  • Wind Estimation and Effects of Wind on Waypoint Navigation of Uavs
    Wind Estimation and Effects of Wind on Waypoint Navigation of UAVs by Anandrao Shesherao Biradar A Thesis Presented in Partial Fulfillment of the Requirements for the Degree Master of Science Approved April 2014 by the Graduate Supervisory Committee: Srikanth Saripalli, Co-Chair Spring Berman, Co-Chair Jekan Thanga ARIZONA STATE UNIVERSITY May 2014 ABSTRACT The presented work in this report is about Real time Estimation of wind and analyzing current wind correction algorithm in commercial off the shelf Autopilot board. The open source ArduPilot Mega 2.5 (APM 2.5) board manufactured by 3D Robotics is used. Currently there is lot of development being done in the field of Unmanned Aerial Systems (UAVs), various aerial platforms and corresponding; autonomous systems for them. This technology has advanced to such a stage that UAVs can be used for specific designed missions and deployed with reliability. But in some areas like missions requiring high maneuverability with greater efficiency is still under research area. This would help in increasing reliability and augmenting range of UAVs significantly. One of the problems addressed through this thesis work is, current autopilot systems have algorithm that handles wind by attitude correction with appropriate Crab angle. But the real time wind vector (direction) and its calculated velocity is based on geometrical and algebraic transformation between ground speed and air speed vectors. This method of wind estimation and prediction, many a times leads to inaccuracy in attitude correction. The same has been proved in the following report with simulation and actual field testing. In later part, new ways to tackle while flying windy conditions have been proposed.

  • Dead Reckoning Navigation
    Darren Smith, ATP, CFII/MEI Certificated Flight Instructor 813-503-3322 www.cfidarren.com FAA Pilot Education Pamphlet Reprints Dead Reckoning Navigation Are you ready to fall back to the lost art of compass and clock if your electronic aids fail? It is generally agreed that the compass is a pilot's primary navigation tool. But when it comes to specifying the second most valuable such device in the cockpit, there is often some difference of opinion. New pilots generally favor the VOR receiver. But those with more experience vote for the clock. After all, when a fuse blows or the left-right needle behaves like a metronome gone berserk, a pilot must resort to basics. The reliable compass and clock beomes his primary weapons in a battle of wits against the elements. The compass indicates where he's going and the clock tells him how far. Without either of these allies, a pilot can get lost, very fast, especially when above clouds or when over terrain where checkpoints are confusingly few and far apart. Compass-and-clock, or dead-reckoning navigation, however, is slowly becoming a lost art as increasingly more reliance is placed on electronic guidance. Although no one can deny that VOR navigation has simplified cockpit workloads, pilots must avoid becoming too complacent. Some, for example, don't keep track of their forward progress while navigating along a radial. They simply wait for the TO-FROM flag to drop, which may provide the first positive fix since passing the previous station. But shouldn't a pilot always know his position relative to the nearest airport? Dead reckoning, or DR navigation, is a relatively painless procedure that can and should be combined with radio navigation so that a pilot is aware of his approximate position at all times.

  • Dear Rod: Private Pilot Certificate Candidates Are Expected to Be Able
    Dear Rod: Private pilot certificate candidates are expected to be able to plan and execute a dead reckoning cross- country flight in which they prepare a flight planning log sheet and select checkpoints and calculate estimated times of arrival and fuel burn for each. Assuming a low cruising altitude, this is a relatively simple exercise for all checkpoints except the first one. For the first checkpoint, there is a climb segment and a cruise segment. For the remaining segments one can typically assume a constant altitude, airspeed, and fuel consumption rate. Now for my question. As an instructor, I'd like to know if there is a single, preferred technique that students can use to calculate the ETA and fuel burn for the first checkpoint. One rule-of-thumb method I've seen is to use the planned cruise airspeed and fuel rate for the entire first segment, and then add one minute for each thousand feet of climb, to account for the reduced airspeed and increased fuel burn during the climb. However, it would also be practical to use the performance charts to perform a more detained calculation, and there are flight-planning programs that will actually do so. The question is, what do examiners really want to see? Sincerely, M. Wilson Greetings M. Wilson: Here's my rule of thumb regarding rules of thumb: Use a rule of thumb on anything you desire except fuel burn, otherwise you'll be all thumbs when it comes to calculating the precise amount of fuel in your tanks. Yes, I know there are several rules of thumb floating around regarding fuel usage and time to climb.

