    Aeronautical systems

    In the aeronautics industry, electronic systems must perform safely and predictably, with strict requirements for reliability and certification. Avionic platforms depend on dedicated computing and control systems, each with specific technical constraints that strongly influence ASIC architecture and design.

    Presto Engineering supports aircraft manufacturers and equipment suppliers by defining and delivering custom silicon solutions engineered for certified avionics systems.

    Satellite communications systems

    In the aerospace and satellite industry, the terms GEO and LEO refer to different types of Earth orbits, each with specific technical constraints and system requirements that directly impact ASIC design.

    Satellite ground stations are the Earth-based infrastructure that enables communication, control, and data exchange between satellites and the ground. They are essential for GEO and LEO missions, as well as for new space constellations. These systems must operate continuously, reliably, and securely while managing increasing data rates, high-frequency RF communications in Ku- and Ka-bands, and complex mission requirements.

    Presto Engineering helps customers navigate the trade-offs between GEO, LEO, RF-intensive payloads, and ground segment architectures to define the most effective ASIC solution for their mission.
