PERFORMANCE CHARACTERISTIC MEMS-BASED IMUs FOR UAVs NAVIGATION

Based Navigation for UAVs

Most UAVs (Unmanned Aerial Vehicles) today use the GPS (Global Positioning System) for navigation. While GPS is an accurate and usually reliable aid to navigation, it can be unavailable for various reasons. The aim of this project is to develop an alternative navigation method, which can be used when GPS transmissions are not available. The method suggested here is called Feature Based Navigati...

Recent Advances in Accuracy Enhancement of MEMS-based IMUs for Navigation Applications

Many land vehicles are presently equipped with on-board navigation systems that currently rely entirely on the availability and accuracy of GPS. The accessibility of low cost MEMS-based inertial measurement units (IMU) can be used to provide precise position and velocity data for GPS signal acquisition and reacquisition after outages. This reduces the time and the search domain required for det...

Benefits of Combined GPS/GLONASS with Low-Cost MEMS IMUs for Vehicular Urban Navigation

The integration of Global Navigation Satellite Systems (GNSS) with Inertial Navigation Systems (INS) has been very actively researched for many years due to the complementary nature of the two systems. In particular, during the last few years the integration with micro-electromechanical system (MEMS) inertial measurement units (IMUs) has been investigated. In fact, recent advances in MEMS techn...

Reliability Testing Procedure for MEMS IMUs Applied to Vibrating Environments

The diffusion of micro electro-mechanical systems (MEMS) technology applied to navigation systems is rapidly increasing, but currently, there is a lack of knowledge about the reliability of this typology of devices, representing a serious limitation to their use in aerospace vehicles and other fields with medium and high requirements. In this paper, a reliability testing procedure for inertial ...
