Requirements — REQUIREMENTS for Commercial Inspection Drone [general]

Provide a commercial inspection drone solution to meet market demand for rapid aerial infrastructure inspections.
Achieve $5M revenue within two years through sales of at least 200 units.
Ensure compliance with Blue UAS program and NDAA Section 848.
Offer a competitive price point of $12,000 or less per unit.
Provide a BVLOS-capable platform with an operational design domain up to 30 km line-of-sight and 120 m altitude.
Drone shall achieve a minimum flight endurance of 45 minutes while carrying a payload of up to 1.5 kg under standard atmospheric conditions (ISA sea level, 15°C).
Drone shall integrate a dual-sensor gimbal containing a 4K thermal camera and a 12 MP RGB camera, allowing simultaneous capture and synchronized data logging.
Drone shall provide centimeter-level positioning accuracy (≤2 cm horizontal, ≤3 cm vertical) using RTK GNSS corrections.
Airframe shall meet IP54 protection rating to guard against dust ingress and water spray from any direction.
Drone shall be certified as a Blue UAS system and contain no prohibited components per NDAA Section 848.
Drone shall support BVLOS operations within an ODD of up to 30 km line‑of‑sight distance and a maximum operating altitude of 120 m AGL.
Drone shall provide two independent communication links (4G LTE and 900 MHz FHSS) with automatic failover within 1 second.
Drone shall execute autonomous takeoff, waypoint navigation, and safe abort landing under all operational conditions, with a built‑in “Return‑to‑Home” (RTH) behaviour.

Bill of Materials (BOM) target ≤ $8,500 per unit; total manufacturing cost ≤ $3,000 per unit.
Obtain FCC, CE, and Blue UAS certifications; no prohibited components per NDAA Section 848.
Prototype delivery Q4 2026; certification Q2 2027; production start Q3 2027.
Operating temperature -20 °C to +45 °C; wind up to 12 m/s; humidity 95 % non‑condensing.
Battery Energy Density Shortfall
Single‑Source RTK Module
