Ground Control, a specialist in resilient IoT connectivity, has launched a compact, low-power, dual-mode remote telemetry unit built to serve critical infrastructure operators with widely dispersed assets. The RockBLOCK RTU Micrologger is a dual-mode RTU for reliable remote monitoring for environmental and utility operators.

It is particularly designed for use by water utilities and environmental monitoring teams needing to collect small but important data points. Typical use-cases might be remote measuring of tank levels, flow rates, or pressure, on a daily or event-driven basis from sites well beyond the reach of terrestrial or LoRaWAN networks.

The device captures and transmits sensor data via Iridium SBD, NTN NB-IoT, or cellular. It is designed to offer a seamless, low-cost way to retrieve critical information from even the most hard-to-reach locations.

Key features include:

• Dual-mode connectivity: Iridium SBD + NTN NB-IoT for global, always-on coverage
• Ultra-low power consumption: Ideal for solar or battery-powered deployments
• Sensor compatibility: Supports analog and digital sensor inputs
• Compact and rugged: Built for tough field conditions with minimal installation overhead

Pilot projects are currently underway in the UK and North America, with the dual-mode Iridium/cellular version available now and the NTN NB-IoT enabled devices ready for customer testing at the end of September.

Alastair MacLeod, CEO at Ground Control, said: “You don’t need a complex system just to collect a couple of sensor readings a day. You need something simple, reliable, and built for the real world. That’s what the RockBLOCK RTU delivers.”
