The Position Estimation (PE) accuracy of an MLAT system depends on several factors, one of which is the choice of reference station used to generate the TDOA estimations for use with the lateration algorithm. Furthermore, the closed-form lateration algorithm is known to introduce bias in the PE process. Thus, a bias analysis and improvement in the PE accuracy of an MLAT system with a reference selection technique is presented in the paper. The analysis is carried out for a square GRS configuration with each GRS equipped with a receiver whose Time of Reception (TOR) error Standard Deviation (SD) is assumed 1 nsec. Monte Carlo simulation result of lateration algorithm with reference selection technique shows a reduction of at least 75 in both the overall PE Mean Square Error (MSE) and bias. Furthermore, the PE Root Mean Square Error (RMSE) obtained by the lateration algorithm is reduced by at least 50 out of which 36 of the reduced PE RMSE is contributed only by the TOR estimation error. © 2018 ADVANCES IN ELECTRICAL AND ELECTRONIC ENGINEERING. date: 2018 publisher: VSB-Technical University of Ostrava official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85054060411&doi=10.15598%2faeee.v16i3.2776&partnerID=40&md5=a64fe2bc3238a1c350d886841aeeaa2f id_number: 10.15598/aeee.v16i3.2776 full_text_status: none publication: Advances in Electrical and Electronic Engineering volume: 16 number: 3 pagerange: 332-340 refereed: TRUE issn: 13361376 citation: Yaro, A.S. and Sha�Ameri, A.Z. and Kamel, N.
