Visible to the public Situational Awareness Strategies for Autonomous Systems in Dynamic Uncertain Environments

Abstract: An event-based communication strategy for navigation using signals of opportunity (SOPs) in a collaborative radio simultaneous and mapping (CoRSLAM) framework is developed. The following problem is considered. Multiple autonomous vehicles (AVs) with access to global navigation satellite system (GNSS) signals are aiding their on-board inertial navigation systems (INSs) with GNSS pseudoranges. While navigating, AV-mounted receivers draw pseudorange measurements on ambient unknown terrestrial SOPs and collaboratively estimate the SOPs' states.

Historically, software assurance technologies and robust fault-tolerant control (RFTC) theory were developed under different assumptions and models. The software assurance technologies are often model-based that require the profile of the physical dynamics and the observation of the system state, which may not be available when physical defects exist. On the other hand, though the existing RFTC techniques can efficiently compensate for the physical damage, it is critical to guarantee that the control software and the sensor data are not compromised.
