300 has proven itself in various high dynamic environments. Provide excellent results:
Red Bull Air Race
MotoGP car "gyro"
Reno Air Race
All kinds of drones are in-flight ADAHRS of the customer's own flight control computer.
The redundancy in the POLAR-300 software can avoid the failure of a single sensor. While maintaining accurate attitude and position estimates, the MEMS-based high-performance IMU is calibrated and compensated over the entire industrial temperature range.
Main features:
High-precision attitude estimation Accurate attitude determination is an important process for navigating and controlling an aircraft. Achieve excellent accuracy in evaluating attitudes. This is why we have spent years researching and developing aviation-grade sensor fusion evaluation algorithms.
Redundant IMU
Compact and easy to integrate
Packed in aerospace-grade aluminum housing.
It can be directly integrated into the customer's product as an OEM board.
As a professional autopilot developer and manufacturer, UAV Navigation strives to achieve the highest aviation standards in terms of product performance, accuracy and reliability. UAV Navigation's manufacturing plant is equipped with the most advanced calibration and measurement equipment. And all products shipped out of the factory have undergone thorough quality control inspections. Repeatability is the key. All equipment and instruments used in the manufacturing, calibration and acceptance test protocol (ATP) process comply with UAV Navigation's strict quality policy.
It combines excellent navigation and attitude performance with a wide range of high dynamic conditions and GPS rejection of navigation.
The quaternion-based solution avoids the universal joint problem encountered in legacy systems.
High data reporting rate from sensors to reduce latency. This is an important requirement of advanced control systems.
It is used as the onboard sensor unit in the VECTOR autopilot for UAV navigation.
