Generate GPS Signals

• Self-generate and supply GPS signal under disturbance of GPS signal
• Continuous monitoring on local input GPS signal – Jamming and Spoofing
• Automatic changeover to self-generated GPS signal when local input GPS signal is disturbed
• Automatic changeover to local input GPS signal when it is recovered
• Generates at least 12 GPS L1 satellite signals
• Generates GPS signals based on standard time and satellite tracking
• Acquires location information from local GPS signals
• Synchronizes precision timing using local GPS signals
• Maintains high precision clock and synchronized to external input standard signal (KRF-E1)
• Maintains synchronized precision timing with remote IEEE1588 PTP Master
