Улучшение характеристик навигационной аппаратуры с использованием будущих перспективных сигналов ГНСС

Abstract

Current state of GNSS, such as GPS, GLONASS, GALILEO (European system), COMPASS (Chinese system) and prospects in the development of various positioning applications designed for these systems are analyzed. Design of multisystem nagivation receivers are analyzed. Capabilities of new signals of global navigation satellite systems and effects on designing navigation devices and accuracy parameters of positioning are considred as well. Different methods of precision positioning and tracking algorithms in different conditions is presented. Results of using different signals received from GNSS systems along with attainable positioning accuracies for various navigation modes are given. Topcon’s new generation of navigation receivers designed with the help of ASIC Vanguard” with 226 universal navigation channels are presented. Characteristics and different operational modes of this precise positioning equipment are described. The characteristics of navigation signals and multipath errors are analyzed. The wide band navigation signals with minimal multipath error are presented.

Анализируется текущее состояние спутниковых навигационных систем GPS, ГЛОНАСС, GALILEO (европейская система), COMPASS (китайская система) и перспективы их развития для различных приложений позиционирования. Рассматривается особенности построения навигационной мультисистемной аппаратуры. Анализируются возможности использования новых сигналов глобальных навигационных спутниковых систем и их влияние на построения навигационной аппаратуры и точностные характеристики позиционирования. Рассматриваются различные методы высокоточного позиционирования и методы слежения за сигналами в сложных условиях. Приводятся достигаемые точности позиционирования в различных режимах навигационной аппаратуры. Рассматриваются свойства навигациооных сигналов и их влияние на ошибку многолучевости. Приводятся примеры широкополосных сигналов, которые позволяют существенно уменьшить ошибку многолучевости.
