How to enable raw GNSS data in u-blox NEO-M8N (Firmware 2.01)

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.

This code implements a firmware for extracting data from an SBG Ellipse-2N sensor. It configures three serial interfaces to communicate with the sensor and other devices, and reads data from the sensor to extract Euler angles, navigation data, and GPS data.

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.
