What is the accuracy variation of the 10 kHz and
1 PPS outputs of the Jupiter-T GPS receiver between
3-D Navigation, 2-D Navigation and 0-D Position Hold
modes, after a couple of hours of reception? Is it
less than an order of magnitude? By default I
understand the Jupiter to automatically sele
Hi David:
Yes, I like it.
Should Increment and Decrement work on the whole counter? for example
when changing minutes you can only increment or decrement the minutes
digit and the 10 minute digit follows?
Thanks & Have Fun,
Brooke

Magnus,
Congratulations. You have moved closer to the goal that motivates
us all, knowing the exact time to 10E-6 times less than human
wetware is capable of comprehending, or is that 10E-12.
It is remarkable that we are able to measure time to far more
precision than we can measure physical thin
Hi:
I've been working on making a LCD based clock where the PIC
microcontroller uses a precision frequency source as it's heartbeat.
Today I got the LCD navigation and time-date setting to work, but don't
like it. The current version stops the clock and then uses the cursor
and blink hardwar

Fellow time-nuts,
This evening I was presented with a dilemma, either to check if my repaired Cs
beam would lockup or go out dancing (and chasing chicks). Being told about the
dancing a bit late, being inproperly dressed, unshaved and all, I felt the
time nut in me was having a strong case, so it
the 1 sec pulse can be used on a counter for a gating the 10mhz on the
counter to set it very close as one example.

That 1 PPS signal ticks on the UTC second boundary. That lets you transfer
accurate time as well as frequency to other boxes.
Suppose you want to build a time server. If you connect up the serial port,
It's often useful to run a local NTP server from 1 PPS, rather than
relying on other machines on the net to give you the time.

Hi All:
I'm an electronics hobbiest, though not necessarily
chronotonically obsessed. I have an Hp-Z3801A GPS receiver
Timebase. I got it to provide an accurate external
10 Mhz reference clock for some HP test gear that I have.
It also has a 1 pulse per second output; what is it good
