The main objective of the LOGAM project is the design and development of an ultra low-cost attitude determination and navigation system based primarily on non dedicated mass market GNSS receivers and antennas and aided by MEMS inertial sensors. Accuracy at low cost is needed in various real-time applications such as vehicle tracking, unmanned aerial vehicles (UAVs), etc… Making use of the complementary characteristics of GNSS and INS derived measurements GNSS/INS integrated approach yield navigation solutions with improved performance. However to open the way for its widespread use the embedded applications require not only accurate position and attitude information, but also strictly real time abilities, such as system efficiency, reliability and feasibility as well as the size, consumption and cost. At the end of the project our aim is to produce a functional prototype capable of demonstrating the targeted system characteristics fitting with a great number of present and future applications.
The main gaps to be filled within LOGAM are:
• No low-cost GNSS-based attitude determination systems available in the market
• Size and weight reduction over existing platforms
• Development of a methodology for automated antenna calibration for this application (phase centre characterization)
At the end of the project our aim is to produce a functional prototype capable of demonstrating the targeted system characteristics fitting with a great number of present and future applications. In order to give to the project tangible and marketable results a first end-to-end application for the system has been identified (and will be built) in the small unmanned aerial vehicle guidance, navigation and control applications domain where minimal cost, weight and power consumption are critical. In particular the system will be integrated in small rotary wings UAV to provide data for automatic attitude and position control.
The goal of the LOGAM project will be the development of a new prototype of GNSS attitude system with inertial sensor aiding for navigation, focusing in the achievement of the best possible performance with the lowest cost, enabling its use in a plurality of applications. The small UAV demonstration application has been chosen as it is one of the most demanding in terms of performance, low power and low weight requirements
