Researchers at Dublin City University have successfully tested laser components contained within the next generation of atomic clocks for space navigation.
Working with Eblana Photonics and Enlightra, the DCU team demonstrated for the first time a new calibre of laser which will allow more efficient and compact implementation of atomic clocks for future satellite missions.Space navigation systems are reliant on this hyper-accurate timekeeping with an error of just a nanosecond potentially leading to distance and positional problems.
The laser is smaller and requires less power than previous iterations, which is vital for use on board satellites.
