[SLUG] GPS as a time source

2001-11-27 Thread Matt Hyne


I have a GPS received that I would like to try and use as a time source for NTP.  It 
is a Magellan GPS with a serial data interface.

Anyone know if there is any linux software support to use a (this) GPS as a time 
source for an NTP box ?

The type 20 driver takes standard NMEA data... but will be inaccurate due to serial 
interface jitter.

You need a GPS that puts out a one pulse per second (PPS). See 
http://www.tapr.org/tapr/html/Ftac2.html and related pages for some good interface 
hardware.
