What Are LEO Satellites and How They Work
LEO (Low Earth Orbit) satellites are satellites that operate in low orbit around Earth, generally at altitudes from hundreds to around two thousand kilometers above the surface. This position closer to Earth enables LEO satellites to send and receive data with lower delay (latency) than conventional satellites in higher orbits. Because of that, LEO satellites are an ideal choice for fast and responsive data communication needs.
The way LEO satellites work involves a network or constellation of interconnected satellites moving around Earth. Devices on the surface, such as IoT sensors or user terminals, connect to the nearest satellite passing above them. Data is then forwarded between satellites or directly to ground stations before being sent to a central system. This mechanism enables more even connectivity, including in remote areas, and supports real-time data exchange in the IoT ecosystem.
Differences Between LEO Satellites and Conventional Satellites
The difference between LEO satellites and conventional satellites is easiest to see from their distance to Earth. LEO satellites are closer, so data transmission can happen faster. Meanwhile, conventional satellites are much higher, which makes response times tend to be longer.
In how they work, conventional satellites usually rely on a smaller number of satellites. In contrast, LEO satellites work in a network of many interconnected satellites. This pattern makes connections more even and stable, especially for areas that are difficult to reach. That is why LEO satellites are more suitable for supporting IoT needs that require fast and continuously active connections.
Use of LEO Satellites for IoT in Various Sectors
LEO satellites are widely used to support IoT in various sectors because they can provide broad and stable connectivity. In the industrial and mining sectors, LEO satellites are used to monitor equipment, environmental conditions, and field operations in real time, even in remote locations. Data from IoT sensors can be sent directly to help faster and more accurate decision-making.
In the transportation and logistics sector, LEO satellites support tracking vehicles, ships, and moving assets without depending on terrestrial networks. Meanwhile, in the agriculture sector, this technology is used for monitoring land, weather, and sensor-based irrigation systems. With broad coverage and fast response, LEO satellites allow IoT to be applied more effectively in various fields, including energy, healthcare, and public services.
In practice, the use of LEO satellites for IoT is also becoming stronger with the presence of Starlink. As an LEO satellite-based internet service, Starlink provides stable, low-latency connectivity, making it suitable to support continuous IoT data transmission. Sensors, monitoring devices, and automated systems can connect to the network without having to depend on terrestrial infrastructure.
With Starlink support, IoT implementation can be carried out in various sectors and locations, including remote areas, the sea, and temporary operational areas. Data from IoT devices can be sent to central systems or analytics platforms in real time, helping companies improve efficiency, safety, and decision-making speed. This makes Starlink one of the important supporters in the development of the LEO satellite-based IoT ecosystem.
Challenges and Opportunities in Developing LEO Satellite-Based IoT
The development of LEO satellite-based IoT still faces several challenges. One of them is the relatively higher initial cost of devices and services compared to conventional networks. In addition, complex satellite network management and the need for integration with terrestrial systems and data platforms are also challenges, especially for organizations that are just starting to adopt IoT.
However, behind these challenges, the opportunities offered are very large. LEO satellites open IoT connectivity access to areas that were previously difficult to reach, such as remote regions, open seas, and special operational areas. With lower latency and broad coverage, LEO satellite-based IoT enables real-time monitoring, automation, and data collection across various sectors. In the future, technological development and increasingly large usage scale are expected to make this solution more efficient, affordable, and an important part of the global IoT ecosystem.
