Abstract [en]

In this paper we examine the effect of introducing an opportunistic cooperative navigation approach between soldiers, or first responders, equipped with foot-mounted IMUs and UWB-ranging equipment. The foot-mounted navigation system is based on a 15-state Extended Kalman filter, utilizing zero-velocity updates. The addition of range measurements between cooperative units displayed a significant improvement of the navigation accuracy in the studied scenarios. This approach has the potential to enable accurate positioning for several minutes in GPS-denied environments. Furthermore, the performance of the UWB-ranging sensor is examined and the resulting error statistics and typical ranging distances are characterized in indoor environments.
