This paper describes the architecture of the real time SensorGrid system, which supports the real-time message routing and processing of Global Positioning System data. The current system processes 1 Hz position data from 85 stations in southern and central California. This system is built on a computer network-enabled, topic-based publish/subscribe system and is extensible to other data sources. In order to determine the performance and the upper limits of scalability, here a set of systematic test evaluations of this implementation is conducted and present. These tests are able to show that performance does not degrade over time, that the system will handle up to 1000 simultaneous data providers or data consumers with a single message broker.
