Data processing, analysis and estimation utilities for a GNSS receiver array

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)

VHDL codes to generate GPS L1 C/A and Galileo E1OS and E5 PRNs and dataless signals. Secondary codes not included.

Decoder for GNSS Navigation messages

precise point positioning (PPP) with GNSS systems precise point positioning with GNSS satellites based on ESA books. It is good for those who study Geomatics/Geodesy and are interested in PPP and satellite Geodesy

This repository contains MATLAB scripts and code snippets for analyzing and resolving ambiguities in positioning systems, with a focus on integrity analysis. The scripts provide implementations of algorithms and techniques for resolving ambiguities in positioning data, computing integrity metrics, and visualizing the results.

This exercise focuses on processing Global Navigation Satellite Systems (GNSS) data, particularly emphasizing double differences (DD) and cycle slip detection. The dataset provided represents a static GPS measurement campaign conducted in a densely populated urban environment, comprising five stations labeled HH01 to HH05.

Positioning and Location Based Services assignments

This is a slant delay forward model based on ray tracing for determination of the GNSS signal path through the NWP model grid.
