Southampton Sailing Robot test logs 2016-2018

<p>These files contain recorded data from the <a href="https://www.sotonsailrobot.org/">Southampton Sailing Robot Team</a>&#39;s boat, the <em>Black Python</em>.<br> The logs cover various test runs, and three <a href="https://www.roboticsailing.org/">WRSC</a> competitions: 2016 (viana), 2017 (horten) and 2018 (calshot).<br> &nbsp;<br> Each test run generated several files:<br> &nbsp;</p> <ul> <li><code>.bag</code> and <code>.bag.metadata</code>: <a href="https://wiki.ros.org/Bags">Rosbag</a> files, recordings of messages sent among parts of the control system, which was built in the ROS 1.x framework. ROS includes tools to inspect and replay these files.</li> <li><code>params-dump-*.jsn</code>: JSON dumps of the parameters used to launch that run,&nbsp;including waypoint GPS coordinates and sensor calibration parameters, among other values.</li> <li><code>gps-trace*.csv</code>: GPS coordinates of the boat during the run, in the format required by WRSC. The three columns are timestamp (`hhmmssdd`), latitude and longitude both converted to integers by multiplying decimal degrees by 1e7, i.e. shifting the decimal point 7 places to the right. All GPS coordinates use the WGS-84 reference.</li> <li><code>gps-raw-nmea*</code>: Raw NMEA-0183 protocol data sent by the GPS receiver. This should be redundant with the CSV data so long as it was parsed correctly.</li> <li><code>map-gps-trace*.html</code>: GPS traces plotted in interactive maps using <a href="https://python-visualization.github.io/folium/">Folium</a>, overlaid on OpenStreetMap tiles.</li> </ul> <p><code>index.html</code> contains a generated overview of the test runs performed, and the files associated with each.<br> &nbsp;<br> The source code used to create these files, including both the control system for the boat and scripts for processing the data is available in a git repository at:<br> <a href="https://github.com/Maritime-Robotics-Student-Society/sailing-robot">https://github.com/Maritime-Robotics-Student-Society/sailing-robot</a><br> &nbsp;<br> Exactly what data is in the different runs varies as the hardware and software were evolving at the same time. We did not record which commit generated each file.</p>
