France’s Safran Group last Friday said it has acquired Orolia, a provider of resilient positioning, navigation and timing (PNT) solutions for aerospace, defense, space and various other critical infrastructure markets.

Terms of the deal were not disclosed. Orolia has more than 435 employees in Europe and North America and annual sales of about $102 million.

Safran said the acquisition is meant to help it become a world leader in resilient PNT.

“The acquisition of Orolia makes Safran one of the only companies with the full complement of PNT technologies, bringing together Orolia’s precise time referencing and Safran Electronics & Defense’s proven inertial navigation solutions,” Marin Sion, CEO of Safran Electronics & Defense, said in a statement. “Our shared ambition is to become the world leader in resilient PNT for all conventional and strategic applications.”

Orolia’s products include atomic clocks and oscillators, emergency locator transmitters and beacons, network time servers, and a testing and simulation platform. The company also provides expertise in interference detection and mitigation.
