1.1

RPAS - Remotely Piloted Aircraft System

FAA Definition: Remotely piloted Aircraft system operated by a pilot via ground control or on-board computer. 

Background Information

RPAS Categories

Small  

• Size: 1 - 2 meters ( 3 ft - 6.5 ft), < 55 lbs.
• Control: Visual line of sight, Radio control
• DJI M3E, M400,  ScanEagle

Medium

• Size: Equivalent to a car, ~ 1000 lbs.

Large 

• Size: > 30,000 lbs.

Two Spaces for Drone

Outdoor

Indoor

Outdoor

Indoor

• No GPS signal
• Limits on speed and motion
• Manual flight control
• Tight spaces

Outdoor

Indoor

DJI Air & Mavic 2 Pro < $1800

Aertos 120 $25,000 +

Eilos 2  $48,000 +

DJI Matrice 300 $12,000 +

RPAS as Platform

Multi-rotors

Fixed-wing & VTOL

• Shorter flight time (< 45 min)
• Cover smaller area
• Highly maneuverable
• Less expensive
• Access to confined spaces

• Long flight time (+ 40min)
• Covers very large area

(vertical take-off & land)

FAA Regulations - Where are we now?

Regulations

Commercial/Governmental

FAA Part 107 Rule, July 2016

• Need FAA Remote Pilot Certification (Pilot license NOT needed)

• ~460,375 - Remote pilots certified (Oct. 2025)

• 433,407 - Commercial Drones Registered (Oct. 2025)

• $175 to take the test

• Fly under 400 feet above ground level

• Not to fly < 5 nautical miles around airport

• Aircraft < 55 lbs.

• Fly during daytime or night time operation with appropriate lighting

• Fly visual line of sight ( VLOS)

• No flight over non-participating people

• ...and many, many more.....

FAA Part 107 Rule

FAA Part 107 Drone Certification

• Be at least 16 yrs old

• Pass the initial aeronautical knowledge exam

• Online recurring training every 24 month 

The Recreational UAS Safety Test (TRUST)

• Understand recreational flying requirements

• Take TRUST

• Online recurring training every 24 month

Part 1.1: Hardware

Flight Control App  

• Fly Consistently for overlapping images
• Can fly manually but it's like mowing with scissors

Structure from Motion (SfM)

Part II: Data Processing 

Photogrammetry

Part II: Data Processing 

Data Processing

Input Sequences in DD

Ground Control Points

Increase accuracy of drone map

GCP's make your map accurate BUT do not let you know HOW accurate the map is.

Ground Control Points

RTK = Real-Time Kinematic

RTK with Mobile Base Station

RTK with NTRIP

NTRIP - Networked Transport of RTCM (internet protocol). 

Require Constant Internet connection (cell) or subscrption

Ground Control Points

GNSS Receivers with RTK + 

Esri FieldMap

Importance of Check Points

• Check points are physical markers in drone images where the precise GPS location is known
• Check Points give XYZ error in inches/cm with map products
• Single or average error does not guarantee the accuracy for all parts map

• GCP = map processing

• Check Points = calculating average errors

Analysis Topic Examples

1.1

Data Processing

• Esri Dashboard with Survey123

GIS Integration

• AGO Web App

• AGO 3D Scene Viewer App

GIS Integration

DD 3D Model 

1. QGIS to georeference aerial imagery export to tiff file
2. Using GDAL
3. Or use mbutil to export into tiles

GIS Integration

• Create web-map using GitHub's gh-page

GIS Integration

DD GeoTiff -> gdal2tile.py -> tile folder
