Overview

The backend sends telemetry data to the frontend in real-time as it receives information from the rocket using the RN2483 radio. Alternatively, we can replay past flown missions that have been recorded.

This is exclusively controlled by the React frontend. This is done using industry standard web sockets and all data is sent in JSON format for ease of use. See websocket.json for an example of data transmission. Numerous clients can connect to the WebSocket and obtain telemetry information from the rocket.

See the Development Quick Start to learn how to get the backend up and running.

Here are some reference documents for the radio module we are using:

• Reference manual
• Data sheet

The radio packet format that we decode in this application is described in this spec.
