Defence and space technology company Electro Optic Systems (ASX:EOS) leads the ASX tech sector today, after rising 4.81% off the back of its June quarterly.

The company’s space systems division demonstrated a major breakthrough in laser technology which significantly advances the global effort to mitigate space debris.

It’s no sharks with lasers, but it’s pretty cool.

Basically, it uses a guide star laser to allow high speed adaptive optics to form laser beams that can track and move space debris at lower altitudes and faster speeds than previously possible.

The IP was developed in collaboration with the Space Environment Research Centre (SERC), and will now be commercialised (and owned by EOS), with applications including space debris mitigation and high-bandwidth satellite communications.

Plus the space systems team were winners for the second year in a row for the group award Space Business of the Year (Large) in the 2021 Space Connect, Australian Space Awards held on 4 June 2021.

And the company’s defence systems division received a tidy $30 million payment from a customer on a major overseas contract, and signed a cooperation agreement with German-based Diehl Defence focusing on advanced stabilised and remotely operated weapon systems (RWS) for the European and NATO markets.

Oh and the company advanced its SpaceLink ‘communications superhighway for the new space economy’ and is in the process of selecting a satellite manufacturer for building the first constellation of four satellites – and expects to award a contract in Q3.
