The long-term objective of our research is to develop a method for infrastructure-free simultaneous localization and mapping (SLAM) and context recognition for tactical situational awareness. Localization will be realized by propagating motion measur

Today's society is highly reliant on time and frequency synchronization, e.g., in communications systems and financial networks. Precise timing is more and more derived from satellite navigation receivers that are unfortunately very susceptible to va

Satellite navigation has become a widely used resource in many fields. However, satellite signals are vulnerable to different interference sources, both intentional and unintentional. In safety critical situations such as rescue and tactical operatio

Precise positioning using Global Navigation Satellite System (GNSS) requires the GNSS receivers to compensate for the errors caused by distortion in the GNSS signal's path due to atmospheric conditions. The Real Time Kinematics (RTK) technique uses t

In this paper, we study machine learning methods for recognizing the motion context of a user of an infrastructure-free navigation system. Motion context is information about whether the user is running, crawling, or lying down, for instance. This ca

Proceedings of the 32nd International Technical Meeting of the Satellite Division of The Institute of Navigation (ION GNSS+ 2019).
This paper presents a hybrid navigation algorithm based on loose coupling of the on-board speedometer and inertial sensors of a land vehicle with a GNSS receiver. An Extended Kalman Filter estimating ten error states is used as the hybridization fram

The knowledge of orientation of an object with respect to earth-fixed reference coordinate system is crucial in many applications. For instance, in oil mining it is very crucial to accurately know the orientation of the drilling equipment under the e
