Oh well, full credit to Mr Trimble for getting it right, he does bake
exceedingly nice GPS modules and the Ace3 doesn't have a rollover issue and it
does report the date correctly.
Unfortunately, as far as I can tell anyway, the BC637PCI takes the raw GPS
time data from the Ace3 and perform

Hello,
I'll be glad to check my GPS module to see what is going on there,
however I am still waiting for the GPS antenna to be delivered. I tried
to use some small form factor Trimple GPS antenna with BC637, but
on-board GPS module couldn't lock with it. So, my BC637 is working in
"freerun"

It may be that your onboard batteries are in better health than mine are,
although mine might have been disabled using the software, as I tried
booting up without an antenna this evening and got the right year this time
but

That's the document I was refering to when I said earlier that I'd seen
written confirmation from Trimble that they weren't expecting any rollover
problems with the Ace3, I didn't mention the "through the year 2015" comment
as we haven't actually got there yet:-)
That may indeed be an issue
Ah, I took 1999 as I thought that was the only relevant date for another
1024 weeks, I'm not familiar with the shifted 1024 week period so will take a
look at that.
Does "shifted" imply a shift at the whim of the manufacturer, ie could it
explain why these boards might have been ok a few ye

I figured out why GPS FW information was not available by request. To do
such requests BC637PCI needs to be in "GPS MODE". If I run the request
in "Free Run", it return the error code. Here is FW infomation from my
GPS module:

Ah, sorry, when you commented before about modifying the demo software it
obviously didn't register with me quite what you were trying to do.
In the BC637PCI Demo software, I'm using version 7.0.0, under the "Help"
menu, one item is Receiver Firmware Version and this returns the Packet 45

Sorry for confusing information. I have some small Trimble antenna which
currently connected to BC637PCI. However I never get it "locked" with
that antenna:

Ah, now I understand:-)
All I'm using at the moment though is a small Trimble patch mounted indoors
and although it does drop out occasionally most of the time it's ok, have
you checked your satellite signal levels as reported by the BC637 software?
Although my own interest is really only i
You are right ! Now I am going to modify the code a lit bit.
Each time as we call bcReadBinTimeEx or bcReadBinTime, we need to add
"magic number" to unsigned long pointer which store major time. Example:
if (bcReadBinTime(stfp_handle, &btm[1], &btm[0], &stat ) == 0) {
You've lost me, what code are you modifying at the moment, is it the
actual Datum demo software?

I modified two things for now. Its a "demo" software (Linux edition).
And refclock_banncom driver for NTP. Personally, I would prefer to
modify microcode or library. But that is proprietary with no source code
around.
