Abstract

GPS is undoubtedly the most popular and widely used three-dimensional positioning technology today, but despite this, cannot provide the positioning requirements in many everyday environments, such as urban and indoors. Locata’s solution to these “challenging” environments is to deploy a network of terrestrially-based transceivers that transmit ranging signals. For any terrestrially-based radio frequency (RF) systems, typically the signal from the transmitter arrives at the receiver antenna at a very low (less than 10 degree) or negative elevation angle, and as a result suffer from severe multipath in the form of signal fading. In this paper Locata’s “signal diversity principle” solution to this “real-world” problem is presented. It is shown that in a moderate signal fading environment a system of dual transmit LocataLites, employing spatial diversity principles, can provide cm-level accurate RTK position solutions 100% of the time.
