Hardware and Algorithm Implications of Adding Galileo Capability to an SPS GPS Receiver

摘要

The GPS market needs to move to high sensitivity very rapidly, and then to Gahleo, but the timescales are too short to allow repeated new developments at chip or board level. A new chipset offers first high sensitivity in the same pinout and software API as current volume products, then a year later extends to Galileo. The GPS version is in volume production now. The year's grace allows the new hardware and software required for Galileo to be developed, still two years before the Real constellation is available
