Inertial navigation company iXblue is leading a NAVISP project consortium to develop a compact 3-axis Cold Atom Interferometer sensor, aimed for use aboard boats, aircraft and boats as well as at fixed sites. Cold Atom Interferometers (CAIs) are based around a few hundred thousand atoms at a time, trapped by a combination of lasers and magnetic fields. Atoms freefalling in an ‘quantum superposition’ states – meaning they are existing in several separate quantum states at the same time – are then interrogated by a laser to derive their interference patterns – revealing for instance gravity or other forces acting upon them. CAIs and comparable quantum technology can operate independently from satellite navigation with extremely high performance levels – the challenge is to get them working reliably and robustly outside of lab environments. This project is supported through ESA's NAVISP programme.
