Hi Steve, let me first off say that what your doing is very
impressive;
Likewise - what you guys are doing time-wise is very impressive.
I think the level of precision you guys are aiming for is massive
over-kill for my application. Holding +/- 1 us over 15 minutes would
be a doddle by many means as has been mentioned by you guys. I just
wanted to know whether the basic GPS mouse PPS would stay accurate
enough to do the job for my application.
Radio astronomy is a hobby - i.e., a source of fun - although I do
strive to maintain a level of scientific rigour to the best of my
abilities. One of the key drivers of the fun is doing things with
simple systems. I get extra pleasure in using a $20 DBTV dongle as my
pulsar receiver to achieve the detection of a pulsar glitch (AFAIK the
first time an amateur has ever done so on any pulsar). You can pay up
to $8,000 or so for the best SDRs. Hence, while more sensible/serious
people might go the way of playing with more complex systems I am
motivated to do it with as simple/basic a system as possible. Granted,
this approach does not always work - but when it does it greatly
enhances the fun factor for me.
So - if I don't seem to be following the 'sensible' path you would
probably be right ;-)
BTW - I have just had one of those wacky ideas pop into my head which
has the potential to simplify things for my particular application. I
will evaluate it in the next week or so.
Cheers
Steve
