The Positioning and Tracking Approaches and Technologies 27 Australian Locata system is an example of such a system. 4 GHz ISM band, two frequencies are transmitted by ground-based transmitters that are time synchronized. , 2012). 2 Positioning Methods Based on Cellular Networks The majority of alternative positioning technologies used in LBS operate on the principle of radiolocation, in which the position of an object is determined from processing known characteristics of received radio waves.
Jensen, R. McMaster, and C. ), Chapter 10, Taylor & Francis, New York. 3 should be understood as the best achievable accuracy. 8 GPS Instrumentation Over the past two decades, civilian as well as military GPS instrumentation has evolved through several stages of design and implementation focused primarily on achieving an enhanced reliability of positioning and timing, modularization, and miniaturization. By far, the majority of the receivers manufactured today are of the C/A-code single-frequency type.
The methods most commonly used to mitigate these problems are the proper transmitter and receiver design and the appropriate signal structure. For example, one possible method for eliminating the near-far problem is the technique of pulsing the pseudolite’s signal, while a higher chipping rate (CR) can mitigate the undesired effect of multipath (Progri and Michalson, 2001). In addition, to mitigating multipath errors, helical antennas are usually employed for the transmission of the pseudolite signals.
