Customer Case | Solving Low-Altitude Test Challenges: NGI Full-Stack Solutions Empower World-Leading Drone/eVTOL Manufacturers

With low-altitude economy officially written into China’s national strategy, drone and electric vertical-take-off-and-landing (eVTOL) markets are exploding. CAAC data show the sector reached RMB 670 billion in 2024 and is forecast to hit RMB 3.5 trillion by 2035.

NGI’s high-performance instruments andfull-stacksolutions already support world-top players at every stage—from PCBA and sub-modules to complete vehicle certification. Below are selected customer stories and applications.

Case 1 – Flight-Control PCBA Functional Test for a Top Drone Manufacturer

Customer Requirement

Customer A, a global pioneer in spatial intelligence, produces drone systems, handheld imaging devices and educational robots. Their R&D team needed a compact test rack to validate flight-control PCBA functions: PWM control verification (motor speed&servo angle),Digital I/O checks (telemetry and on/off signals),Individual ESC-branch current measurement.The conventional setup—bench DMMs plus standalone digital-I/Omodules—took too much space and was difficult to integrate.

NGI Solution

To meet the customer’s upfront requirements, NGI proposed its NXI modular-platform solution. A single 3Uchassis integrates high-speed digital I/O,multiplexing and multi-channel current-measurement modules, cutting rack space by >40% and providing unified software control.

Case 2 – Power-Supply Validation for eVTOL Flight-Control Mainboard

Customer Requirement

Customer B, Asia’s largest flying-car company and a global top-tier eVTOL OEM, is developing smart electric aerial vehicles for personal transport.

During R&D they need to verify the flight-control mainboard’s behavior under wide-range DC inputs: over-voltage, under-voltage anddrop conditions. The test bench must deliver high accuracy, easy integration and rich sequencing features.

NGI Solution

To meet customer requirements, NGI offers the N36200 series of wide-range DC power supplies. Featuring high precision, easy integration, and rich functionality, these products perfectly match client verification and production line testing needs.
