That's been taken care of here. Thanks for reviving it though.

Launched last week. It will probably be a couple of months before it gets added to the active constellation of GPS birds.

And last week we said goodbye to the last of the Block II-A (launched in 1990!) birds. Exceed its projected operational life by quite a few years.

In another few years we'll have more civilian frequencies (and receivers that can use them) for better (sub-meter) position accuracy.

The precision time and frequency folks will get added accuracy as well with the added civilian frequencies. With today's systems, I have time and frequency references (at home) that are accurate to 1 part in 10 to the -12 power. Using multiple GPS frequencies (to help correct for the nasty effects of the ionosphere) can improve that by another factor of ten or more, but at the cost of precision thermal control at my end. Right now my GPS time standard is sort of protected, but still drifts a couple of degrees C over the course of a day. I'll have to cut that by a factor of ten or more, but other Time Nuts already do that, maintaining temperature stability of their gear within .2 degrees C.

...the things some of us do for fun!

Wow. I envy you.

Happy Chinese New Year.

Not the normal people . . .

Just the nerdy geeks like thee and me !
