Precise inertial navigation and positioning play a determining role in our daily life. Actual navigation systems cannot be used for certain fields since they suffer from device-dependent drifts, requiring GNSS correction that is not possible for example in buildings or space. Therefore, solutions based on a new technology had become a huge demand.
Quantum hybrid navigation combines conventional Inertial Measurement Units with quantum sensors based on atom interferometry. Atom interferometers have proven to measure drift-free at very high sensitivities. They can be used regardless of their small bandwidth and dynamic range to subtract the drifts of the classical devices.
This combination proposes a better performance and security for traditional navigation domains and an efficient tool to explore inertial measurement in new areas. We present the current status of our test stand for a quantum navigation system employed on a gyro-stabilized platform.
