For short data sets, positions will effectively be calculated using only the pseudo-range observations. Longer data sets make it possible

Maximum duration of GPS data set Data sets up to six days long can be processed with PPP providing the uncompressed RINEX observation file is less than 100Mb. Submission of a file exceeding 1

21、 of the antenna phase centre realised by the processed observations. In order to obtain the position of the ground marker, the vertical distance between the ground marker and the antenna reference point (ARP) as well as the distance between the ARP and the antenna phase centre (APC) must be known.,A

22、RP to Marker,The vertical distance between the point to be positioned and the antenna reference point is a function of the antenna installation. If known , the ARP to marker distance in units of metre should be input as the H component of the ANTENNA: DELTA H/E/N RINEX header record. Note that the E

23、 and N components, even if non-zero, are not considered in the PPP computations at this time.,ARP to ACP,The distance between the antenna reference point and its phase center is frequency dependent and a function of the electronic characteristics of the antenna. It is usually obtained from laborator

Online PPP uses the antenna phase centre calibration values published by the International GPS Service (IGS) and by the U.S. National Geodetic Survey (NGS).
