Veronte Autopilot 4x
Veronte Autopilot 4x is a redundant control system for critical operations such as UAM, eVTOL or MALE, HALE and Tactical drones. Fail-operational redundant autopilot architecture has been designed for avoiding single point of failure, all this included in a miniaturized autopilot managed by a dissimilar arbiter board.
Configurable control software makes Veronte Autopilot 4x compatible with all kinds of vehicle or aircraft layout. DO178C / ED-12 and DO254 aviation standards compliance is maintained in all configurations, enabling UAV, RPAS and UAM certification. Environmental DO160 / MIL-STD-810 test compliance data pack and MTBCF is also available for entering a certification process.

Veronte Autopilot 4x includes a series of tools for the customization of the control and navigation strategy. The Programs module permits to generate block diagram flows for defining the control laws and other programs in the system. Block libraries like PIDs, Adaptive Control, Energy Control, maths and logical operations are available.
In configurations where onboard computer vision or extended data processing capacity is needed, it is possible to interface a Mission Computer with the Veronte Autopilot 4x. It permits to exchange telemetry data between both computers and send commands and routes to the autopilot from the external source.

Redundancy and high-reliability assurance is a must when doing manned flight operations or flying over populated areas. For this, Veronte Autopilot 4x is the first drone and eVTOL autopilot including 4x redundancy and compliance with the DO178C and DO254 aviation standards up to DAL-B (DAL-A Ongoing).
For eVTOL operations, Veronte Autopilot 4x can be directly connected to an onboard stick and a mission computer running the user interface. Buttons and sticks can also be connected, configuring a custom aircraft cabin. Flight modes can easily be configured according to pilot skills and aircraft capabilities.

Veronte Autopilot 4x has been successfully installed in a wide range of Tactical, MALE and HALE UAVs. This redundant control system includes advanced tools for these scenarios, such as, fly-by-camera or communications silence. Fully autonomous operation from vessels or moving vehicles is possible thanks to the Rendezvous and Relative Mission algorithms.

Redundancy
Redundancy
Veronte Autopilot 4x is the redundant version of the Veronte Autopilot 1x. It embeds three complete autopilot cores plus one dissimilar arbiter board managing the redundancy. This redundant flight controller has been designed so there is no single point of failure and custom voting strategies can be configured.
An external autopilot core can be installed by connecting it to the multiplexing stage and entering to the voting strategy. The 4th core can be configured as the main flight computer so the Veronte Autopilot 4x acts as a FTS solution or it can be a dissimilar backup unit.

DO178C / ED-12 and DO254 aviation design standards are followed during the Veronte Autopilot 4x development (DAL-B). It permits to ensure the hardware and software reliability in the redundant autopilot for eVTOL and UAV certification. In addition, DO160 and MIL-STD-810 test permits to ensure robustness to adverse environmental conditions.
A robust Acceptance Test Procedure (ATP) is followed during the manufacturing process. Environmental Stress Screening (ESS) phase subjects the autopilot to temperature and vibration cycles for the detection of latent failures. This documentation, together with the DO Certification Data packs provides the evidence needed for UAV or eVTOL certification.

In these applications where failure is not an option, Veronte Autopilot 4x includes extended reliability and fail-operational functions. The automations module in Veronte permits to customize the aircraft performance upon a system failure or a risk to the operation (Low battery, datalink loss, GNSS loss, obstacle detection, flight envelope…).
Onboard and control station data loggers are available within the autopilot and in the control station for post flight analysis. In addition, the eVTOL and UAV flight controller includes: worldwide DEM, curve based navigation, GNSS-attitude estimation, relative missions, RTK, adaptive control, sensor fusion, situational awareness, fly-by-camera…
Long Range Operations
Long Range Operations
A wide variety of communication channels can be used for interfacing the Veronte Autopilot 4x with the GCS (Ground Control Station). Veronte Tracker is the prefered solution for long range communication but third party LOS, 4G/LTE and Satcom datalink modules can be used for communications with no range limitations.
The use of Veronte Cloud and the embedded 4G module in the UAV / eVTOL control system enables UTM integration by interfacing with online databases for air traffic and weather information. Sense & Avoid functions are also possible by installing an obstacle data source, such an, ADS-B, a radar or a LIDAR sensor.
