Hi,
I recently bought 2 ublox PCI-5S mini-PCI GPS modules and have ordered a
PCengines APU2C4 board I hope to install it in.
Others have found it can provide PPS output

The NVS NV08C GPS receiver module is a rather nice little 32 channel
GPS/GLONASS/SBAS receiver that has an output message that gives you the raw
satellite bit streams. They can be had for around $60 bare module ($120 on a
breakout board from sylphase.com). They also support carrier phase inf

Oh, good! So Eagle may become even harder to learn and use! ;-)

This board just seems to be the RF front end for a GNSS receiver. You then
have to do the whole business of acquiring and tracking the code, and then
do the PVT solution, at which point you can make your own 1 PPS.

I'll throw Designs Park into the mix, it's a free program from RS
components and I *think* it generates gerber files.
I've used it for a couple of boards and got a grasp of it on a quiet
afternoon.

A shame, it looks like it can be externally clocked, but I don't see a
way to get in and measure a PPS signal.

I've been studying machine vision for years and now finally the prices are

3D models of the environment and I think humans use many of these.

For me, the ideal solution is an eyeglass-mounted surgical loupe such as

Hi Guillermo!
Nice to see you ask questions here!

If you have to regulate over ambient temperature as high as 120C, you need
an oven that regulates at a higher temperature, maybe 125 at least or 130C.
You will have a lot of issues with long term reliability with something
that operates 24/7 above 120C.
