AirTheo “Autonomous solution to your surveying needs” Alex Zahn Brandon Kunkel Madison Fisher

Alex Zahn Aerospace Engineering Class of 2017 Our Team’s Mission: To take the risk out of land surveying and provide better information at a cheaper cost Alex Zahn Aerospace Engineering Class of 2017 Brandon Kunkel Aerospace Engineering Class of 2017 Madison Fisher Information Technology (Cyber Security) Class of 2020

Value Proposition Safety: Cost: Ease of Use: Safer way of surveying high risk areas (i.e. Post-disaster scenarios, mountainous terrain, etc.) Cost: Cheaper than utilizing helicopter/plane surveys Saves ground crews time Ease of Use: Compact/easy to transport Easy to set up Capable of multiple types of surveying

Operational Concept: Assumptions Sensors provide necessary precision Acceptable Weather Wind is under 35 mph Visibility of greater than 3 miles Survey site meets FAA regulations, or waiver can be acquired Every person on survey site is a willing participant Surveying takes place during day Landscape allows constant line of sight

Operational Concept: Mission Profile Arrive at survey site location. Unpack UAV(s) and CAL modules. Plug in sensors, batteries, etc. Turn on Ground Station, set # of AirTheos, choose survey area, and program develops flight path based on current topographical data. Options for manual flight path editing. Place UAV(s) on ground between calibration modules close to program specified distance. Calibration initiates and finds AirTheo location. Calibration is OK’d by ground station, surveying begins. UAV(s) slowly climb to 100 ft. and begin survey, capturing pictures and data, maintaining contact with calibration modules, and beaming location data to ground station. UAV(s) return to 100 ft. above ground station at end of calculated flight path, and slowly descend until touchdown. Collect data from UAV(s) and post process.

AirTheo Mission Profile UAV 1 UAV 2 START Flight Planning Google Maps API integrated into software package Designate area of interest (BLUE) Program calculates the optimal flight path (Orange) based on number of drones and Google Maps topography

Operational Concept: Ground Station CAL Calibration modules (CAL) maintain contact with each other and UAV during flight, enabling precise position monitoring Ground station coordinates with UAV and CAL modules during calibration and flight Ground station collects data via Ethernet from UAV upon mission completion ¼” is standard uncertainty in surveying measurements

Operational Concept: Ground Station Output 1. Data acquired from the survey can be processed in a variety of formats, for example: Colored point cloud Contour Map Vector Map Boundary Maps Difference Maps (erosion) Composite Map, “stitched images” 2. Possibilities of CAD file creation. Customer discovery suggested this was wanted. 3.

Operational Concept: Legal Issues Limitations: Must weigh less than 55lbs. Must remain in visual line-of-sight, with only the use of normal sight or corrective lenses of the remote pilot Must not be operated over any persons not directly involved in the flight Must only be operated in daylight Must yield right of way to other aircrafts Must stay under 400ft. Above ground level or within 400ft. of a structure Flying in Classes B, C, & D allowed with ATC permission Flying in Class G allowed without permission Must be at least 5 miles from an airport No pilot may act as pilot for more than one aircraft at a time May not fly unmanned aircraft from a moving aircraft May not fly the unmanned aircraft from a moving vehicle unless the population in the area is sparse Pilot may not operate the unmanned aircraft if they know or has reason to know of any physical or mental condition that would interfere with a safe flight Pilot must conduct a preflight check of the unmanned aircraft

Operational Concept: Legal Issues Steps to assure FAA authorized flights: AirTheo weight << 55 lbs. Ground Crew will provide line of sight Work with FAA to look into line of sight solutions for large areas Equipment designed to obtain results from authorized altitudes Demonstrate safe operation of measurement instruments

Operational Concept: Privacy Challenges: Avoiding negative public image pertaining to drone surveillance Providing correct information to the public (i.e. Operational transparency) Adjacent land owners privacy concerns Noise concerns

Operational Concept: Privacy Proposed Action: Communication and transparency will be key Website will explain the average survey process Flight planning will take into account property lines Notify any neighboring landowners of impending survey and get authorization waiver Time of survey checked with adjacent land owners and operational envelope reduces noise

Operational Concept: Maintenance Replaceable Parts: Battery Propellers Measurement Sensors Calibration Module Hardware (screws, nuts, bolts) http://dronesarefun.com/BatteriesForUAV.html

Operational Concept: Privacy 1946: Supreme Court confirmed that landowners have a right to prevent intrusions of airspace Landowners own the air above their property, it’s just not clarified how much and when the flight above private property is considered trespassing FAA — exclusive rights to regulate airspace above 500ft. Mostly concerned with flight safety States — may regulate airspace at lower altitudes More concerned with privacy and nuisance concerns Ex. California law: prohibits the taking of pictures of a person who has an “expectation of privacy”
