A novel framework for processing raw GNSS measurements on an Android smartphone

This is a repository of the Open Aided Navigation project. The project aims to demonstrate and explain state of the art methods of modern aided inertial and satellite (GNSS) navigation, and multi-sensor localization. The software provided in this repository is written in Matlab.

A novel deep transfer learning framework for forecasting NavIC satellite ephemeris and clock errors. PRESTO overcomes extreme data scarcity using a hybrid architecture (GNNs + Semiparametric Decomposition + Autoformers) and synthetic data augmentation to generate normally distributed prediction residuals.

Official Arduino library for interfacing with the 7Semi L89HA GNSS Module over UART. This library enables easy communication and data parsing of NMEA sentences, allowing you to retrieve GPS location, time, and satellite data with minimal effort.

C++ implementation of EKF_GEOS3, an Extended Kalman Filter for GEOS-3 satellite orbit determination. Features custom matrix algebra, JPL DE430 ephemerides, IERS corrections, and full astrodynamics modeling.

Simple C++ Simulator and ROS 2 Node for GNSS.

Star trackers are ubiquitous spacecraft sensors that typically provide high-accuracy attitude information to the spacecraft’s guidance, navigation, and control (GNC) system.
