Abstract: Motivated by the opportunity to develop industry pull applications and services for the European EGNOS and GALILEO satellite systems, within SPARTACUS project are being tested satellite based positioning units aided by small inertial navigation platforms. In particular, three different types of tracking units were designed and realized for: (i) freight trains tracing, (ii) relief goods distribution, and (iii) coordination of first responders. In order to improve the positioning accuracy in presence of several units installed on the same convoy, were developed software solutions based on two steps (low and high level) in order to allow the integration of information collected by the individual tracking unit and by the whole array of sensors.
Abstract: This work describes the activities and the results achieved within the SPARTACUS project with regards to the development of a pedestrian positioning system for first responders based on inertial sensors and GNSS data integration. In particular, three steps have been dealt with. At first the analysis of a typical human motion profile, highlighting the Zero Velocity Update constraints; secondly, the definition of a high accurate reference trajectory for test validation purposes, with both indoor and outdoor tracks. Finally, the tuning of Extended Kalman Filter parameters for the calibration of the best sensor data fusion algorithm mainly focused to dead reckoning positioning and field test result assessment.
Abstract: The EU funded SPARTACUS project pursues the implementation of a small size, low-power consumption, tracking-unit integrating satellite receiver and antenna with terrestrial inertial sensors, enabling a dead reckoning functionality. In case of a good GNSS signal coverage, precise positioning and timing capabilities of the system are double-checked, while the positioning accuracy for dead reckoning has to be validated. In this paper, the results of field tests simulations are presented in order to validate the positioning performance in the absence of the GNSS signal. Two goals are pursued to secure tracking and functionalities customized for: (i) critical transport assets, and (ii) flow of relief support goods from the sending side to the receiving place.
