. Doppler measurements are used to create likelihood surfaces for each of the transmitter-receiver pairs.

Positive power Doppler signal in plantar fasciitis

Rheumatology International, 2011
The plantar fascia is a multilayered band of fibrous tissue that support and maintain the longitudinal arch of the foot. We report a 34-old obese woman with heel pain for the past 3 years. On physical examination, she presented painful plantar fascia throughout extension of the foot.

Receiver Design for Doppler Positioning with Leo Satellites

ICASSP 2019 - 2019 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2019
A framework for positioning with low Earth orbit (LEO) satellite signals is proposed. The framework employs an extend Kalman filter (EKF) to estimate a receiver’s position using Doppler frequency measurements from LEO satellites. The satellites’ positions and velocities are known through two-line element (TLE) files.

Doppler-aided position estimation for HS-GNSS

2019 53rd Asilomar Conference on Signals, Systems, and Computers, 2019
During the last decade, because of the growing needs for indoor navigation, many authors tends to improve the processing gain of the GNSS receivers by increasing the observation time. In this paper, we show that this gain can also be improved by considering the Doppler information during the trilateration step.

Dilution of position in the Doppler-range satellite positioning algorithm

WCC 2000 - ICCT 2000. 2000 International Conference on Communication Technology Proceedings (Cat. No.00EX420), 2002
Depending on different types of users, several algorithms, one of which combines Doppler and range measurements for positioning computation and which is called the D-R algorithm, can be used in software design in a satellite positioning system. The D-R algorithm can be selected for a stationary user in certain circumstance where only few satellites can
