Inertial navigation and positioning systems are the basis for controlling vehicles such as aircraft, ships, or satellites. However classical inertial sensors suffer from device-dependent drifts and require GNSS corrections.

Satellite navigation (GNSS) possesses inherent limitations. Its signals are prone to natural or human-made interference. Besides no GNSS signal in some areas.

Hybrid quantum navigation, based on the combination of classical Inertial Measurement Units with quantum sensors based on atom interferometry are a serious candidate for a new technology that meets today's requirements for inertial navigation.

We present our latest activities to transfer a complex laboratory-based device to a robust and compact measurement unit that can be used in a dynamic environment to subtract the drifts of classical devices. Using a new laser system design with the latest developed electronics along with the implementation of new optics schemes and commercial compact vacuum system.
