Wide area augmentation of the Global Positioning System
TL;DR: The Wide Area Augmentation System (WAAS) is being deployed by the Federal Aviation Administration to augment the Global Positioning System (GPS) and will provide an accurate position fix from satellites to an unlimited number of aircraft across the nation.
Cybernetics of Tunnel-in-the-Sky Displays
TL;DR: The experiments show that the cybernetic, information-centered approach is indeed very successful in pin-pointing the important characteristics of pilot/display interaction, based on a theoretical analysis of information, in particular the information used for control.

Localization Requirements for Autonomous Vehicles.
Tyler G. R. Reid,Sarah E. Houts,Robert Cammarata,Graham Mills,Siddharth Agarwal,Vora Ankit Girish,Gaurav Pandey +6 more
TL;DR: In this article, the authors derived the safety integrity level, defining the allowable probability of failure per hour of operation based on desired improvements on road safety today, and then defined the geometry of the problem, where the aim is to maintain knowledge that the vehicle is within its lane and to determine what road level it is on.

TL;DR: This work defines the geometry of the problem, where the aim is to maintain knowledge that the vehicle is within its lane and to determine what road level it is on, and derivesitudinal, lateral, and vertical localization error bounds and 95% accuracy requirements for autonomous vehicles based on first principles.

Availability Impact on GPS Aviation due to Strong Ionospheric Scintillation
Jiwon Seo,Todd Walter,Per Enge +2 more
TL;DR: A modification to the upper bound of the allowed reacquisition time for the current Wide Area Augmentation System (WAAS) Minimum Operational Performance Standards (MOPS) is recommended based on the availability analysis results and observed performance of a certified WAAS receiver.

The Probability Approach to the Treatment of Uncertainty in Artificial Intelligence and Expert Systems
TL;DR: Arguments are adduced to support the claim that the only satis- factory description of uncertainty is probability, and a challenge is made that anything that can be done by alternative methods for handling uncertainty can be do better by probability.

Long-Tailed Distributions for Position Errors in Navigation
TL;DR: In this article, a distribution theory is developed to explain a fairly well-established characteristic of the position errors observed in large navigation systems, and the empirical adequacy of the suggested model is compared with other existing models using newly collected data.
RNP Tunnel Concept for Precision Approach with GNSS Application
Jerald M. Davis,Robert J. Kelly +1 more
TL;DR: In this article, a methodology to determine the required navigation performance (RNP) for the tunnel concept is described, and the tunnel RNP for the precision approach phase of flight is determined using GNSS as the navigation system.
Mls system error model identification and synthesis
TL;DR: Signal-in-space modeling of approach and landing guidance systems such as the microwave landing system (MLS), which is necessary for aircraft certification, is addressed and a technique which can, in principle, identify the error sources in navigation systems and perform the inverse operation of synthesizing an error generator whose output is statistically equivalent to the original error data is described.

MLS system error model identification and synthesis
TL;DR: In this paper, the authors present a technique to identify the error sources in navigation systems and perform the inverse operation of synthesizing an error generator whose output is statistically equivalent to the original error data.
