Recent Study on the Criticality of Space Based Oscillators for the Optimal Performance of Time-Based Signals

Abstract

The oscillators, which are essential for precise timing, are at the heart of a satellite-based navigation system. The purpose of this research is to investigate the crucial role that space-borne oscillators play in increasing the performance of GNSS and satellite-based augmentation systems (SBAS). The African contribution to the SBAS, the NIGCOMSAT-1R navigation payload, which uses externalised 10 MHz Master Oscillators in a 3 X 4 hybrid array configuration, examines the efficacy of Location Based Services using Navigation for Emergency and Crisis Management, among other applications.
