Positioning using wave signal measurements is used in several applications, such as GPS systems, structure from sound and Wifi based positioning. Mathematically, such problems require the computation of the positions of receivers and/or transmitters as well as time offsets if the devices are unsynchronized. In this paper, we expand the previous state-of-the-art on positioning formulations by introducing Multiple Offsets Multilateration (MOM), a new mathematical framework to compute the…

Sensor Networks TDOA Self-Calibration: 2D Complexity Analysis and Solutions

This paper considers 2D networks with synchronized receivers but unsynchronized transmitters and the corresponding calibration techniques, known as Time-Difference-Of-Arrival (TDOA) techniques, and presents a novel approach which gives an algebraic solution to two previously unsolved scenarios.

Homotopy Continuation for Sensor Networks Self-Calibration

This paper uses homotopy continuation to solve four previously unsolved configurations in 2D TDOA self-calibration, including a minimal one, and presents new subminimal solvers, which can be used to achieve unique accurate solutions in previously unsolvable configurations.

Stratified sensor network self-calibration from TDOA measurements

A non-iterative algorithm is proposed that applies a three-step stratification process, using a set of rank constraints to determine the unknown time offsets, and applying factorization techniques to determine transmitters and receivers up to unknown affine transformation.

Node localization in unsynchronized time of arrival sensor networks

A method for localizing a set of receivers and directions from transmitters placed far from the receivers, measuring unsynchronized time of arrival data and getting a reconstruction of the receivers with a relative error of 14%.

A complete characterization and solution to the microphone position self-calibration problem

This paper presents a complete characterization and solution to microphone position self-calibration problem for time-of-arrival (TOA) measurements and derive efficient and numerically stable algorithms for the minimal TOA based self-Calibration problems.

TOA sensor network calibration for receiver and transmitter spaces with difference in dimension

Trilateration and iterative multilateration algorithm for localization schemes on Wireless Sensor Network

This research will use localization method RSSI, the distance estimation method using the signal strength in the sensing to all nodes, to estimate the position of the static nodes with the lowest possible position errors in Wireless Sensor Network.

A Self-Localization Method for Wireless Sensor Networks

This work develops necessary conditions for solving the self-calibration problem and provides a maximum likelihood solution and corresponding location error estimate, and compute the Cramér-Rao bound of the sensor node location and orientation estimates, which provides a lower bound on calibration accuracy.

Experimental results are presented demonstrating the proposed stationary receiver estimating its position using Doppler measurements from 2 Orbcomm LEO satellites with an accuracy of 360 m over a 1 minute period.

Revisiting trilateration for robot localization

New formulas for the variance and bias of the unknown robot location estimation, due to station location and range measurements errors, are derived and analyzed and are proved to be more tractable compared with previous ones, because all their terms have geometric meaning, allowing a simple analysis of their asymptotic behavior near singularities.
