This is decoder and viewer for the YB race data. YB (https://www.ybtracking.com/) is a commonly used software for tracking boat races. They offer online versions written in JS as well as apps for Android and IOS the follow the races.
This repo contains my own viewer for the data written in JS (see directory "html"), as well as a command line version written in C (see directory "cli"). The latter contains a shell script which lets you download and decode all data into JSON files for your own further processing.
This software is written specifically for the Golden Globe Race 2022 (see
https://goldengloberace.com/live-tracker/) but it should work with any other
race as well. decyb.html is the entry page and you can add the URL parameter
race=... to specifiy a specific race, e.g. race=ogr2023 to show everything
about the Ocean Globe Race 2023.
To use it locally within your browser just clone this repo and then open the
file html/decyb.html and add the URL paramter race=ogr2023 or whatever race
you wanna see.
The C version definitely works since it is just a decoder, the JS version would need some adaptions (see code for details).
The JS code contains the full standalone viewer including the complete projection code for the Spilhaus projection.
