I would like to configure a debian NTP server using an USB GPS adaptor.

Who can suggest some compatible models (GPS adaptors) for linux?? Anyone have sucesfully configured such an ntp server? Any configuration guide?

Thank you

Are you looking for information on how to configure the Debian server to use the GPS adaptor to register its location?

How do you think the GPS adaptor will alter the NTP server?
Do you want to configure the server to alter the local time setting based on the data it gets from the GPS adaptor?

Just to be clear the NTP server issues the time along with the time zone to the clients that synchronize against it. The client adjusts the time to match its own i.e. if the NTP reports the Time in UTC but the ntp client is in europe GMT+3,
The client adjusts the reported time from the NTP server by adding the additional 3 hours and then checking whether its time is within the threshold of the calculated NTP server time.  If it is, the clock is adjusted if the NTP time is outside the threshold, the client records an error through syslog.

Why not setup a NTP Server and configure it to synchronize against publicly available NTP servers?

Below you might find useful example with a Garmin GPS receiver and Debian patch.