  • Navigation Basics Reading Assignment
    Chapter 9 Spaceship Earth (EAA) “Navigation is the science of getting ships, aircraft or spacecraft from place to place . the method of determining position, course and distance traveled.” This is what one dictionary says about navigation. For purposes here, the dictionary’s definition will be simplified to say that navigation is knowing where you are, where you are going and how to get there. We could say that each of us navigates in order to get from place to place during our daily activities. In familiar territory, we navigate without thinking by following the right streets and making proper changes in direction to get to our destinations. If time is a concern, we estimate how long it will take us to travel the required distance. To assist navigational tasks, descriptive city and road maps are used when going into unfamiliar territory. Hunters, explorers and others going into unmarked territories use special types of maps (topographic) and direction-indicating instruments (compasses) to help them navigate through the territory. Aviators and seafarers are even more concerned with maps and direction-indicating instruments because they may not be able to see the land for long periods of travel. The aviator cannot simply stop by the local convenience store and ask for directions. Navigation principles are generally the same for any type navigation. They do, however, involve considerable detail when a navigation problem is complex. An examination of these basic principles is given in this chapter. However, remember that pilots must learn (and practice) much more than is discussed here. 235 Chapter 9.indd 235 1/9/08 11:07:24 AM bjectives Explain how a grid is constructed to provide a system of coordinates for use on a map.

  • CHAPTER 8 - NAVIGATION © Reilly Burke 2005 INTRODUCTION
    CHAPTER 8 - NAVIGATION © Reilly Burke 2005 INTRODUCTION This chapter provides an introduction to cross-country flying under visual flight rules (VFR). It contains practical information for planning and executing cross-country flights for the beginning pilot. Air navigation is simply the process of piloting an airplane from one geographic position to another while monitoring one’s position as the flight progresses. It introduces the need for planning, which includes plotting the course on an aeronautical chart, selecting checkpoints, measuring distances, obtaining pertinent weather information, and computing flight time, headings, and fuel requirements. The methods used in this chapter include pilotage—navigating by reference to visible landmarks, dead reckoning—computations of direction and distance from a known position, and radio navigation—by use of radio aids. AERONAUTICAL CHARTS An aeronautical chart is the road map for a pilot flying under VFR. The chart provides information which allows pilots to track their position and provides available information which enhances safety. The three aeronautical charts used by VFR pilots are: •VFR Navigation Charts (VNC) •VFR Terminal Area Charts (VTA) •World Aeronautical Charts (WAC) A free catalog listing all Canadian and US aeronautical charts and related publications including prices and instructions for orderingc VFR Navigation Charts VFR Navigation Charts are the most common charts used by pilots today. The charts have a scale of 1:500,000 which allows for more detailed information to be included on the chart. A distance of 1cm on the chart equals 500,000 cm, or 5km, on the ground. The charts provide an abundance of information, including airport data, navigational aids, airspace, and topography etc.

  • Don't to Math in the Cockpit
    DON’T TO MATH IN THE COCKPIT THE "M" WORD Notes in this column will be used The physical laws of the universe react precisely the same every to either interpret a concept, provide a “second opinion,” or time. Once we understand their process and relationship we can just offer a humorous example. predict how they will react to help us or do us harm. The bad news is that mathematics is very helpful in describing relationships in all aspects of science. The good news is that we are not going to memorize a bunch of formulas or do a bunch of math exercises. We assume you already know all the math you need. We will explain what we need as we go. There are several simple mathematical concepts we use in flying airplanes. Luckily these operations can all be done on the ground. From this point on, this should be our mathematical mantra - DON'T DO MATH IN THE COCKPIT. This means that we either have to do all our calculations ahead of time, find some job-performance-aids, or find some simple rules of thumb. Before we taxi out we must be sure we know: 1. which direction we should go? 2. how long it will take to get there? 3. how much fuel do we need? 4. do we have enough runway at both ends of the flight? 5. will we be within the weight and balance limits for the entire flight? We can use an E6-B air navigation computer to make these calculations. The E6-B is a hand-held “whiz wheel” developed in the early 1900’s.

