Three major components wirelessly transmit, using the same protocol (ESP-NOW), information allowing for the replay of a training session afterwards and the study of options taken in relation to other boats or according to the wind:
Autonomous GPS buoys broadcast their positioning every second.
One or more anemometers transmit the wind force over the body of water.
The boats' GPS systems also broadcast their positioning every second.
This data can be viewed in real time on the display below and is also recorded on the display's SD card.
Upon returning from training, simply take the "YYYY-MM-DD_HH-MM-SS.json" file from the SD card to replay the data onto a card.
First option, requiring the installation and development of a specific solution:
The video below shows the result with specific software (Node Red), requiring specific development.
A second, simpler option is to use the free Kepler software: https://kepler.gl
The file format on the SD card is in a format that can be read directly by the Kepler software.
The video below shows how to import and replay data with Kepler.
