Special Issue Information
Dear Colleagues,
Global Navigation Satellite Systems (GNSSs) have revolutionized positioning, navigation, and timing (PNT) technologies, serving as a cornerstone for applications ranging from autonomous vehicles and precision agriculture to disaster monitoring and geodetic surveying. The advent of multi-frequency signals from modernized GNSS constellations (e.g., GPS L5, Galileo E5/E6, BDS-3 B1c/B2a/B2b, and GLONASS L3) has unlocked unprecedented opportunities for enhancing the accuracy, reliability, and convergence speed of high-precision positioning. Multi-frequency GNSSs enable advanced signal processing techniques, such as improved ambiguity resolution, better mitigation of ionospheric delays, and enhanced robustness against environmental disturbances. However, challenges persist in fully exploiting these signals, including in the development of efficient multi-frequency RTK/PPP/PPP-RTK models, handling inter-frequency biases, ensuring system integrity, and deriving high-resolution atmospheric products. This Special Issue aims to address these challenges by showcasing cutting-edge research and fostering interdisciplinary collaboration in multi-frequency GNSS technology.
This Special Issue seeks to compile high-quality research and review articles that advance the theory, algorithms, and applications of multi-frequency GNSS in high-precision positioning and navigation. By focusing on innovations in signal processing, error modeling, and system integration, this collection will highlight how multi-frequency GNSS can address emerging demands in both scientific and industrial domains.
Remote sensing emphasizes the use of satellite-based and remote sensing technologies for Earth observation and spatial data analysis. The Special Issue aligns with the journal’s scope by exploring GNSSs as a critical remote sensing tool for atmospheric studies, deformation monitoring, and real-time navigation—all of which rely on advancements in multi-frequency signal utilization.
We invite submissions addressing, but not limited to, the following themes:
- Multi-frequency GNSS Positioning Models:
RTK, PPP, PPP-RTK algorithms leveraging multi-frequency signals;
Inter-system and inter-frequency bias estimation/calibration.
- Ambiguity Resolution and Error Mitigation:
New methods for fast and reliable multi-frequency ambiguity resolution;
Ionospheric/tropospheric delay modeling and real-time correction;
Multi-sensor integration (e.g., INS, LiDAR) for robust navigation.
- GNSS Integrity and Atmospheric Applications:
Integrity monitoring frameworks for safety-critical systems;
GNSS-derived atmospheric products (e.g., ionospheric TEC, tropospheric zenith delays);
Crowdsourced GNSS data for weather forecasting and climate studies.
- Emerging Technologies and Datasets:
Low Earth Orbit (LEO) satellite-augmented GNSS positioning;
Machine learning/AI-driven approaches for multi-frequency signal processing.
Article Types: Original research articles, comprehensive reviews, case studies, and technical notes are welcome. Submissions should demonstrate methodological rigor, novelty, and practical relevance.
