I don't use Orbitron, but there is something a little odd here. Celestrak
gets the Keps from Spacetrac, and according to the Orbitron site, they get
theirs from Celestrak and another site which seems to get at least some of
theirs from the same place. I am not saying people aren't seeing something,
but it is almost certainly not the accuracy or timeliness of the Keps.
Perhaps a formatting issue?

I am a fan of PocketSat ... Once you use it, you'll appreciate it. It is not
inexpensive at $25. As a matter of fact, of the 150+ apps I have on my iPod
touch, it is actually the most expensive app I have acquired.
But I have been with this program since the Palm version was released. You
get excellent product support from the author and a support YahooGroup for
questions. It painlessly downloads the AMSAT Keplerian data (or others) and
I consider PocketSat the ULTIMATE n satellite tracking software for this
platform.

February 23 CubeSat Launch From Vandenberg AFB
AMSAT News Service Bulletin 051.01
From AMSAT HQ SILVER SPRING, MD.
February 20, 2011
To All RADIO AMATEURS
BID: $ANS-051.01
NASA will launch the Glory satellite, an Earth-observation satellite
from Vandenberg Air Force base, California on February 23 at 0809 UTC.
Secondary payloads include student cubesats from the University of
Kentucky, University of Montana, and University of Colorado.
KySat-1, University of Kentucky
-------------------------------
436.790 MHz Beacon and FM downlink
Commercial S-band downlink
http://ssl.engineering.uky.edu/missions/orbital/kysat1/about-kysat-1/
The primary mission objective for KySat-1 is educational outreach.
For educational purposes KySat-1 can be commanded via mobile ground
stations using amateur radio frequencies. Mobile ground stations will
be taken to schools around the state for children to have their first
direct interaction with a satellite. Grade K-12 students and their
teachers will be able to upload/download images and audio files, and
will also have the capability to command the satellite to take photos
using ground station software developed by the University of Kentucky
Space Systems Laboratory.
The KySat-1 Team is requesting amateur satellite operators listen for
the 436.790 MHz beacon after launch. Amateur stations who copy packets
or beacons are invited send their data (decoded packets, audio record-
ings, signal reports) to ssl@xxxx.xxx.xxx.
The FM modulated pseudo-CW beacon transmits every 5 minutes at 32 wpm.
The message that will be transmitted is "KYSAT-1 ... followed by the
battery voltage to the tenth volt, and the processor temperature to
the hundredth degree C.
The FM modulated AX.25 encoded digital beacon transmits every 2.5 min-
utes. The digital beacon consists of a header, six binary-coded deci-
mal numbers separated by commas, and a 8 "bit" bitfield consisted of
eight ascii bytes showing either a "1" or "0". Full details of the
packet format:
http://ssl.engineering.uky.edu/missions/orbital/kysat1/operations/
Explorer-1 [Prime], University of Montana
-----------------------------------------
437.505 MHz Downlink 1200 bps KISS/Custom Non-Coherent FSK
Every 15 seconds worldwide
http://ssel.montana.edu/e1p/
The primary mission consists of critical space weather observations
for space weather forecasting and specification. The cubesat will
monitor the flux of trapped electrons in the horns of the inner and
outer radiation belts of the Van Allen radiation belts.
The E1P telemetry beacon consists of essential state of health infor-
mation and a quick look payload data product. The quick-look data con-
sists of one second averages of the intensity of energetic particles
encountered along the spacecraft trajectory as provided by our Geiger-
Mueller Counter.
A telemetry decoder can be downloaded from:
http://ssel.montana.edu/e1p/?page_id=8
Hermes, University of Colorado
------------------------------
437.425 MHz Downlink
http://spacegrant.colorado.edu/
The primary mission is to 1) Create modular and extensible satellite
subsystems; 2) Utilize S-Band frequencies to communicate at higher
data rates than those obtainable with Ultra-High Frequencies (UHF);
3) Characterize Hermes' orbital environment and satellite status to
validate models and design.
The primary communication system for the satellite is a UHF system that
transmits using a monopole antenna. The radio is a COTS Yaesu VX-7R which
transmits telemetry data using a TNC that was built by students.

