u-blox wireless semiconductors and modules

u-blox is a global technology leader in positioning and wireless communication components. Founded in 1997 as a spin-off from the Swiss Federal Institute of Technology (ETH) in Zurich, the company established itself as a pioneer in miniaturized GNSS (Global Navigation Satellite System) receivers and cellular IoT modules. The brand serves automotive, industrial, and consumer markets, providing the hardware and software that allow devices to determine their precise location and communicate wirelessly.

While headquartered in Switzerland, u-blox operates as a fabless semiconductor company, meaning it designs its products in-house but outsources the actual fabrication to major semiconductor foundries worldwide, including locations in Taiwan and other parts of Asia. In late 2025, the company underwent a significant ownership change when the global private equity firm Advent International completed a $1.3 billion acquisition to take the company private, marking a new chapter in its corporate governance while maintaining its focus on IoT and high-precision positioning services.
