Review of triple-frequency GNSS: ambiguity resolution, benefits and challenges
Triple-frequency GNSS has been intensively studying in the past decades, especially with the open service of China’s BeiDou system. In this review, we will address the ambiguity resolution, benefits gained from additional frequency signals compared to the dual-frequency GNSS signals, as well as analyse the challenges of triple-frequency GNSS for future development. We first review and compare t...
متن کاملPenalized GNSS Ambiguity Resolution
Global Navigation Satellite System (GNSS) carrier phase ambiguity resolution is the process of resolving the carrier phase ambiguities as integers. It is the key to fast and high precision GNSS positioning and it applies to a great variety of GNSS models which are currently in use in navigation, surveying, geodesy and geophysics. A new principle of carrier phase ambiguity resolution is introduc...
متن کاملA New GNSS Single-Epoch Ambiguity Resolution Method Based on Triple-Frequency Signals
Fast and reliable ambiguity resolution (AR) has been a continuing challenge for real-time precise positioning based on dual-frequency Global Navigation Satellite Systems (GNSS) carrier phase observation. New GNSS systems (i.e., GPS modernization, BDS (BeiDou Navigation Satellite System), GLONASS (Global Navigation Satellite System), and Galileo) will provide multiple-frequency signals. The GNSS...
متن کاملThe Key to GNSS Ambiguity Resolution
One of the major obstacles in resolving ambiguities for longer baselines is the presence of unmodeled ionospheric delays. One technique to deal with this problem is to include ionospheric delay parameters in the observation equations, and estimate them as unknown states. The purpose of this article is to analyze this technique in light of the future signals that will be available through GPS mo...
متن کاملGNSS antenna array-aided CORS ambiguity resolution
Array-aided precise point positioning is a measurement concept that uses GNSS data, frommultiple antennas in an array of knowngeometry, to realize improvedGNSS parameter estimation proposed by Teunissen (IEEE Trans Signal Process 60:2870–2881, 2012). In this contribution, the benefits of array-aided CORS ambiguity resolution are explored. The mathematical model is formulated to show how the pla...
