Software defined radio based receiver for TDOA positioning system

The paper is aimed at the determination and verification of system parameters, that can be achieved with the utilization of commonly available RTL-SDR software defined receiver in TDOA based system intended for position determination of the small-UAS. The paper describes a way of performing practical experiments, measurement setup and properties of the signal used. Experimental results lead to the specification of potentially achievable accuracy and resolution of time difference of arrival measurement.
