This paper examines the potential in extracting the instantaneous location of maritime moving targets using a passive multistatic radar with Global Navigation Satellite Systems (GNSS) as illuminators of opportunity and a single receiver. This paper presents a theoretical framework for the localization of a moving target from a set of bistatic range measurements. The algorithm and its predicted accuracy are presented. The localization is achieved by what is essentially a multilateration technique, which can be applied while the transmitting platform is also in motion. The algorithms and the accuracy predictions, as a function of the number of transmitters, have been experimentally confirmed via a dedicated experimental campaign, where two different maritime targets were detected by up to 12 GNSS satellites belonging to different satellite constellations (GPS, GLONASS, and Galileo) simultaneously. To the best of the author’s knowledge, these are the first results of their kind and on this scale not only for GNSS-based passive radar but also for multistatic radar in general.

Satellite-based navigation systems have provided a tremendous enhancement during the last decade. Global Positioning System leads the alternative systems not only in the global case but also in regional ones. Regional positioning systems offer independent, indigenously developed satellite navigation systems operating at various orbits and slots. Because geostationary satellites have limited coverage areas compared with medium earth orbit Global Navigation Satellite System satellites, they offer a lack of complexity and reduced operational costs. In this study, a conceptual regional positioning system design using Turksat geostationary communications satellites is proposed and simulated positioning accuracy merits are presented.
