This is a
gpsd server located in Singapore.
The server runs the master branch of both the gpsd and NTPsec projects, so may frequently be restarting.
It is a member of the
NTP Pool since 2008, and has been available on IPv6 since 2012.
It supports NTS, and you are encouraged to use that, for some additional security.
You should use one of the following lines in your ntpd.conf (in order of preference):
A filled shape means the satellite was used in
the last fix.
Green-yellow-red colors indicate signal to noise ratio in dBHz green=best,
yellow=fair,
and red=worst.
Circles are GPS and QZSS satellites.
Diamonds indicate augmentation (SBAS, WAAS, etc.) satellites.
Triangles pointing up are Galileo satellites.
Triangles pointing down are BeiDou satellites.
Squares are GLONASS satellites.
