LOw cost GNSS Attitude and navigation system with inertial MEMS aiding

LOGAM project, namely Low cost GNSS attitude and navigation system with inertial MEMS aiding, is a project inserted on the SEVENTH FRAMEWORK PROGRAMME seeded by the European Commission.

The aim of the LOGAM project is to provide a high precision, low cost, low weight attitude and position sensor based on mass market devices supported by specific algorithms. Aermatica, designer and producer of small UAS, have been chosen as driver for the development of such device, highlighting the importance of such high accuracy, low weight and low prices devices on the UAS world.

LOGAM system mainly consists into a set of 4 GNSS receivers, a MEMS IMU, and an optional barometer blended together in order to achieve the position/attitude solution with a precision equal or better to higher prices devices. In days where GPS spoofing is an extremely hot topic in the UAS world, LOGAM project shines for its immunity to such technique due to the advanced algorithms adopted.

Being driven by Aermatica UAS application, the first rotary wing RPA (remotely piloted aircraft) to have obtained official permission to fly (Permit To Fly) issued in Italian civil airspace, the LOGAM system is designed in order to fulfill all the safety requirements needed on a regulated system. Its robustness comes from the architectural choices that position the LOGAM system at the top of the position/attitude sensors. LOGAM project involves key actors of the industry and academic world, creating the needed synergies for a state of the art system:

 Aermatica S.p.A. – system requirements, system tester, first end-user
 Acorde Technologies S.A. – complex system integration, technology gap analysis, HW elements selection
 Commissariat a l’Energie Atomique – antennas selection, characterization and calibration
 Istituto Superiore Mario Boella – attitude / position algorithms
 Fundación Centro Tecnológico de Componentes – attitude / position solution implementation
LOGAM UAVS-Article A01 Version 1.0

The first LOGAM prototype will show its capabilities being mounted on a small UAS, Aermatica Anteos, being a quadrotor weighting less than 7 kg. This high demanding platform will prove the LOGAM system efficiency where position and attitude information are key elements. An UAS completely relies on such information to achieve a safe flight, ANTEOS, being the first rotary wing UAS to receive an official permission to fly in Italy, can then be the optimal benchmark for the proofing of the reliability of the LOGAM system and its consequently adaptability on the new coming regulated UAS world.
