I assume you are taking video of the occultation and want to time tag each frame? If so then there is a better way. All current video standard allow a place in the video stream for time tags. This works much the same way as with still cameras that recordthe date in the image files. You would need a camera that was an input from the time code data.
The other way it is done some times is to put something like IRIG on the audio track. This can be microsecond level accuracy. One more idea... If all you need is 1/100th second accuracy and you have a computer near by then let that computer run and NTP server using a GPS is the reference clock. Even an un-sophisticated NTP setup can run at the millisecond level, ten times better than your requirement. Now that the computer's clock is good any kind of time code canbe generated in software 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. > > Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
