Low-cost clocks for alighting on a Moon

A European time accurate to a trillionth of a second is set to be used on satellites and missions to a Moon.The ultra-precise time-keeper was recognized by a tiny association in Latvia, and ESA has recognized a intensity for space.

Laser to a Moon

“We are a Ferrari of timers with a components of a tractor,” says Nikolai Adamovitch of Eventech.

“We yield impassioned timing correctness regulating arguable and simple electronics. How accurate? They are means to magnitude a time that light takes to transport one centimetre.”

Small and cheap, they turn a rival apparatus for laser-ranging when interconnected with a computer.

More than 50 belligerent stations around a creation already use them to pinpoint a positions of satellites by measuring a round-trip time for a laser beat to strech a aim and return.

The association is already a universe personality in timers for satellite laser stations though is looking to send a record into space.

Radiation-proof and Moon-bound

Each member has during slightest 3 layers of deviation protection. A cloaking renders a device resistant to repairs or malfunctions from vast rays.

ESA has selected a timer to fly to a Moon’s south stick on Russia’s Luna-27 lander in 2022. Neptec UK is teaming adult with Eventech to ready a moody indication for launch.


Neptec are operative on a ‘lidar’ – a laser homogeneous of radar – as an essential partial of ESA’s unconstrained alighting and navigation complement for Luna-27.

The time will magnitude a time light pulses take to lapse to Luna-27 after bouncing off a aspect during landing.

“This allows us to build a 3D map to name a best alighting site, avoiding disproportionate turf and vast rocks,” explains Kerry Sanz, a plan manager during Neptec.

This ‘made in Europe’ record will also advantage us on Earth: “There could be some-more applications for impassioned deviation environments on Earth such as chief energy stations or molecule accelerators such as a Large Hadron Collider,” says Nikolai.

Other uses embody synchronising time between inclination by ocular fibre, deep-space laser communications, and laser altimetry to collect 3D information on Earth’s surface.
