Teledyne UK, the Chelmsford business formerly known as e2v, turns laboratory atomic physics into timing and gravity-sensing hardware. It led KAIROS, a £7 million Industrial Strategy Challenge Fund project (November 2018 to 2021) that took NPL's miniature caesium clock to pre-production as MINAC, now built at its Essex site with UK supply chains for key parts such as VCSEL lasers. In March 2022 the aircraft carrier HMS Prince of Wales sailed for an Arctic exercise carrying a quantum clock developed with Teledyne, and the company was the largest industrial participant in RSK's Pioneer Gravity cold-atom sensor consortium (2018 to 2021).
Teledyne UK, based in Chelmsford, is a company. It appears as a partner in Gravity Pioneer.
