Comparative Performance of Real-Time GNSS Positioning Solutions for Marine Applications Under Different Correction Strategies
Accurate and reliable positioning is a fundamental requirement for marine applications, particularly in hydrographic surveying, where real-time data acquisition is essential. Despite recent advances in Global Navigation Satellite System (GNSS) technologies, the comparative performance of different real-time correction...

A high-precision shipborne strapdown gravimetry method adaptively robust to global navigation satellite system signal anomalies
The signal anomalies of global navigation satellite system (GNSS) are the key factors for the performance of shipborne strapdown gravimetry. In order to obtain reliable gravity information in real-time and at low operating cost in the conditions of signal outages or interference, we show a high-precision strapdown gr...

A novel real-time PPP-AR framework for continuous crustal deformation monitoring across Japan
Kinematic precise point positioning (PPP) is a powerful technique for Global Navigation Satellite System (GNSS)-based real-time crustal deformation monitoring. However, PPP float solutions are often affected by sub-daily periodic fluctuations, caused by orbit errors and atmospheric delays, thereby motivating the adopti...

Lunar Surface Receiver Clock Synchronization Using GNSS and Satellite Nadir Angle
The use of signals from Earth-orbiting Global Navigation Satellite System (GNSS) constellations for positioning, navigation, and timing on the lunar surface was recently demonstrated by the Lunar GNSS Receiver Experiment (LuGRE) aboard Blue Ghost Mission 1. For receiver clock synchronization using GNSS, Kalman filter p...

A new ISL-aided method for improving real-time kinematic orbit and clock estimation robustness of LEO satellites with degraded onboard observations
Onboard global navigation satellite system (GNSS) receivers have become the most convenient means to realize autonomous orbit determination and clock estimation for low Earth orbit (LEO) satellites. However, signal outages and blockages in complex space environments cause GNSS observation degradation, which restricts t...
