Long-term frequency stability improvement of OCXO using CSAC
2016 European Frequency and Time Forum (EFTF), 2016In this paper we introduce long-term frequency stability improvement of Oven Controlled Crystal Oscillator (OCXO) using Chip Scale Atomic Clock (CSAC). Compared to OCXO, the main disadvantage of the CSAC is their higher phase noise; however the CSAC features with better long-term frequency stability, much lower power consumption and much faster warm-up.

Composite USO/CSAC timekeeping system
2012 IEEE Aerospace Conference, 2012The recent introduction of a first generation of chip scale atomic clocks (CSAC) offers an opportunity to enhance space-based communication and navigation systems with their unique aspects of frequency accuracy and very low size, weight and power. Nonetheless, CSAC frequency noise levels are likely too high to be used directly as master frequency ...

BDS in Challenge Environment Using CSAC
2019 Joint Conference of the IEEE International Frequency Control Symposium and European Frequency and Time Forum (EFTF/IFC), 2019BeiDou Navigation Satellite System (BDS) receiver cannot navigation solution with less than four satellites signal in challenge environment, such as urban canyons or forests. The position accuracy in the vertical direction is frequently challenged in comparison with the one in the horizontal direction.

Space CSAC: From Concept to Qualified Product
The Precise Time and Time Interval Systems and Applications Meeting, 2019Soon after Microchip’s SA.45s Chip Scale Atomic Clock (CSAC) entered production, prospective customers began inquiring about the part’s radiation tolerance. These inquiries resulted in a series of TID tests from 2011 to the present day. It became clear that the standard production CSAC was not a good candidate for LEO applications; the first two CSACs ...

A Study On Ppp Clock Augmentation Using A Csac
2017Precise Point Processing (PPP) is a navigation technique able to provide high precision, at least on the order of few centimetres, based on precise clock and satellite orbit data models. However, the main drawback of PPP is its convergence time, which depends mainly in satellite visibility and geometry, among other factors.
