Leica System 1200 - High Performance GNSS Technology for RTK Applications

Frank Takac, Justin Walford

Open publisher page 10 citations

Abstract

Leica’s newly developed SmartTrack+ technology is designed to track all of the available GNSS positioning signals. SmartTrack+ is now available in the System 1200 range of high performance GNSS sensors. Integrating GNSS technologies effectively increases satellite availability, redundancy and geometry. This paper discusses how these three elements can influence the productivity, reliability, precision and accuracy of RTK positioning. An analysis of real-time data collected using System 1200 sensors illustrates the advantages of a combined GPS and GLONASS constellation in terms of positioning continuity, the time-to-fix ambiguities, the reliability of the ambiguity solution and the precision of the fixed position.
