Abstract
This paper presents results of research concerning determination of the GPS reference station coordinates located on the grounds of an EPDE airport in Deblin. The study uses a mathematical model of the PPP measurement technique in order to determine the coordinates of the reference station using the real GPS code-phase observations. The computations of the coordinates of the GPS reference station were carried out in numerical applications CSRS-PPP, APPS and GAPS. In this research was found that the accuracy of finding solutions to the XYZ geocentric coordinates of the reference station REF1 between solutions CSRS-PPP, APPS and GAPS ranges from 0.01m to 0.13m. In addition, the accuracy of determining the XYZ geocentric coordinates from the PPP method related to the GPS differential solution ranged from 0.01m to 0.11m.
Highlights
One of the elements of activating the GBAS augmentation system in air transport is the construction of a network of the RTK GPS permanent stations, located in the vicinity of both civil and military airports [1]
The GBAS augmentation system should consist of three components: the base station RTK GPS located at the airport, the mobile GPS receiver installed on board of an aircraft and transmission links of satellite data between the base station and the mobile receiver [2]
In the DGPS differential technique, the position of an aircraft is determined based on the GPS code observations, registered by the base station and the mobile receiver
Summary
One of the elements of activating the GBAS augmentation system in air transport is the construction of a network of the RTK GPS permanent stations, located in the vicinity of both civil and military airports [1]. The precise coordinates of the RTK GPS reference station were determined using the PPP universal measurement technique for the GPS code-phase observations. There was the PPP precise measurement technique was used in order to determine coordinates of the reference station REF1 in the XYZ geocentric frame.
