Vertical Gyros (VG)

Aceinna (formerly Memsic) Vertical Gyros are Six-degree-of-freedom (6DOF) strapdown inertial systems with Kalman filter & attitude algorithm for accurate roll/pitch measurements in dynamic environments.

Aceinna is a spin-off of Memsic Inc. a world leader in MEMS sensor technology.

Aceinna’s inertial systems provide end-users and systems integrators with fully-qualified MEMS-based solutions for measurement of static and dynamic motion in a wide variety of challenging environments, including avionics, remotely operated vehicles, agricultural & construction vehicles and automotive test.

The current vertical gyros series includes the VG280ZA, VG380ZA, VG380SA, VG350 and VG440.
