Technical specifications

Body material:

Multilayer carbon, anisotropic structure + PEI impurities. Fastening from below surface on additional dampers, for vibration isolation.

Dimensions:

W x L x H: 150 x 134 x 73 mm

Weight:

The entire system, including our IMU, Al-powered flight control and light composite enclosure, weighs only 800g, making it lightweight and easy to install on various types of UV platforms.

Power:

Standard +5V power supply
Max current consumption: 10A, peak of 12A, 50W, Voltage/rated input current: 4.1-5.7 V / 2.5 A,
Output/input power: 14 W, USB port voltage/rated input current: 4-5.7 V / 250 mA,
Servo rail input voltage: 3.3 V / 5 V

Included Sensor Array:

Accelerometer, Gyroscope, Compass, Barometer, Multi-vector Airflow (Bavovna H-INS also allows the input of existing onboard sensors)

Connectivity:

Bavovna seamlessly connects to power, CAN, PWM, RF comm, GPS, optical flow, and other sensors, providing flexibility and compatibility across UV platforms

Mission Planner:

The Bavovna Mission Planner displays Bavovna as an optional Al-powered navigation system to allow mission execution through GPS-denied / EW-threatened areas while offering an advanced API and Ul based on the Ardupilot open-source platform

Flight Controller:

Bavovna uses PX Cube as an internal flight controller, ensuring reliable and accurate control of UVs. Bavovna can also output synthetic GPS coordinates directly into your platform’s existing flight controller

EMI-protected Case:

Bavovna’s EMI-protected case has undergone EMF resistance tests, ensuring reliability and durability in a variety of conditions.

End Point Positioning Error (EPPE):

The range of EPPE is minimal with simple trajectories, without additional maneuvers. On a sophisticated trajectory, Bavovna maintains an EPPE < 0.5% at a range of 30 km.

SIGINT RF and Other Modules:

Bavovna H-INS-powered vehicles can be integrated with various payloads, including radio repeaters, sensors, and SIGINT RF modules, allowing various mobile ISR and engagement capabilities in aggressive EW environments

No maps required:

The Bavovna system does not rely on power-hungry computer vision or unreliable maps of the flight environment

Hybrid systems can be affected by the combined errors of the systems they integrate, especially if one system’s errors are not adequately compensated by others.
Using continuous ML decreases the error rate.
