INTRODUCTION<br>
=============================================================================</p>
<p> This dataset contains open-loop data collected by the Planetary Radar<br>
and Radio Science Group at the Jet Propulsion Laboratory from the Low-SNR<br>
Ground System Demonstration with DSS-25 in May 2020. Futhermore, it<br>
also provides the necessary data behind the figures in the corresponding<br>
publication. This dataset is provided in order to supplement the submitted<br>
article to the "Radio Science" journal</p>
<p> Buccino, D.R., et al (2023), Precision of Spacecraft Doppler Tracking <br>
at Low Signal-to-Noise Ratios, Radio Science, submitted<br>

ARCHIVE INFORMATION<br>
=============================================================================</p>
<p> This archive contains several data types, located within subdirectories.<br>
<br>
ROOT<br>
`- 159TEST2022133_1845X25X25RO.A02_XATnn_nndBHz<br>
<br>
These files are the open-loop data collected at the DSN <br>
during the test. There are six files, one for each SNR level. The<br>
files are in the DSN-standard 0159-Science format (binary data).<br>
To decode these files, one should utilize the software <br>
interface specification documents from the Planetary Data System<br>
radio science documentation bundle:</p>

This directory contains all data necessary to reproduce the figures<br>
in the publication. Data include Doppler residuals, SNR measurement,<br>
Allan deviation and associated parameters. Each file in this <br>
directory is plain-text.</p>
