    In-House Production and R&D

    At Geolux, our entire production process takes place under one roof, ensuring complete control over quality and performance. Each stage of production, from concept to final assembly, can be assessed, tested, and calibrated on the spot. This integrated approach allows us to maintain smooth workflows and consistently meet project deadlines.

    Unlike many suppliers who rely on third-party components, Geolux’s success is driven by our powerful in-house R&D team and the development of every critical part. Our in-house capabilities include the design and production of microwave circuits and antennas, signal processing electronics, communication interfaces, embedded software, configurator applications, and mechanical components.
    This vertical integration gives us the flexibility to respond quickly to market changes and customer needs, ensuring that every Geolux product reflects the highest standards of reliability, innovation, and precision.
