Compact and low power consumption atomic clocks, also known as CSAC (Chip-Scale Atomic Clocks) have grown a progressive interest during the last decades. Such devices feature the unique capability of a stable frequency and timing reference over extended periods of time, otherwise unreachable with conventional oscillator technology based on quartz crystal or MEMS resonators. Their benefits were…Subcontractors

Start date: 27/02/2020Duration: 15 MonthsGPS has been used in space for more than 20 years and currently it is consistently used in LEO orbit satellites in order to provide position, velocity and time information. Extension of its use to higher altitude missions has been the subject of multiple studies, GEO and GTO orbits currently exploit GNSS signals and the NASA Magnetospheric Multiscale (MMS) mission has recently demonstrated that…Prime contractor

The aim of this activity is to develop the EM of a multi-constellation multi-frequency spaceborne receiver product (called NAVILEO) that addresses the requirements of the New Space market, bringing the gap between today’s low-end and high-end GNSS space receiver solutions, and offering a high performance, autonomous, state-of-the-art navigation solution at an affordable price for single… -
To address higher requirements from customers, Saphyrion has developed, through an internal project the SY1007A and SY1017A devices, which consist of an RF front-end and an AD/DA-converter ASIC for GNSS applications. The SY1007A is a radiation hardened L-band RF down-converter for GNSS receivers aimed at the professional and space markets. It includes all functional blocks needed to implement the… -
GNSS is the only global, free, comprehensive technology providing absolute PNT data to users worldwide. Its limitations are known, including long life cycle and replenishment schedule, affecting their ability to adapt easily to short-term market needs and to some extent, resilience. Considering the above, alternative PNT methods and solutions have been developed or are being investigated,…Prime contractor

Start date: 15/01/2018Duration: 18 MonthsGNSS antennas in user receiver devices are relatively simple. More sophisticated antennas could be designed to bring spatial diversity and gain, and to be more resistant against spoofing and meaconing, as well as reducing other sources of interference, for instance by nulling the gain of the antenna in this direction. Using arrays of dynamic elements (phase/gain controlled) would also make it…Prime contractor
