Sensors that operate independently are now essential across countless industries, and users everywhere share the same expectation: these sensors need to work continuously, whatever the circumstances. To keep them reliably connected and functional, strong communication systems are a must. Key needs like worldwide coverage, resilience to tough weather, reliable uptime, and quick connections are best met by adding satellite communications into the mix.
To understand the crucial role that satellite connectivity plays in connecting these sensors, it’s important to first understand what they are and how they are used in the field.
Unattended sensors: why do they matter?
Unattended sensors are the silent backbone of autonomous systems, tirelessly gathering and sending crucial data every hour of every day. Built to endure extreme conditions for years, even decades, without needing human intervention, these sensors are often deployed in far-off areas where cellular networks are unreliable or nonexistent. This reality makes satellite solutions essential, either as a primary link or a reliable backup for maintaining connectivity.
Our partners’ satellite networks are particularly well suited to connecting unattended sensors, as they offer complete global coverage. Each satellite in the network is linked to neighbouring satellites, creating a seamless global coverage network.
Positioned in Low Earth Orbit (LEO), the constellation ensures a fast, low-latency connection, and its L-band frequency guarantees a stable, weather-resistant signal. Together, these features make Iridium an ideal choice for maintaining unattended sensor connectivity in all environments.
Unattended sensors: How do they work?
Unattended sensors in remote areas are integral to the satellite Internet of Things (IoT) landscape. These compact devices are deployed in hard-to-reach environments, either as standalone units or attached to equipment.
Designed for a range of tasks, they can be programmed to monitor specific conditions, issue alerts when thresholds are met, update status, or track ongoing processes. Once collected, this data is relayed regularly to end users, keeping them informed in real-time.
Thanks to high-performance satellite networks, satellite IoT developers can design a variety of sensor solutions to meet all connectivity needs. Solar-powered asset tracking systems support extended deployments, while advanced computing enables sensors to send only essential data, improving profitability and operational efficiency.
With our network of leading satellite technology partners, we can provide you with a broad portfolio of high-performance satellite IoT solutions, designed for low power consumption, energy efficiency, affordability and long deployment cycles. Developers also have extensive resources and connectivity options through IoT terminals and modules or can create new applications using our partners’ core technology for flexible and innovative solutions.
Real-world impact of unattended sensors
Unattended sensors are essential tools for industries worldwide, operating in some of the planet’s harshest and most unpredictable environments. From oil and gas companies tracking pipeline integrity, remote weather stations monitoring severe storms, and railway systems assessing track conditions, to tsunami buoys offering early warnings, these sensors are everywhere, playing a critical role in safeguarding our world.
In agriculture, for instance, unattended sensors are widely used to observe environmental changes over vast, isolated farmlands across Latin America. Conservationists also deploy these devices to monitor ecosystem changes, such as melting ice caps and glaciers, and to track migration patterns of endangered species like the Adélie penguin population in Antarctica, providing valuable insights that contribute to global conservation efforts.
There’s a wealth of information to explore in this domain, and what we’ve highlighted so far is merely scratching the surface. By leveraging satellite communications to link unattended sensors, businesses and organizations from a wide range of industries can efficiently monitor and collect data on nearly any subject, regardless of location.
Unattended sensors are now vital across various industries, and one expectation is common: they must operate continuously, regardless of circumstances. To ensure their reliability, a robust communication system is essential. Key requirements such as global coverage, resilience in extreme weather, high uptime, and fast connections are best fulfilled by integrating satellite communication (SATCOM).
The Role of SATCOM in Connecting Unattended Sensors
To understand the importance of satellite communication in linking these sensors, it’s essential to first understand what unattended sensors are and how they operate in real-world applications.
Unattended Sensors: Why Are They Essential?
Unattended sensors form the backbone of autonomous systems, tirelessly collecting and transmitting crucial data 24/7. These sensors are built to withstand extreme conditions for years, or even decades, without requiring human intervention. They are often deployed in remote areas where cellular networks are either unreliable or unavailable. In such environments, satellite communication becomes indispensable, either as the primary means of communication or as a reliable backup.
Our partners’ satellite networks are designed to offer complete global coverage. Each satellite in the constellation is interconnected with neighboring satellites, creating a seamless global network. Positioned in Low Earth Orbit (LEO), these satellites provide fast, low-latency connections. Their L-band frequency ensures stable, weather-resistant signals, making Iridium an ideal choice for maintaining uninterrupted sensor connectivity in even the harshest environments.
How Unattended Sensors Operate
