Precise kinematic GPS surveying can provide users with the precise position,velocity,attitude and time information of the moving platform in real-time or post-processing modes. It is now increasingly used for many surveying and navigation applications on land,at sea or in the air. Precise kinematic GPS surveying in single-baseline mode is investigated with the emphasis on the (near) instantaneous ambiguity resolution for short-baselines,on the ambiguitiy resolution for long-baselines and on quali...
