2 Product Overview
The Swarm Tracker satellite data modem transmits and receives data to and from Swarm’s
space network and is designed as a standalone product. Swarm backend systems can support
the delivery of customer data via a REST API to the cloud service of each user’s choice.
The Tracker is a ruggedized device suitable for a variety of low-bandwidth use cases: from
connecting people and tracking vehicles, ships, or other assets to relaying sensor data for
agriculture, energy, and industrial Internet of Things (IoT) applications.
Using proven IoT technologies, the Tracker is easy to use on its own or with a third party device
requiring connectivity. The Tracker communicates via a standard USB-C serial cable, over
Bluetooth, or via WiFi.
