Galileo signal update aims to boost Internet-of-Things connectivity

The Galileo satellite navigation system has updated its signals to better support Internet-of-Things (IoT) devices, according to the European Space Agency (ESA). The enhancement, announced in a June 2023 press release, focuses on improving signal accuracy and reliability for low-power, wide-area networks (LPWANs), which are critical for IoT applications like smart agriculture and industrial monitoring.
Technical enhancements for IoT compatibility
The update introduces modifications to Galileo’s E1 and E5 signals, enabling them to work more efficiently with LPWAN protocols. These changes allow devices to consume less energy while maintaining stable connections, a key requirement for IoT networks that often rely on battery-powered sensors. The European Commission, which oversees the Galileo program, confirmed the adjustments align with the EU’s broader goals to strengthen global satellite infrastructure for emerging technologies.
Implications for IoT development

The revised signals could reduce latency and improve data transmission rates for IoT devices, according to a 2023 report by the European GNSS Agency (GSA). This is particularly significant for applications requiring real-time monitoring, such as smart city infrastructure and autonomous vehicle systems. “The update positions Galileo as a competitive alternative to GPS and BeiDou for IoT developers seeking robust, low-cost solutions,” said Dr. Lena Müller, a satellite technology expert at the University of Munich.
Challenges and future outlook
Despite the advancements, widespread adoption may face hurdles. Many IoT manufacturers currently prioritize GPS-compatible hardware, and transitioning to Galileo would require updates to existing systems. Additionally, the ESA noted that the new signals are still undergoing field testing in select EU regions. A 2023 survey by the European Telecommunications Standards Institute (ETSI) found that 68% of IoT developers remain hesitant to shift from established satellite systems.
The Galileo update reflects a broader trend of satellite networks adapting to the demands of connected technologies. As IoT growth accelerates, the system’s ability to scale and integrate with global standards will determine its long-term impact.
