Hi!
In my network I have 2 Meinberg M200 clocks and 4 other GPS receivers (1
Sure GPS Evaluation board, 2 Garmin 18 LVC and a uBlox EVK-6N). I
recorded the GPS timecode strings across 00:00 UTC to see how they would
react to the leap second:

Hi!
Lately I've been using the two stratum 2 servers our national observatory
provides to the public mainly as backup for my GPS based local NTP servers.
I've always found odd that one of them exhibited an erratic behaviour when
compared to the other one.
I decided to use ntpdate on one of my

I don't think there is such a beast. Once you get away from the radio

I've recently bought a Trimble Acutime gold that will be used as a

I'm looking at the Resolution T from Trimble

Does anyone here connected it successfully to a computer?
Are the voltages compatible with RS232 or do I need some converter?
Thanks!
