Cloud-based GNSS corrections services for easy scalability

PointPerfect is delivered via the enterprise-grade Thingstream cloud platform, providing an intuitive experience with powerful features including fleet management, event monitoring and a comprehensive API.

Thingstream also utilizes auto-scaling technology, supporting billions of messages and making it easy to deploy large fleets of UAVs and robotic vehicles.

The service utilizes the industry-driven SPARTN open data format, allowing it to be platform-agnostic and enabling compatibility with a wide range of devices. Messages are sent using the lightweight, scalable, and easy-to-integrate MQTT protocol, conserving bandwidth and driving down data costs.

We offer PointPerfect as a traditional subscription services as well as via flexible pay-as-you-go service plans that allow you to scale up as your business and products grow.
