Details
Orolia group company, SpectraTime today confirms its position as a strategic supplier in the market for atomic clocks on board and as the world leader in technologies clocks to satellite navigation. Less than a month after winning a program in the amount of 2.5 million euros for the development of critical technologies for a future space active maser, the company has indeed won a contract amount of approximately 0.5 million of ESA. It covers the design and implementation of a passive hydrogen maser space next generation. This work aims to reduce by one quarter, without loss of performance, size, weight of the hydrogen maser liabilities of the European Galileo satellite positioning, which are the atomic clocks space as accurate in the world.
The technologies that will be developed under this new contract will allow passive hydrogen masers come directly compete cesium clocks, offering size and weight equivalent superior performance for navigation systems for future generations, such as GPS III, Glonass and Galileo Evolution. They also serve as the basis for the development of new products soil. Recall that it was the success of in-orbit testing of all key components of Giove-B, the second experimental satellite of the Galileo system launched in April 2008, which helped dedicate the passive hydrogen masers as the atomic clock technology the most promising for satellite navigation.
"Our technology maser has already demonstrated a capacity for stability of the reference time of the navigation system of a few fractions of a billionth of a second. Subject to master the phenomena of signal propagation through the atmosphere and errors model orbital satellites, such a performance paves the way for a positioning accuracy of 10 centimeters on the ground, and many new applications, "says Pascal Rochat, CEO SpectraTime.
The development of this new "mini-maser" hydrogen liabilities will be carried out in collaboration with the Italian company Galileo Avionica, acting as prime contractor. For its part, SpectraTime develop the heart of the clock, linked to the preparation of hydrogen atoms in appropriate physical condition and "reading" miicro-wave resonance frequency ultra-precise, originally exceptional performance of the atomic clock.
