After a brief introduction to the primary and secondary radar (radio detection and ranging) systems, emphasizing multilateration technique (along with the possible errors due to non-ideal physical components), I describe the multilateration radar system, developed in laboratory 619, consisting the Squitter (beacon), and the base station (receiver and data processing unit).

Main subjects are construction plans, data formats, hardware and software descriptions, and measurements (verifying the usability of the separate components and the whole system) of both the Squitter and the base station.

I include suggestions to improve the Squitter performance by adding speed-related information to the output data.

The construction of a GPS module testing device is introduced, used for selecting the most sensitive receiver module available, describing the output data formats, used by the most common GPS receiver-modules.

In the end I summarize my results and I mention some of the possible practical future uses of the system.
