Demonstration of cold snapshot GNSS
Author: Jonas Beuchert
This script shows how to obtain a GNSS position fix from an 11-millisecond raw GNSS signal snapshot without any prior knowledge about the position of the receiver and only coarse knowledge about the time.
Algorithm adapted from:
Ignacio Fernández-Hernández and Kai Borre. “Snapshot positioning without initial
information”. In: GPS Solutions 20.4 (Mar. 2016), pp. 605–616
Setup
Clone snapshot-gnss-algorithms to your machine.
Follow the setup instructions for snapshot-gnss-algorithms.
Add the files from this repository to the cloned directory.
Download some exemplary data to the cloned directory.
Run demo_cold_snapshot.py with Python 3, e.g., open a terminal and execute python3 demo_cold_snapshot.py in the cloned directory.
