beidou

Matlab codes to generate GNSS PRNs, secondary codes, dataless signals and spectra. Includes real data captures and a theory summary. GPS (L1CA, L2C, L5), Gaileo (E1OS, E5), BeiDou-2 (B1I)

FAST is a GNSS Data Download and Processing software developed in Python. The software adopts a modular architecture, consisting of four main components: data download, quality analysis, SPP, and station selection

Python software for multipath analysis of GNSS observations

学习PY，使用PY实现卫星单点定位、rtk相对定位算法

A collection of awesome GNSS/RNSS related sources, tools, data, MOOC's course, etc.

BeiDou B1C Signal Generator and Catcher / 北斗B1C信号生成与捕获

Multi-constellation GNSS SDR signal simulator in Rust — GPS (L1CA/L5/L2C/L1C), Galileo (E1/E5a/E5b/E6), BeiDou (B1C), GLONASS (G1). Generates IQ baseband samples from RINEX 3.04 ephemeris.
