Today, precise inertial navigation and positioning systems are the basis for controlling vehicles such as aircrafts, ships, or satellites. However classical inertial sensors suffer from device-dependent drifts and require GNSS corrections that themselves rely on the availability of the signal broadcasted by the satellites. This leads to the non-usability of classical sensors in some environments like in-between buildings, underground, or space.
Hybrid quantum navigation, based on the combination of classical Inertial Measurement Units with quantum sensors based on atom interferometry, is a serious candidate for a new technology that meets the demand of our time requirements for inertial navigation.
Atom interferometers have proven to measure drift-free at very high sensitivities. The main challenge is to transfer a complex laboratory-based device to a robust and compact measurement unit that can be used regardless of their small bandwidth and dynamic range to subtract the drifts of the classical devices. We present the current status of our teststand for a quantum accelerometer employed on a gyro-stabilized platform.
