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.

Researchers create new technique for manipulating polarization of terahertz radiation

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
