The Architecture of Modern GPS Tracking
Understand how GPS data moves from tracker packets and protocols through ingestion, processing, storage, events, realtime systems, automation, APIs, and fleet applications.
About This Guide
The Architecture of Modern GPS Tracking explains how a modern vehicle tracking platform works from the moment a GPS tracker generates a packet to the moment an operator sees information on a live map and acts on it.
The guide introduces the 10-Layer Modern GPS Tracking Architecture and follows data through sensing, device logic, connectivity, protocols, ingestion, normalization, processing, time-series storage, events, automation, APIs, realtime distribution, and user applications.
It explains GPS protocols, TCP and UDP, listeners and decoders, current state versus historical telemetry, time-series and spatial data, Redis, queues and workers, stateful event processing, workflow automation, device commands, REST and realtime APIs, web and mobile applications, reporting, authorization, scaling, reliability, and observability.
Open VTS is used as a concrete architecture reference where appropriate while keeping the majority of the guide applicable to the broader GPS tracking category.
