Basically what I want to do is take a signal from a GPS receiver and discipline the system time on a Solaris machine. However, the GPS receiver I need this to interface with is not listed under the supported drivers page. The receiver I need to use has a RS232 serial port (which I have the complete specs on). Is it possible to write an external reference clock driver that I will be able to use to complete thisproject?The receiver outputs a 1PPS-UTC signal, so would I somehow use the NTP PPS Clock Discipline (Driver 22) to receive that 1PPS signal? Or am I way off?
If you have a PPS signal, preferably connected to the DCD line of a serial port, then you can use the network to achieve rough sync, at which point the PPS signal will kick in to get you down from ms to us level.
OTOH, it is quite likely that you GPS is capable of working in NMEA mode, in which case you can simply use the regular NMEA driver, which automatically uses the PPS signal if available.
