“…In Figure 6 we verified the determined XYZ coordinates of the aircraft in the GAPS programme. For this purpose, we determined the difference in the XYZ coordinates of the aircraft between the solution made in the GAPS programme and in the CSRS-PPP programme [13]. The average value of the difference in the X-coordinate is equal to 0.…”

Abstract. The GNSS satellite technique is applied for a designation of the true position of the aircraft vehicle in air transport. In case of air transport, the GNSS satellite technique is implemented within the ABAS, SBAS and GBAS augmentation systems. The aim of this paper is to present and describe the results of applying the GNSS satellite technique in the ABAS augmentation system in air transport. The research experiment was conducted on 1st June 2010 (01.06.2010) at late morning hours on the airfield in the town of Dęblin in the Lubelskie Voivodeship, in south-eastern Poland. Within the research experiment, nearby Dęblin airfield a flight test was executed using a Cessna 172 plane. During the flight test, the dual frequency Topcon HiperPro receiver was installed in the pilot's cabin of the Cessna 172 aircraft. The Topcon HiperPro receiver collected a GPS code, phase and Doppler measurements in order to recover the true position of the aircraft. In this paper the authors present the results of positioning the Cessna 172 during the phase of landing based on the solution of the GPS satellite technique. The position of the aircraft was estimated by means of the Precise Point Positioning (PPP) method in GAPS software for un-difference GPS code and phase observations. The PPP method is applied in air navigation as a precise technique for recovery of position of aircrafts. Especially, designation of true position of the aircraft is very important at the phase of landing on the aerodrome. In this paper, the obtained accuracy for XYZ geocentric coordinates of the aircraft is better than 6 cm at the phase of landing. The precision of the aircraft coordinates from GAPS software was compared with the values from magicPPP and CSRS-PPP softwares. The dispersion of the difference of the aircraft coordinates between GAPS and CSRS-PPP softwares is between -0.5 m and +1.2 m. In addition, the dispersion of the difference of the aircraft coordinates between GAPS and magicPPP softwares is between -0.9 m and +1.8 m.

“…The PPP measurement technique uses the mathematical model of the linear combination equation -"Ionosphere-Free". The computations of the reference position of the aircraft Cessna 172 for the PPP measurement technique were made in the CSRS-PPP programme [12]. In the framework of the calculations performed in the CSRS-PPP programme, the authors used dual frequency P1/P2 code and L1/L2 phase observations from the airborne receiver Topcon HiperPro.…”

This study publishes results of tests with regard to determination of the aircraft positioning accuracy by means of the GPS navigation in aviation. The research exploits the mathematical model of the linear combination "IonosphereFree" in order to designate the coordinates of an aircraft. The research uses the actual GPS code observations, recorded by a satellite receiver mounted in the Cessna 172, at the time of the experiment for the EPDE military aerodrome in Dęblin. The computations of the position of the Cessna 172 aircraft for the linear combination "Ionosphere-Free" were made in the APS Toolbox v.1.0.0. programme. Within evaluation of accuracy of the GPS positioning in aviation, the determined coordinates of the aircraft Cessna 172 from the APS programme were compared to an accurate reference position from the solution derived by the PPP measurement technique. In the research, the authors obtained an average positioning accuracy of approximately 5 m in the geocentric XYZ coordinates and approximately 4 m in the ellipsoidal BLh coordinates. In addition, the 3D-error parameter is lower than 7 m for the XYZ geocentric coordinates.

Horizontal control networks established with monuments are functional if the conditions related to the number of control points, their density, condition and stability of coordinates are met. For functionality defined in those terms, deterministic accuracy characteristics are of little use. The subject matter discussed herein includes the two key features of geodetic control points, i.e., usability and stability. Due to the varying properties of those variables and the impact of the operating time of the system, there is no alternative to reliability-based approach in developing the functionality model. The measures of functionality and the procedures of data acquisition for developing the model of the control network destruction process have been defined. The solution presented herein is relevant for geodetic practice, providing a standard procedure for defining the time frame and the scope of the control network upgrading. The identified destruction process model optimizes this task assuming critical states expressed by the functionality probability. The applied approach is an example of the reliability theory-based approach typical for engineering. The issue of simulating the destruction process is illustrated with the results of the tests of class 3 control networks conducted in Kielce and Lodz regions in Poland. As a result of the tests, the characteristic properties of the control network destruction process have been identified. It was also shown how the patterns of usability and accuracy of the geodetic control points are relevant on the stage of implementing investment project tasks.
