Frequently Asked Questions
What is the Apogee-A?
Apogee-A belongs to Apogee series line of high performance, MEMS-based Inertial Systems which deliver exceptional orientation data in a compact package. It includes an Inertial Measurement Unit (IMU) and runs exclusive Extended Kalman Filter (EKF) algorithms.
What is the difference between an AHRS and an IMU?
An IMU outputs raw angular rate and acceleration, while an AHRS such as the Apogee-A runs onboard sensor fusion to output ready-to-use roll, pitch and heading — no external estimation algorithm required.
Where is the Apogee-A available?
The Apogee-A is available through Leo Drive in the following region: Turkey. For other regions, please contact Leo Drive.
How can I get the datasheet and technical documents for the Apogee-A?
