Blood in 30 Minutes: Medical Drone Delivery's Proof Points—and Its Limits
Zipline's decade of operations across Africa has produced peer-reviewed evidence of reduced maternal mortality and vaccine stockouts. US hospital networks are building toward BVLOS corridors—but the FAA's case-by-case waiver system remains the binding constraint.

How Drones Rewrote Aerial Cinematography: From FAA Exemptions to FPV
From the FAA's first six commercial UAS exemptions in September 2014 to FPV drones threading car chases in major studio releases, drone technology has restructured what aerial cinematography can do — and who can afford to do it.

Drones at Sea: Emissions Policing, Hull Inspection, and Offshore Autonomy
Merchant shipping moves more than 80 percent of world trade behind a veil of opacity — corroding hulls, sulfur-burning engines, and expensive shore logistics. UAVs are now operational across four domains, from EMSA plume-sniffing campaigns to classification-accepted hull inspections conducted on vessels in transit.

Detect and Avoid: The Technology Standing Between Drones and the Open Sky
BVLOS operations at scale hinge on one unsolved problem: teaching drones to see and avoid other aircraft without a pilot's eyes. A look at the cooperative and non-cooperative sensing, competing standards, and hardware programs racing to close that gap.

The Full Attack Surface: How UAS Systems Get Compromised
From command-link hijacking to GPS spoofing and supply-chain malware, every layer of a drone system is a potential entry point. Here is how the attack surface breaks down—and what serious operators are doing about it.

How Drone LiDAR Works: Pulses, Point Clouds, and the Navigation Stack Behind It
Drone LiDAR fires millions of laser pulses per second and rebuilds the physical world as georeferenced 3D coordinates. Here is the physics-to-deliverable chain, from waveform digitization and boresight calibration to centimeter-accurate corridor surveys.

Inside the Drone Power Chain: Motors, ESCs, and Propellers Explained
Every multirotor's performance comes down to three linked components — brushless motor, electronic speed controller, and propeller. Understanding how they interact, and where electric propulsion hits its ceiling, is essential for anyone building or specifying UAS.

How GPS Spoofing Hijacks Drones — and Why It's So Hard to Stop
GPS spoofing doesn't jam a drone's navigation — it replaces it. By feeding counterfeit satellite signals a receiver accepts as legitimate, an attacker can redirect an aircraft mid-flight without triggering a single alarm. Here's how the attack works and what defenses exist.

Multirotor vs. Fixed-Wing vs. Hybrid VTOL: Engineering Tradeoffs for Every Mission
Every drone airframe resolves the same core tension: hover capability costs endurance, endurance costs hover. A physics-first breakdown of how multirotors, fixed-wing platforms, and hybrid VTOLs make that tradeoff — and which missions each class actually wins.

Centimeter Accuracy from Altitude: How Drone Photogrammetry Actually Works
A drone at 100 meters can produce a map accurate to 1.5 centimeters — if the math of overlap, ground control, and software choices all align. Here is what drives that number and where it breaks down.

How RTK and PPK Give Drones Centimeter-Level GPS Accuracy
Standard GPS gets you within a few meters. Drone surveyors need centimeters. RTK and PPK achieve that by exploiting carrier-phase measurements — a technique roughly 100 times more precise than the code-based ranging your phone uses.

UAS Traffic Management: The Decentralized Architecture Replacing ATC Below 400 Feet
The FAA provides no air traffic services below 400 feet, where drone density is set to explode. UAS Traffic Management replaces centralized control with a federated network of software intermediaries — and a decade of NASA research shows why that architecture is the only one that can scale.
