Improving the Performance of Multi-GNSS (Global Navigation Satellite System) Ambiguity Fixing for Airborne Kinematic Positioning over Antarctica [PDF]
, 2019 Conventional relative kinematic positioning is difficult to be applied in the polar region of Earth since there is a very sparse distribution of reference stations, while precise point positioning (PPP), using data of a stand-alone receiver, is ...

MULTI-GNSS PPP: An Alternative Positioning Technique for Establishing Ground Control Points
International Journal of Environment and Geoinformatics, 2020 Traditionally, ground control points (GCPs) are utilized to determine absolute image orientations indirectly in aerial triangulation. For a long time, differential and relative GNSS (Global Navigation Satellite System) positioning techniques have been ...

Reliable Multi-GNSS Real-Time Kinematic Positioning [PDF]
2018 International Symposium ELMAR, 2018 Surveying, agriculture and the navigation of autonomous robots, cars, ships and aerial systems require Global Navigation Satellite Systems (GNSS) for precise positioning. In this paper, we describe a Real-Time Kinematic (RTK) positioning method, that uses both GPS and Galileo measurements with a common reference satellite, estimates a pseudorange ...

Land Degradation &Development, EarlyView.ABSTRACT Soil disturbance resulting from forest harvesting activities can have significant and lasting environmental consequences, particularly in sensitive ecosystems such as Mediterranean forests. Skid trails, the routes used by machinery to extract timber, are among the most critical areas of impact, and their detection is critical for assessing ...
