During a live game, Trackman's system tracks every play — measuring pitch tracing metrics like pitch velocity, spin rate, spin axis, pitch trajectory, exit velocity and ball flight measurements.

This information is collected by the Trackman radar and vision tracking system installed at the stadium. Once the data is captured, ActiveMQ takes the ball measurements and pushes them to MLB in real time so they can be: 

• Stored in their database 
• Merged with MLB’s in-game metadata (instead of our tagged metadata) 
• Distributed afterwards as they see fit

Data flow between Trackman and AMQ

The data flows like this: 

Trackman PTU → Trackman Computer → AMQ → MLB Servers → MLB Database 

AMQ uses a failover connection string, meaning it's configured with two server addresses. If the connection to the first MLB server drops, it automatically switches to the second — minimizing any interruption in data delivery.
