In this work, we argue that current state-of-theart methods of aircraft localization such as multilateration are insufficient, in particular for modern crowdsourced air traffic networks with random, unplanned deployment geometry. We propose an alternative, a grid-based localization approach using the k-Nearest Neighbor (k-NN) algorithm, to deal with the identified shortcomings. Our proposal doe...

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...

In this paper, we present a novel geometrically driven multilateration technique that is based on Ultra-Wideband (UWB) technology. We refer to our proposed solution as Time Reflection of Arrival (TROA). We demonstrate in this paper that the position estimation error is improved upon by carefully considering the inherent properties of the UWB technology and the reflection properties of transmitt...

Multilateration (MLAT) is the de facto technique to localize points of interest (POIs) in navigation and surveillance systems. Despite sensors being inherently noisy, most existing techniques i) are oblivious noise patterns sensor measurements; ii) only provide point estimates POI. This often r...

A multilateration algorithm is presented in this work in order to realize a precise localization of the sensor nodes in wireless sensor networks in logistic applications. RSSI (Received Signal Strength Indicator) is used for distance measurements between sensor nodes. The developed algorithm is simulated and afterwards implemented in a real sensor network for food transportation logistic. The t...

The FAA is conducting evaluations of Precision Runway Monitoring (PRM) surveillance techniques. This paper describes the evaluation results of the Multilateration/ADS-B system trials conducted at Atlanta-Hartsfield International Airport (ATL) in 1997. The performance of Time Difference of Arrival (TDOA) position multilateration of aircraft Mode S and Mode A/C transmissions was evaluated, in add...

Traditional multilateration is extended in this work to account for uncertainty in the location of ranging nodes, and used to localize an ad hoc network of mobile SDRs. The technique is first described and then demonstrated in a simulation study. Simulation results show that network localization time is reduced substantially using this technique over conventional multilateration.

In wireless sensor networks, a critical system service is the localization service that determines the locations of geographically distributed sensor nodes. The raw data used by this service are the distance measurements between neighboring nodes and the position knowledge of anchor nodes. However, these raw data may contain outliers that strongly deviates from their true values, which include ...
