Marotta UK Ltd is pleased to announce that it has designed, developed and qualified equipment for the cold gas propulsion systems on board the Galileo GIOVE-A, part of Europe’s Galileo navigation program, successfully launched by Surrey Satellite Technology, Ltd (SSTL).
The launch of the Galileo GIOVE-A, the first in a constellation of 30 satellites, marks Europe’s maiden entry into civilian-owned global positioning systems. The complete Galileo constellation (27 operational and 3 active spares) will deliver real-time positioning accuracy down to one meter. By placing the satellites in orbit at a greater inclination to the equatorial plane than current global positioning systems, Galileo will achieve better coverage at high altitudes, which makes it suitable for use over northern Europe, an area presently not well covered by GPS.
With a lead time of only four months, Marotta worked in close collaboration with SSTL to improve performance of and re-qualify its heritage DMC flight-qualified hardware, and contributed to the success of the platform build program with on-time delivery of propulsion system equipment series redundant, specialty valves controlling the flow of gas to the thrusters, as well as high-performance valves for propellant loading during launch preparation.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...
Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
