It is possible to externally assemble the
engine GPS if needed (example Banzi
Lecce)
10Mhz disciplined clock with PPS
Continuos clock also without PPS signal
Multi-GNSS (GPS, GLONASS, Beidou
& Galileo ready)
PPS pulse synchronized to within 15
nanoseconds
(one
sigma)
of
GNSS/UTC

Past & Future
PAST :
• Old system Investigation (back compatibility with old system)
• Desing of new GPS board (GPS and time stamp)
• Investigation about best FPGA model
• Design of trigger and GPS interfaces
FUTURE :
• Upload trigger and GPS interface firmware and test (~ 1 month )
• Practical verification on MRPCs Bologna (~ start end of march)
• Test with DAQ @ CERN (~ start end of april )
