In this paper, an affordable and reliable low-cost inertial measurement unit (IMU) is designed using commercial off-the-shelf (COTS) components. Micro electro-mechanical systems (MEMS) accelerometers and rate-gyros are used, and a methodology for calibrating the resulting IMU is developed when the precise orientation of the IMU is unknown. The proposed(More)
An Unmanned Aircraft System (UAS) collision avoidance algorithm for the Sense and Avoid (SAA) problem is proposed. The avoidance path is modeled using a physical analogy of a chain placed in a force field. This approach has the advantage that it continuously searches the space for a proper evasive maneuver to avoid an impending collision with detected(More)
The airborne collision detection is a challenging problem due to inherent noise in onboard sensor(s), limited computational resources available for unmanned aircraft system and variability in intruder dynamics resulting in uncertainty in predicting intruder future trajectories. In this paper, we develop an innovative approach to quantify likely intruder(More)
