up with expectations
based on the satellite constellation at sample time.
Not to sound too optimistic, but this might just work. Let's go launch
this thing!

these boards with his setup.
* I programmed the CPLD on board #2 without error. Testing will be
easier with working code on the STM32.
* I tried holding Boot Select high and resetting the Venus 838, but
didn't get the amber light of life on either board.

* Gavin showed off the sleek new tm3k refactor, now known as tm4k.
* Andrew mounted jGPSv3 to the flight stack for more real-world testing.
* Kenny replaced the LTC Alpha WiFi with a red card like we use
everywhere else. (And blew up a spare with reverse voltage. Ooops.)
* Devin and Glenn tested
a matter of fitting them together. The next big question is: can we
still get GPS baseband and COTS lock from the radial patch antenna when
WiFi amps are on?

about the bits I understand and/or hack on GPS stuff more then. If
Friday and Monday don't work for your schedule, suggest another time and
I'll try to make it.

noise was enough to correlate the
pseudo-noise sequence from other satellite vehicles. This was done in
the basement, so I know it wasn't accidentally picking up any real
satellites.

account for this. Maybe some of the aliasing artifacts could be
compressed?
I don't have a good place to post this file at the moment.
Recommendations? I'll have it with me on a thumbdrive for the capstones
Thursday, Friday hackday and Sunday lab hours.

AIS data is not displaying at the FDT. Maybe a socat command on the tm3k
needs a fresh IP?
Future work:
- setup Nagios
- setup remote syslog everywhere
- install Splunk
- win!

Next, Theo will work magic on the STM32 to fire up the MAX2769 and CPLD.

of bare wire (length ~= diameter) was used to bridge the freshly exposed
trace to the pad/pin. No other changes required.

I have a dozen Pi's scheduled to arrive in July. If this isn't too
close to launch date, then I would be happy to commit one for PSAS use.
This is of course assuming that it would meet the needs of the
application.
