Small Satellite Position, Navigation, and Timing Innovations Vol. 3 - Two Way Ranging for Time and Frequency Transfer in LEO Constellations

Abstract

This final report documents the work completed by researchers and students in the Colorado Center for Astrodynamics Research (CCAR) and Smead Aerospace Engineering Sciences at the University of Colorado Boulder, to model and develop technologies and algorithms to advance small space platform positioning, navigation, and timing, with a primary emphasis on timing systems. The report is presented in three volumes. Volume 1 presents the CONTACT software defined radio (SDR) based testbed for measurement and ensembling of low size, weight, and power (SWaP) atomic clocks. Volume 2 describes the development of a CSAC flight experiment to be flown on the MAXWELL UNP-9 CubeSat, expected to be launched in 2023. Volume 3 focuses on modeling and analysis of distributed optical time and frequency transfer across small satellites in a large-scale low Earth orbit (LEO) constellation.
