There are three supported routes for bringing external data into ATLAS. Which one you pick depends on whether your data is live or historical, where it currently lives, and what language and tooling you're working with.
For decades, getting live engineering telemetry out of a car and into the tools that make sense of it has meant working inside closed, proprietary formats. Open Streaming changes that. It is a broker-based, API-first architecture for moving telemetry in real time over documented standards, so the data is yours to route, store, and build on however you like. This post is an introduction to the idea, why we built it the way we did, and what it can unlock.
This started because I asked our designated sim racer, Oli, if he had any SSN2 files from his runs I could pull into ATLAS and poke at. He did not send me SSN2 files. He sent me a link to the iRacing SDK and down the rabbit hole I went. Three days later, I had a working bridge service that streams live iRacing telemetry into ATLAS through the Stream API.
Modern motorsport is driven as much by data as by drivers and machines. This article explores how information flows from hundreds of sensors on a Formula 1 car, through onboard systems and telemetry links, and ultimately into the hands of engineers making critical decisions in real time and over an entire season.
