Train Localization Environmental Scenario Identification Using Features Extracted from Historical Daonment is complex and changes with the train movement, buildings, trees, railroad cuts and mountains will block and reflect the GNSS signals, which will bring errors to the GNSS-based train position estimation. This paper proposes a railway scenario identification method based on historical GNSS rec

Research on the Method of Precisely Removing Open Water in the Retrieval of Soil Moisture by Spacebot impact on the results of soil moisture retrieval. In order to solve this problem, this paper proposes a method to accurately remove open water based on the geographic coordinates of the mask data, and verifies it using the measured spaceborne data. Firstly, we obtained CYGNSS level 1 data for a pe

Model Establishment of Atmospheric Weighted Mean Temperature in Chongming Eco-Island and Its Applicaelt. Due to the special geographical location of Chongming, it is affected by typhoons almost every year, which have caused serious damage to the ecological environment and economic development. A typhoon often brings a large amount of water vapor. Thus, studying characteristics of water vaper durin

Analysis of COSMIC-2 Atmospheric Boundary Layer Detection Abilitybeen a difficult point in the field of satellite navigation research. Moreover, atmospheric boundary layer is a key parameter when studying climatology. With the Constellation Observing System for Meteorology, Ionosphere, and Climate (COMSIC)-2 occultation launching in June 2019, it enhances the abi

A New Grid Model for the Vertical Correction of Zenith Hydrostatic Delay for Chinaical direction is much greater than that in the horizontal direction. Some shortages still exist in current zenith hydrostatic delay (ZHD) vertical stratification models for China, such as only single gridded data is used for modeling. To address those of drawbacks, a new approach, the sliding windo
