Abstract
Two high-precision positioning techniques currently offer accur acy at the centimetre level: Real-Time Kinematics (RTK) and Precise Point Positioning (PPP). Both methods use carrier-phase measurements, 2 orders of magnitude more prec ise than pseudoranges. Classical single-baseline RTK (appeared in the 80’s) uses a nea rby reference station to compensate most of the delays (i.e., errors) affecting GNSS sig nals. RTK achieves centimetre-level of accuracy in seconds after the Double Differ ences...
