Overview
The ZeroOne OneASP Ultra is an airspeed sensor designed for high-speed aircraft applications, providing reliable airspeed data for flight control systems. It supports a wide measurement range of 0~1636.9km/h (at 15C, 101325Pa standard atmosphere conditions) and uses DroneCAN bus communication for interference-resistant data transmission.
Key Features
- Wide airspeed measurement range: 0~1636.9km/h (at 15C, 101325Pa).
- Total error band: 0.25% FS.
- 24-bit ADC with built-in storage compensation.
- DroneCAN bus communication (designed for stronger interference resistance vs. traditional I2C).
- Flight controller compatibility: ArduPilot and PX4.
- Durable housing design: aerospace aluminum shell; silicone tube locking structure (as shown).
