The purpose of this paper is to present the problem of implementation of the differential global navigation satellite system (DGNSS) differential technique for aircraft accuracy positioning. The paper particularly focuses on identification and an analysis of the accuracy of aircraft positioning for the DGNSS measuring technique.,The investigation uses the DGNSS method of positioning, which is based on using the model of single code differences for global navigation satellite system (GNSS) observations. In the research experiment, the authors used single-frequency code observations in the global positioning system (GPS)/global navigation satellite system (GLONASS) system from the on-board receiver Topcon HiperPro and the reference station REF1 (reference station for the airport military EPDE in Deblin in south-eastern Poland). The geodetic Topcon HiperPro receiver was installed in Cessna 172 plane in the aviation test. The paper presents the new methodology in the DGNSS solution in air navigation. The aircraft position was estimated using a “weighted mean” scheme for differential global positioning system and differential global navigation satellite system solution, respectively. The final resultant position of aircraft was compared with precise real-time kinematic – on the fly solution.,In the investigations it was specified that the average accuracy of positioning the aircraft Cessna 172 in the geocentric coordinates XYZ equals approximately: +0.03 ÷ +0.33 m along the x-axis, −0.02 ÷ +0.14 m along the y-axis and approximately +0.02 ÷ −0.15 m along the z-axis. Moreover, the root mean square errors determining the measure of the accuracy of positioning of the Cessna 172 for the DGNSS differential technique in the geocentric coordinates XYZ, are below 1.2 m.,In research, the data from GNSS onboard receiver and also GNSS reference receiver are needed. In addition, the pseudo-range corrections from the base stations were applied in the observation model of the DGNSS solution.,The presented research method can be used in a ground based augmentation system (GBAS) augmentation system, whereas the GBAS system is still not applied in Polish aviation.,The paper is destined for people who work in the area of aviation and air transport.,The study presents the DGNSS differential technique as a precise method for recovery of aircraft position in civil aviation and this method can be also used in the positioning of aircraft based on GPS and GLONASS code observations.

使用 DGNSS 技术对 GPS 和 GLONASS 数据进行飞机定位

本文的目的是提出差分全球导航卫星系统 (DGNSS) 差分技术在飞机精确定位中的实施问题。论文特别着重于DGNSS测量技术对飞机定位精度的识别和分析。,本研究采用基于全球导航卫星系统(GNSS)单码差模型的DGNSS定位方法。观察。在研究实验中，作者在全球定位系统（GPS）/全球导航卫星系统（GLONASS）系统中使用了来自机载接收机Topcon HiperPro和参考站REF1（机场军用参考站）的单频码观测。位于波兰东南部德布林的 EPDE）。在航空测试中，大地测量 Topcon HiperPro 接收器安装在 Cessna 172 飞机上。本文介绍了空中导航 DGNSS 解决方案中的新方法。分别使用差分全球定位系统和差分全球导航卫星系统解决方案的“加权平均”方案估计飞机位置。飞机的最终结果位置与精确实时运动学 - 飞行解决方案进行了比较。在调查中，指定了在地心坐标 XYZ 中定位飞机 Cessna 172 的平均精度大约等于：+0.03 ÷ +0.33沿 x 轴为 m，沿 y 轴为 -0.02 ÷ +0.14 m，沿 z 轴约为 +0.02 ÷ -0.15 m。而且，DGNSS 差分技术在地心坐标 XYZ 中确定 Cessna 172 定位精度的均方根误差低于 1.2 m。在研究中，需要来自 GNSS 机载接收机和 GNSS 参考接收机的数据. 此外，在 DGNSS 解决方案的观测模型中应用了来自基站的伪距校正。所提出的研究方法可用于地基增强系统 (GBAS) 增强系统，而 GBAS 系统仍然不能适用于波兰航空。,该论文适用于在航空和航空运输领域工作的人员。,
