Технология точного точечного позиционирования (метод PPP, от англ.: Precise Point Positioning) представляет собой высокоточный метод позиционирования глобальных навигационных спутниковых систем, дает возможность определить местоположение сантиметровой точности с использованием только одного приемника и точной информации об орбите и времени. В отличие от методов дифференциального позиционирования метод PPP не зависит от наземных опорных станций, что обеспечивает большее глобальное покрытие и значительно повышает эксплуатационную эффективность. Благодаря усовершенствованию четырех глобальных навигационных спутниковых систем – GPS, ГЛОНАСС, GALILEO и BeiDou (BDS) – были значительно улучшены все структуры передачи сигналов, система оповещения о местоположении групп спутников и, следовательно, расширены возможности, достигнутые модернизацией этих систем. Целью проведенного исследования являлось изучение эффективности метода PPP для четырех указанных глобальных навигационных спутниковых систем на примере сравнения времени, необходимого для достижения заданной точности, оценки точности позиционирования и оценки спутников, используемых для получения решения о позиционировании. Результаты исследования расширят знания о мультисистемных приложениях глобальных навигационных спутниковых систем и послужат основой для инновационного развития технологий высокоточной навигации и позиционирования данных систем в таких областях, как геодезия, картография и автономное вождение.

Precise Point Positioning technology is a high-accuracy positioning method of global navigation satellite systems that can achieve centimeter-level positioning accuracy using one receiver and precise orbit and time information. Unlike differential positioning methods, which rely on ground reference stations, Precise Point Positioning provides greater global coverage and significantly higher operational efficiency. The advancement of four global navigation satellite systems – GPS (Global Positioning System), GLONASS (Global Navigation Satellite System), GALILEO (global navigation satellite system), BDS (BeiDou navigation satellite system) – resulted in significant improvements in all signal transmission structures and satellite constellation positioning notifications that expanded the capabilities achieved by the modernization of these systems. The purpose of the study is to investigate the Precise Point Positioning technology performance performance for the four specified global navigation satellite systems by comparing the time they took to converge within a user-defined accuracy, analysis of positioning accuracy, and evaluation of the satellites used to derive the positioning solution. The results of the study will expand knowledge about multi-system applications of global navigation satellite systems and serve as a basis for innovative development of high-precision navigation and positioning technologies for global navigation satellite systems in the fields of surveying, mapping, and autonomous driving.
