After a couple off-the-list emails with Bob, if anyone else wonders as well: just send me a direct email. I'm about the only one that can get you a license :-)

Anyone interested can reach out to me.

Roel.

Hi

Since you brought it up …. :) :)

Just how in the world do you get an Atomicron subscription? I’ve asked about this a number of times.
I have never been able to get a “click here” sort of answer.

Hi Time Nuts,

I'm Sean and I work at SparkFun Electronics. Historically, my company
has made dev boards and primarily been in the embedded space, but our
founder has recently gotten really into the world of high-precision
GNSS, which has also led us into the wacky world of timing.

I'm not really here to sell you anything (but don't let that stop you,
hah) but more curious what your thoughts are on a new product we just
came out with (https://www.sparkfun.com/sparkpnt-gnss-disciplined-oscillator.html).
Without the Atomichron subscription ($1k/month), it can get accuracy
around 5ns. With the subscription, it gets to within 100 ps. It uses
the mosaic-T from Septentrio which has anti jamming and spoofing capabilities as well.
On the product page you can find links to the documentation for the
product, as well as the oscillator and GNSS module inside.

We're curious what your thoughts are on the product. Namely, is this a
good accuracy/price ratio compared to the methods you can DIY? Also,
what applications might you be using sub-nano accuracy for? We aren't
really sure how people will use this product, we just thought it would
be cool to make (while I'm on the subject, are there any features you
would want/expect at this price point that we aren't offering?). Also,
what are your thoughts on Atomichron's subscription service?

Looking forward to having a discussion about this technology with you all.
I really appreciate niche communities like this!

Happy hacking,
Sean
