Orbcomm ST2100


ST2100 delivers dependable, almost global coverage, a compact and rugged design, low power consumption, and flexible I/O interfaces. Ideal for low latency satellite IoT data transmission in remote and harsh environments, with advanced security features and cost-effective operation.


Compact, Rugged and Reliable

Utilizing the virtually global Inmarsat satellite network (only the polar regions lack coverage), the ST-2100 ensures reliable communication from remote and isolated operations where terrestrial networks are unavailable.

Engineered for durability, ST 2100 features a compact and rugged design, capable of withstanding harsh environmental conditions. This makes it suitable for deployment in extreme industrial, maritime, and outdoor settings.

The terminal is optimized for low power usage, which is crucial for applications where power resources are limited, such as remote monitoring stations or solar-powered installations.


Quick and Easy Integration with your IoT Gateway

The ST 2100 features a simplified design for cost-effective satellite messaging. Unlike its sister device, the ST 6100, it can’t be programmed, and instead uses an intuitive AT Command set, enabling quick and easy integration with external PLCs and general-purpose controllers. The ST 2100 can be installed with cable access from either the side or the bottom.

Like the ST 6100, the ST 2100 has built-in GNSS, which provides precise time and location references. It’s suitable for installation on various mobile assets, including light and heavy-duty commercial vehicles, railroad cars, and heavy machinery. Highly versatile, it also works well for remote monitoring and control of fixed assets in industrial and utility settings, such as pipelines, pumps, generators, and tanks.
