2009 IEEE/SP 15th Workshop on Statistical Signal Processing, 2009
In this paper, we develop a new scheme for RTK positioning using multi-constellation GNSS measurements in presence of multipath and ionospheric delays. The proposed procedure for multi-frequency ambiguity resolution is based on four steps: 1) at each epoch, a Gaussian sum particle filter is used to track the user position and the float ambiguity ...

2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010
In this paper, we introduce a new approach for RTK positioning using triple-frequency combinations of GNSS measurements in presence of carrier phase multipath. The proposed method is based on a modification of the LAMBDA method, where the a-priori information on multipath errors is exploited as a constraint in the optimization and ambiguities search ...

Ionospheric Effects on GPS Signals in Real Time Kinematic (RTK) Applications
2006 IEEE/ION Position, Location, And Navigation Symposium, 2006The need for satellite navigation technology, with its capability to provide real time positioning using Global Navigation Satellite System (GNSS) has increased tremendously over the years. However, the positioning accuracy tends to degrade as the baseline increases.

Enhancing Real-Time Kinematic Relative Positioning for Unmanned Aerial Vehicles [PDF]
MachinesReal-time kinematic (RTK) positioning of the global navigation satellite systems (GNSS) is used to provide centimeter-level positioning accuracy. There are several ways to implement RTK but a Kalman filter-based RTK is preferred because of its superior ...

An automatic, centimetre-level accuracy mapping system was developed and evaluated for precision real-time geospatial mapping of transplanted tomato plants. The system utilised a single Real-time Kinematic-Global Positioning System (RTK-GPS) system mounted on the tractor for Global Positioning System (GPS) location mapping of planting events occurring ...

ABSTRACT Firstly, GPS was used for military purpose, now is used to surveying concepts. Today GPS is used to surveying and observations on surveying engineer. Until firstly GPS is one of the new useful methods RTK GPS is enlarged the GPS techniques, for example surveying detail points and stake - out points.

Os métodos de levantamentos topográficos evoluíram tecnologicamente, transpondo-se de equipamentos mecânicos a digitais. O presente trabalho tem como objetivo realizar um estudo comparativo de levantamento topográfico planialtimétrico aplicando a tecnologia VANT (Veículo Aéreo Não Tripulado) com o método de Posicionamento Cinemático em Tempo (RTK).
