Mobile 3D Mapping Systems
Introduction
GAMMS (acronym for Galileo/GNSS-based Autonomous Mobile Mapping System, in Spanish: Sistema Autónomo de Mapping Móvil Based on Galileo/GNSS) is an ongoing European research and innovation project, funded by the European Union within the Horizon 2020 program. Its main objective is to develop a ground-based autonomous mobile mapping system (AMMS) for the automated generation of high-definition maps (HD maps), using technologies from GNSS, artificial intelligence and autonomous vehicles.[1].
Goals
The GAMMS project aims to develop an autonomous solution capable of acquiring geospatial data and producing HD maps with centimeter precision. These maps are essential for autonomous driving, urban air mobility, smart cities and augmented reality applications. Among its main objectives are:
Technology
The AMMS system integrates multiple sensors: inertial measurement units (IMU), odometers, atomic clocks and visual sensors (cameras and LiDAR), combined with multi-constellation GNSS signals to calculate the vehicle trajectory in terms of position, speed and orientation.[5].
GeoNumerics leads the development of navigation algorithms through the NEXA (path determination) and GENA (dynamic network adjustment) platforms. The use of Galileo-specific signals "Galileo (satellite navigation)") (E1, E5 AltBOC and E6) improves the accuracy of trajectory estimation.[6].
Integration with Galileo
GAMMS is one of the first projects to use HAS and OSNMA services for real mapping applications. These services offer global decimeter precision and message authentication at the signal level.[4].
The G3STAR GNSS receiver, developed by DEIMOS Engenharia, is capable of decoding Galileo HAS signals in the E6 band and validating OSNMA messages in real operational scenarios.[6].
Use cases
The GAMMS system is designed for applications requiring accurate maps, including:
Consortium
The project is coordinated by GeoNumerics (Spain) and has eight partners from five countries:
Financing
GAMMS is funded by the European Union Agency for the Space Program (EUSPA), within the Horizon 2020 programme, through grant agreement no. 101004255. The total budget exceeds €1.9 million.[1].
