Current DGPS Techniques and Flight Applications

Abstract: This paper provides a summarisation of current DGPS techniques in flight applications. Differential GPS (DGPS) was meant for the needs of positioning and distance-measuring applications which is essential for higher accuracies which stand-alone Precise Positioning Service (PPS) or Standard Positioning Service (SPS) GPS could not deliver. This paper elaborates the characteristics of various DGPS systems and comparison of their strengths and weaknesses in flight applications.

Keywords: Differential GPS (DGPS), flight applications
