Using Carrier-Phase Measurements of GPS Signals and RTK in Enhanced Positioning

Original language description

GPS or, generally, GNSS based navigation is nowadays a common way to determine position, velocity, and time. The accuracy of such quantities strongly depends on a receiver and connected antenna. This paper deals with just a customer-grade receivers and antennae, namely with a uBlox NEO-6P and a Taoglas A.40.A.301111. This kind of receiver provides a 50 channel tracking capability on the GPS L1 frequency with C/A code and SBAS corrections. The accuracy of such a receiver is about 2.5 m (CEP) without corrections and with SBAS corrections it reaches about 2.0 m (CEP). Nevertheless, when a precise mode is switched on with SBAS corrections the accuracy can go down to less than 1.0 m (CEP). The contribution of this paper lies then in studying the accuracy of the positioning capability with such a receiver and antenna under different modes of operation. Enhanced performance is further reached by u usage of RTK (Real-Time Kinematic) capability of GPS which can provide cm-level accuracy even with a customer-grade means. RTK-GPS positioning relies on carrier-phase measurements of GPS signals and as such the receiver ought to provide raw binary data messages. RTK-GPS has been originally used in applications like geodetic survey; however, applications have recently expanded widely for instance to mobile mapping system, precise vehicles navigation, construction machine control, and precision agriculture. The study of the positioning accuracy is in the paper supported by in-field experiments.
