[amsat-bb] USNA Sat Status (day 3)

Yesterday @jasonrdavis (LightSail) tweeted: 
We may not get a new TLE until Monday, and apparently these aren't posted publicly - though I keep a TLE link at http://sail.planetary.org/missioncontrol

 Congratulations Bob! It looks like another set of successful USNA
satellites.

I noticed Space Track isn't publishing keps for these as of yet. I know this
has happened with previous DOD launches that had secondary payloads. Do you
know if they will eventually provide them to the owners of the satellites
(like previous launches) for them to distribute? I'd like to be able to
track these automatically, and the current 6 minute difference is a bit much
error for an AO-13 class system.

PSAT Summary - Day 3

* PSAT packet telemetry is OK, Digipeater will be off (secondary mission)
* PSAT PSK31 transponder is ON with 28.120 MHz uplink! (primary mission)
* WOD data fixed.  Spin data now available.  Right now it is at 3 RPM with
+Z pointing at Sun
* Launch TLE elements (below) are 6 minutes ahead of satellite
* PCSAT.APRS.ORG web page is now also capturing PSAT telelmetry downlinks
* BRICSAT telemetry has been heard but is cycling OFF due to low power
* BRICSAT PSK31 downlink (also FM) has also been heard barely (when ON)
* USS Langley not heard

Only fault so far is the loss of the 4 day-fail-safe backup reset circuit
(1 of 3) fail safe backup RESET capabilities.  The lack of WOD data was
because we had a LOW-POWER bits set that was holding it off.

BRICSAT PSK31 transponder is on identical frequencies as PSAT's.  You can
tell them apart because one has PSK Telemetry on 315 Hz and the other is on
365 Hz.  Both on the UHF FM downlink 435.350 MHz

SUMMARY:

PSAT:      145.825 - 1200 baud AX.25 telemetry - digi off
PSAT PSK31#1:  435.350 FM down, 28.120 SSB PK31 uplink - Brno University
Xponder

BRICsat:  437.975 - 9600 baud telemetry downlink every 20s BRICsat PSK31#2 -
same as PSAT but PSK TLM on 375 Hz (PSAT on 315 Hz)

USS Langley - 437.975  9600 baud telemetry

ULTRASat3  <these now predicting 6 minutes ahead of actual satellite>
