GEOTAGGING PHOTO SMARTPHONE APP USING GALILEO DIFFERENTIATORS
EGNSS4ALL is an Open-Source mobile phone application for iOS and Android. It takes advantage of GNSS raw measurements and EGNSS differentiators (EGNOS, dual frequency capabilities and Open Service – Navigation Message Authentication – OSNMA) for trustworthy and accurate geotagging. Inside the App, the user can perform several different tasks:
•Taking photos, storing the position data (PVT), and representing them on the map;
•Retrieving raw data about a specific point on the map through GNSS Raw Data;
•Having access to GNSS SkyMap, showing the location of the satellites of the four global constellations (GPS, GALILEO, GLONASS, BeiDou) allowing for Two-Line Element (TLE) cross-check
•Assisted-NMA architecture providing authenticated positioning.
EGNSS4ALL unique functionalities improve the performance and trustworthiness of smartphone photo geotagging, mapping and tracking, serving multiple domains including (but not only) urban planning, logistics, and insurance.
