Real-time re-transmission of military gps signals as legacy signals
The granted patent (Publication Number: US11988756B2) describes an apparatus comprising a Global Positioning System (GPS) receiver, an oscillator, and a GPS simulator. The GPS receiver is designed to receive L1 or L2 GPS signals, generate timing and position signals, and provide them to the GPS simulator. The oscillator generates a second timing signal provided to the GPS simulator. The GPS simulator generates simulated GPS signals based on the received signals or the oscillator's timing signal, ensuring continuous operation even when GPS signals are unavailable.
Furthermore, the apparatus includes features such as a power manager generating a simulated antenna load compatible with legacy GNSS systems, high-stability oscillators for signal generation in the absence of GPS signals, and compatibility with various GNSS systems like GPS, Glonass, BeiDou, QZSS, or Galileo. The method outlined in the patent involves the same components and processes, emphasizing the generation of simulated GPS signals based on received or internally generated timing signals. This innovation ensures uninterrupted operation and compatibility with legacy systems, enhancing the reliability and functionality of GPS-based applications across different environments and scenarios.
