 GPS sensors locate themselves through a process called

+\emph{trilateration}~\cite{bib:gps-book}. This process consists of
 measuring the distance from 4 or more points in space (satellites),
 whose positions are known. Given the distance measurements, the GPS
 sensor then performs a least square estimation to determine its
