Effectiveness of Attitude Estimation Processing Approaches in Tolerating Radiation Soft Errors

چکیده
This paper compares the radiation-induced soft-error tolerance effectiveness of five different attitude estimation (AE) processing approaches that are classically used in inertial navigation systems (INS) autonomous things. Results 14-MeV neutron and thermal radiation testing campaigns indicate all AE investigated can be critically perturbed by single event upsets (SEUs), yielding inappropriate output data would place INS unavailable for a while. Moreover, results also suggest Kalman filter-based presented better effectivenesses tolerating SEUs than based on gradient descent.

Effectiveness of Software-Based Hardening for Radiation-Induced Soft Errors in Real-Time Operating Systems
For decades, radiation-induced failures have been a known issue for aero-space systems, in which redundancy mechanisms are employed as a protection method. Due to the shrinking of structures and operating voltages, these failures are increasingly becoming an issue even for terrestrial applications. Unfortunately, redundancy increases costs, area usage, and power consumption, which can hinder it...
متن کاملRadiation Measurement Technologies for Evaluating Soft Errors
Two radiation measurement technologies for estimating and lowering the occurrence rate of “soft errors” are introduced. Radiation such as fast neutrons (generated by cosmic rays) and α-rays (generated by the impurities in materials composing LSIs) cause incorrect operations—known as soft errors—in computer systems. Since soft errors undermine the reliability of mission-critical products such as...
متن کاملSoftware Mechanisms for Tolerating Soft Errors in an Automotive Brake-Controller
This paper describes the design and evaluation of two software implemented error detection and system recovery mechanisms that protect a prototype brakeby-wire controller from soft errors. We used an evaluation driven design process to develop the software mechanisms, which are specifically designed to prevent soft errors from causing critical failures in the brake controller. The design proces...
متن کاملTolerating Soft Errors in Processor Cores Using CLEAR (Cross-Layer Exploration for Architecting Resilience)
We present CLEAR (Cross-Layer Exploration for Architecting Resilience), a first of its kind framework which overcomes a major challenge in the design of digital systems that are resilient to reliability failures: achieve desired resilience targets at minimal costs (energy, power, execution time, area) by combining resilience techniques across various layers of the system stack (circuit, logic, ...
متن کاملOptimal Software Rejuvenation for Tolerating Soft Failures Optimal Software Rejuvenation for Tolerating Soft Failures
In recent studies, the phenomenon of software \aging" has come into light which causes the performance of a software to degrade with time. Software rejuvenation is a technique for fault tolerance which counteracts aging. In this paper, we address the problem of determining the optimal time to rejuvenate a server type software which experiences \soft failures" (witnessed in telecommunication sys...
