Phantom 4 RTK
DJIThe DJI Phantom 4 RTK is a discontinued (launched late 2018) professional-grade quadcopter purpose-built for high-accuracy photogrammetry and survey-grade mapping. It features a 1-inch 20MP CMOS sensor, an integrated RTK module delivering 1 cm + 1 ppm horizontal and 1.5 cm + 1 ppm vertical positioning accuracy, and supports both RTK and PPK workflows via RINEX output. The drone executes autonomous pre-planned mapping missions (waypoint-based) without a human performing the flight task, though a human operator must plan, set up, and monitor each mission. Community and independent sources confirm strong real-world accuracy but note reliability concerns with NTRIP connectivity, ~30-minute flight time limitations, and no hardware upgrades since launch.

Evidence-graded claims from the DJI deep report
DJI holds 70–80% of the global civil drone market and approximately 96% of the U.S. market (pre-FCC restrictions).
Multiple independent analyses and research sources [10][13][16] corroborate DJI's dominant market position, though the 96% U.S. figure is pre-restriction and current share post-FCC action is unverified.
from DJI deep report →The DJI Robomaster S1 supports full onboard autonomy via a ROS2-based stack, including zero-shot sim-to-real multi-agent reinforcement learning (MARL) policy transfer.
An independent academic paper from the University of Cambridge [21] confirms the Robomaster S1 was used as a customized research platform running a ROS2-based full onboard autonomy stack with successful sim-to-real MARL transfer, though this reflects research-lab capability, not a commercial product claim.

DJI claims the Lito X1 and Lito 1 feature omnidirectional obstacle sensing active down to 5 lux, and the Matrice 400 features power-line-level obstacle sensing.
Specs are sourced from DJI's own press releases [12] and official enterprise blog [7]; no independent third-party lab test or field validation of the 5-lux omnidirectional sensing or power-line detection performance has been identified in the dossier.
from DJI deep report →The DJI FlyCart 100 is a commercially deployed all-in-one intelligent drone delivery system.
The FlyCart 100 is listed on DJI's official website [1] as a product, but the dossier contains no independent evidence of commercial-scale deployment, customer outcomes, or regulatory approval for delivery operations in any jurisdiction.

DJI's Return-to-Home (RTH) and autonomous safety features are reliable across its consumer drone lineup.
Multiple independent community reports [30][31][33][35] document RTH failures, remote controller transmission failures at low altitude, and tracking failures in forested environments, directly contradicting vendor marketing of reliable autonomous safety features.
from DJI deep report →DJI has deployed 600,000+ agricultural drones across 100+ countries, saving 410 million tons of water and cutting 51 million tons of CO2 emissions.
These figures originate exclusively from a DJI Agriculture press release [11]; no independent verification of the deployment count, water savings, or emissions reduction figures is present in the dossier.
