Hi Askar,

    You can interface Sirf star II GSP receiver using NMEA ref.clock driver.
    The receiver should support NMEA with GPRMC, GPGGA or GPGLL sentences.

    For PPS support you need to have Linux kernel with PPS patch (Nano
Kernel).
    Or else you need to have FreeBSD compiled with PPS option.

    The configuration is quite simple. You may refer to the following NTP
documents
    http://www.cis.udel.edu/~mills/ntp/html/refclock.html
    http://www.cis.udel.edu/~mills/ntp/html/drivers/driver20.html

    Can you give details of NMEA sentences supported by Sirf GPS receiver.

    Venu
