Hi,
Obviously you cannot read a 100Hz display. I assume you have some kind of signal that you want to use to generate a timestamp, like a stopwatch but for absolute time rather than relative. Some timing GPS receivers have a trigger (event capture) input that generates a time stamp. Trimble's Acutime and earlier Palisade units have this feature. The acutime has an event resoultion of about 0.5uS, 20,000 times better than your 1/100 of a second requirement. I have a used Palisade that I could sell you. The manual is here http://www.dc2light.pwp.blueyonder.co.uk/Webpage/PALISADE-Manual.zip
I'm in the UK.
 
Regards,
Robert G8RPI

Subject: [time-nuts] Precisione GPS based led clock






Dear  all
I am an amateur astronomer working in the field of minor planet occultation. 
To arrange a precise reference  time I am looking for a 1/100 sec LED dispaly clock GPS based. (LED is usefull for night vision)
My idea is to use a "ebay" used master clock such as  " ThunderBolt GPS disciplined clock" to drive a timecode display. Particulary I wish to realize a "PIC" based LED clock to display hour min sec and use the 10 MHz reference to arrange an  1/10 and 1/100 sec disaply.  Can anyone help me in finding schemes or any more flexible idea?
thanks
