Corresponding Dataset for Precision of Spacecraft Doppler Tracking at Low Signal-to-Noise Ratios

Corresponding Dataset for Precision of Spacecraft Doppler Tracking at Low Signal-to-Noise Ratios README FILE Dustin Buccino January 1, 2023 Jet Propulsion Laboratory California Institute of Technology ============================================================================= INTRODUCTION ============================================================================= This dataset contains open-loop data collected by the Planetary Radar and Radio Science Group at the Jet Propulsion Laboratory from the Low-SNR Ground System Demonstration with DSS-25 in May 2020. Futhermore, it also provides the necessary data behind the figures in the corresponding publication. This dataset is provided in order to supplement the submitted article to the "Radio Science" journal Buccino, D.R., et al (2023), Precision of Spacecraft Doppler Tracking at Low Signal-to-Noise Ratios, Radio Science, submitted January 2023. ============================================================================= ARCHIVE INFORMATION ============================================================================= This archive contains several data types, located within subdirectories. ROOT `- 159TEST2022133_1845X25X25RO.A02_XATnn_nndBHz These files are the open-loop data collected at the DSN during the test. There are six files, one for each SNR level. The files are in the DSN-standard 0159-Science format (binary data). To decode these files, one should utilize the software interface specification documents from the Planetary Data System radio science documentation bundle: https://pds-geosciences.wustl.edu/ radiosciencedocs/urn-nasa-pds-radiosci_documentation/ `- figures.zip This directory contains all data necessary to reproduce the figures in the publication. Data include Doppler residuals, SNR measurement, Allan deviation and associated parameters. Each file in this directory is plain-text. ============================================================================= ACKNOWLEDGMENTS ============================================================================= This work was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under contract with the National Aeronautics and Space Administration.
