TL;DR: In this article, a GNSS satellite clock error real-time estimation quality control method aimed at characteristics that real time clock error estimation has high requirement on observation data quality and cannot perform post residual error edition.

TL;DR: In this article, the authors proposed a real-time satellite real time orbit determination method based on a satellite-borne GNSS, which comprises preprocessing data, setting an initial value, calculating the satellite position and velocity predicted at the next moment, a state transition matrix and the state noise covariance matrix of a state equation, and setting a counting unit.

TL;DR: In this article, a real-time satellite clock error estimation system and method based on a GNSS high precision system was proposed, where data is received by a data reception and reading subsystem and is read in real time, and the data is stored and transmitted to a real time data pre-processing subsystem; the received data is pre-processed by the realtime data preprocessing subsystem to generate observation data after quality inspection.

TL;DR: In this article, a monitoring system for settlement of a high-speed railway is presented, where the system comprises an acquisition system and a cloud platform, wherein the acquisition system comprises a base station and a monitoring station positioned at a monitoring point, wherein both the monitoring station and the base station both receive satellite signals and process the satellite signals to obtain observation data; the cloud platform comprises a data processing system, a data storage system and monitoring early warning system; the data processing systems is used for storing the current position, and the monitoring early-warning systemis used for comparing the current
