-The primary goal for the summer is to provide a working implementation of a GNSS receiver working with SBAS signals: Signal acquisition and tracking algorithms for their specific signals. The outcome should be a robust GNSS receiver capable of delivering RINEX-B files and real-time navigation solutions including SBAS information.

-Implement acquisition and tracking algorithms for EGNOS signals, following the examples already implemented for other GNSS signals. This would facilitate research on precise positioning, safety positioning and and drone-related activities working with real signals. Demodulation of the navigation message, opening the door to open innovation in multi-constellation receivers.

+## Project Title: Vector Tracking
+
+### Description:
 
+Large-sized project (350 h)
+
+This Google Summer of Code initiative aims to enhance vector tracking capabilities between GNSS (Global Navigation Satellite System). The goal is to develop a functional GNSS-SDR receiver capable of performing Vector Tracking. It is well-known that the use of Vector Tracking Loops (VTL) in GNSS receivers can result in improved tracking performance and sensitivity, faster acquisition, and improved interference robustness. This project leads to a real-time SDR GNSS VTL receiver capable of working with different COTS front-ends.  These methods will enhance research on sensor fusion, precise positioning, and urban canyon navigation using real-world signals.
