Aerospace
No matter if flight control or navigation, the attitude heading reference system can provide everything from an orientation solution, accelerations or rotation rates. High output data rates enable responsive flight control solutions. Onboard data recording allows OEMs and operators to optimize AHRS settings for specific applications or have a backup data recording solution in case of an anomaly. With its low mass, it can be installed on almost any UAV with as low as 0.5kg maximum take-off weight. Our professional edition is a drop-in replacement for legacy ARINC-429 AHRS units for navigation, flight control, and antenna-pointing applications.
Maritime
For navigation on the oceans or precise wave movement data requirements, the NINE AHRS can be deployed to provide accurate sensor data. Its small footprint, low weight and efficient power consumption allows equipping any ship, platform or buoy with an AHRS.
Linear acceleration and rotation rates are crucial for automated ship stabilization systems while magnetic heading data can be used to support navigation solutions with additional data. Characterizing waves and generating motion models is easy using acceleration and buoy orientation data. All of which are provided by the attitude heading reference system.
Light Weight Edition
Its low power consumption combined with rich interfaces, easy integration and low weight allows a wide range of use cases.
Professional Edition
An ARINC-429 interface and a rugged stainless steel enclosure make this AHRS an excellent option for professional use cases.
Custom Solution
Your needs are more specific? No problem, we can develop custom hardware and software for your use case. No need to compromise.
The NINEV04 Attitude Heading Reference System (AHRS) is available in two versions. The Light Weight Edition is intended for small unmanned aerial systems in mind. With less than 50 grams it can be integrated into almost any UAS size. It features modern interfaces like UART and CAN-Bus. Output data rates of up to 1 kilo hertz are possible. Settings can be changed using a convenient USB Type-C interface (USB 2.0). The unit stores a user configuration as well as backup factory settings. Recovery to factory settings is always possible. The AHRS compass comes factory calibrated. Calibration matrices can be adjusted using the configuration interface.
For professional applications the AHRS is also available in a rugged stainless steel enclosure. It features an ARINC-429 interface to be compatible with legacy avionics architectures. The output data rate can also be increased up to 1kHz. When using ARINC-429 the output data rate is limited to the output data rate of sent labels as defined per ARINC-429 Specification.
Features
Magnetic Heading data output helps your platform to stay on course. The AHRS uses modern micro magnetic field sensors to enhance its orientation estimation and provide accurate data to the used by the host.
Highly dynamic movements can be tracked and characterised with up to 2000 degrees per second of rotational rate sensing. The maximum sensing scale can be decreased in favour of sensing precision.
No matter how fast your vehicle accelerates, the AHRS can probably keep up. With up to 16 times the earths gravity in sensing scale. Unless you have a sounding rocket, this is probably your best choice.
A USB Type-C interface allows for easy configuration and saving new settings. In addition the same interface can be used to acquire data during system integration.
For ease of use, the DroneCAN protocol comes as standard with the CAN Bus 2.0B interface specification. The orientation solution, raw data and magnetic field strength are available via CAN Bus.
For anyone that requires a serial data transfer interface, the AHRS comes with a UART port implementing a custom protocol that has low overhead and is easy to parse.
