A path to standalone personalised navigation system

The introduction of GNSS (global navigation satellite systems), and specifically the GPS system, have allowed humans to travel in formerly unknown environments with relative ease. While these devices offer a great deal of functionality, they only represent the tip of the iceberg in terms of the potential of future personal navigation devices (PNDs). The goal of this project is to develop functional inertial navigation devices that can operate independent of any radio or satellite signals, in turn solving many of the limitations of GNSS based PNDs. By combining a robust on-chip controls algorithms, motion kinetics, microprocessor, MEMS based inertial measurement units (IMUs) and a variety of other sensors, it is possible to accurately track users and can offer personalised aided navigation in all environments. There is an endless list of potential applications for such standalone navigation system including for first responders, utility workers, mining workers, underwater divers and military personnel.

MEMS Inertial Measurement Units for Sensing Vehicle Dynamics

MEMS based accelerometers are by far the most commercially successful MEMS sensor in automotive applications. These sensors are typically used for safety applications (sense crashes and deploy airbags). However, we are using MEMS inertial sensors in significant other places in vehicles, for example, vehicles tilt/roll detection, embedded navigation or tracking, tow away detection and slide detection. In these applications, a single MEMS Inertial Unit are used. We are developing fully integrated and high precision MEMS Inertial Units for automotive dynamic motion sensing and vehicle stability applications.

Tactical-Grade MEMS Inertial Measurement Unit (IMU) for Aerospace

MEMS market is increasingly growing thanks to the reduction in size, cost, weight and power via wafer scale mass manufacturing. However, tactical grade MEMS IMU is still at its infancy because of sensor low sensitivity and drift. High end sensor manufacturing using conventional silicon MEMS are still challenging because of the need for extreme accuracy in silicon micro-manufacturing and limitations from inherent material properties. In this research, high precision fabrication from fused quartz is combined with advanced mechatronic principles are used to develop tactile grade sensors. The key pivotal element in achieving tactical-grade MEMS IMU requires addressing mechatronic principles to improve sensor stability, long-term sensor drift, on-chip calibration, temperature sensitive, stability and environmental performance, which are addressed in this research by developing advanced algorithms, controls and,electronics.