  • Two-Stage Kalman Filter for Fault Tolerant Estimation of Wind Speed and UAV Flight Parameters
    MEASUREMENT SCIENCE REVIEW, 20 , (2020), No. 1, 35-42 Journal homepage: https://content.sciendo.com Two-Stage Kalman Filter for Fault Tolerant Estimation of Wind Speed and UAV Flight Parameters Chingiz Hajiyev 1, Demet Cilden-Guler 2, Ulviye Hacizade 3 1Istanbul Technical University, Faculty of Aeronautics and Astronautics, Istanbul, Turkey, [email protected] 2Istanbul Technical University, Faculty of Aeronautics and Astronautics, Istanbul, Turkey 3Halic University, Faculty of Engineering, Istanbul, Turkey In this study, an estimation algorithm based on a two-stage Kalman filter (TSKF) was developed for wind speed and Unmanned Aerial Vehicle (UAV) motion parameters. In the first stage, the wind speed estimation algorithm is used with the help of the Global Positioning System (GPS) and dynamic pressure measurements. Extended Kalman Filter (EKF) is applied to the system. The state vector is composed of the wind speed components and the pitot scale factor. In the second stage, in order to estimate the state parameters of the UAV, GPS, and Inertial Measurement Unit (IMU) measurements are considered in a Linear Kalman filter. The second stage filter uses the first stage EKF estimates of the wind speed values. Between these two stages, a sensor fault detection algorithm is placed. The sensor fault detection algorithm is based on the first stage EKF innovation process. After detecting the fault on the sensor measurements, the state parameters of the UAV are estimated via robust Kalman filter (RKF) against sensor faults. The robust Kalman filter algorithm, which brings the fault tolerance feature to the filter, secures accurate estimation results in case of a faulty measurement without affecting the remaining good estimation characteristics.

  • General Solution of the Wind Triangle Problem and the Critical Tailwind Angle Dr
    Minnesota State University, Mankato From the SelectedWorks of Nihad E. Daidzic, Dr.-Ing., D.Sc., ATP, CFII, MEI 2016 General solution of the wind triangle problem and the critical tailwind angle Dr. Nihad E. Daidzic Available at: https://works.bepress.com/nihad-daidzic/23/ General solution of the wind triangle problem and the critical tailwind angle Nihad E. Daidzic* AAR Aerospace Consulting, LLC, Saint Peter, MN, USA Email: [email protected] Submitted December 12, 2015 Abstract A general analytical solution of the navigational wind-triangle problem and the calculation of the critical tailwind angle are presented in this study among other findings. Any crosswind component will effectively create a headwind component on fixed course tracks. The meaning of a route track is lost with excessive crosswinds representing the bifurcation point between the possible and the impossible navigational solutions. Any wind of constant direction and speed will effectively reduce groundspeed and increase time-of-flight on closed-loop multi-segment flights. Effective wind track component consists, in general, of true and induced components. The average groundspeed of multiple-leg flights is a harmonic average. The critical tailwind angle measured from the positive true course (TC) direction will increase as the wind speed/true air speed (WS/TAS) ratio increases. The extreme case is when the wind correction angle is 90° in which case the airplane is oriented and flying perpendicular to the TC and the groundspeed (GS) is equal to TAS because of the true tailwind component. Relatively slow GA light airplanes could become very vulnerable to atmospheric wind effects as high WS/TAS conditions adversely affects flight safety.
