TDoA-based Localization Using Enhanced Multilateration
For the IPSN 2016 Microsoft indoor localization competition, we propose a system based on uplink TDoA using commerically available hardware from Nanotron and a proprietary multilateration algorithm.
متن کاملLinear system construction of multilateration based on error propagation estimation
Iterative localization algorithms are critical part in the control of mobile autonomous robots because they feed fundamental position information to the robots. In a harsh unknown environment, the estimation of environmental noise is hardly obtained during the movement of the robots. It means that the state-of-the-art methods, which increase localization accuracy using error management, are uns...
متن کاملMultipath-Aided Direct Position Estimation
In contrast to multipath rejection techniques, in Multipath-Aided Direct Position Estimation (MA-DPE), multipath signals are transformed from being unwanted interference to being additional navigation signals coming from virtual satellites at their mirror-image positions after building reflection. These signals are then deeply integrated via Direct Position Estimation (DPE), where the receiver ...
متن کاملThe TDOA system topology optimization from signal source position error estimation point of view
This article is focused on a problem of the error estimation of the radar signal source localization by the TDOA (Time Difference of Arrival) method. More precisely, it is focused on the finding and solving of an analytical equation (error equation) that describes the source position error without any mathematical simplifications and approximations. The solution of this analysis is the covarian...
متن کاملHigh Speed High Accuracy Multilateration System Based on Tracking Interferometers
The use of tracking interferometers has gained industrial application for the testing and the calibration of measuring and production machines. The concept is based on sequential multilateration [1] and can realize calibration uncertainties in the sub-micron order. Another application for tracking interferometers is the real-time multilateration for accurate and highly dynamic measurement of 3D...