To All RADIO AMATEURS
BID: $ANS-051.02
The ARISSat-1 satellite is still inside the ISS. Roscosmos has announced
that the satellite will be deployed during the next EVA in July of this
year. The US team is trying to get clarification from Roscosmos about the
"weak batteries" condition causing the satellite not to be deployed this
week. The news item can be found on the Roscosmos web site,
http://www.federalspace.ru/main.php?id=2&nid=11374 .
Roscosmos also announced that the satellite will be turned on inside the ISS
and use an external antenna on 12 April 2011. This is to celebrate the 50th
anniversary of Yuri Gagarin's first manned space flight. AMSAT will support
this event and issue certificates to those stations reporting reception of
the ARISSat-1 signals.
Tony Monteiro, AA2TX has an excellent article describing the ARISSat-1 power
system using the Russian Olan suit battery in the upcoming AMSAT Journal that
should be mailed to members next week.

University Nanosat-6 Winner Announced
AMSAT News Service Bulletin 051.06
From AMSAT HQ SILVER SPRING, MD.
February 20, 2011
To All RADIO AMATEURS
BID: $ANS-051.06
The team from the Houghton, Michigan college won first place in this year's
University Nanosat Program (UNP) Nanosat 6 competition with their Oculus-ASR
nanosatellite . The UNP competition was conceived in 1999 as a means to
"sustain and promote university research and education focused on small
satellites. This program was developed by the Air Force Office of Scientific
Research (AFOSR) in conjunction with the Air Force Research Laboratories Space
Vehicle Directorate (AFRL/RV). For this
competition a nansat is defined as 50kg
in mass (or less) and 50 x 50 x 60 cm or smaller.
The name Oculus comes from its operating as an
"orbiting eye" for the Department
of Defense. The DoD (and many other organizations) have a vested interest in
the observation and tracking of the many asteroids neighboring the earth.
According to the MTU Aerospace Enterprise team blog Oculus-ASR should launch
in
2013. The MTU nanosat has shape-shifting capabilities that are important to
ground-based observations and measurement. Imaging of the asteroids and other
space objects will then be compared with ground-based observations too. The
Oculus-ASR's work will be of great importance to the DoD's need to know what
is
orbiting the earth and what those objects are doing.

(ARISS) contact was held between astronaut Paolo Nespoli, IZ?JPA and Istituto
Comprensivo Statale ?E. Fermi ? A. Oggioni,? Villasanta, Monza Brianza, Italy
via telebridge station VK5ZAI in Australia. During the ISS pass Nespoli
answered 19 questions and exchanged greetings with the youth. An audience of
approximately 200 students and others were on hand for the contact and
afterwards, students sang the well known hit "Volare" which means "To fly."
Regional and local media and newspapers covered the event and streaming video,
provided by AMSAT-Italia, received 80 connections.
On-orbit astronaut Cady Coleman, KC5ZTH participated in an ARISS contact with
Lake Silver Elementary School students in Orlando, Florida on February 10 via
radio station LU8YY in Argentina. Coleman
answered 14 questions as a large crowd
of students, parents and guests gathered for the event. The school put
together
a comprehensive education plan to compliment this ARISS contact.
An ARISS contact was held between Lillestr?m videreg?ende skole, Lillestr?m,
Norway and Cady Coleman, KC5ZTH on the ISS on
Friday, February 11. Station W5RRR
in Houston, Texas handled the radio connection. Over 150 people assembled for
the event and listened as the astronaut fielded eight questions, mainly in
Norwegian. The contact was the highlight of a science and applied technology
curriculum.
National Institute for Astrophysics ? Astronomical Observatory of Bologna,
Bologna, Italy took part in an ARISS contact on Saturday, February 12 via
telebridge station LU8YY in Argentina. Italian astronaut Paolo Nespoli, IZ?JPA
participated from the ISS, answering 16
questions. Approximately 150 people were
present for the contact which occurred during the Bologna science festival,
?Scienza in Piazza,? held February 3 ? 13. The festival focuses on schools,
promoting science through hands-on exhibitions and conferences and is backed
by
the Italian Space Agency (ASI). Regional and local media and newspapers
covered
the event.

Satellite tracker pro is the one I use more than the others I have. Main
reason: it will show the Doppler shift during a pass. A big help in
reminding me to tune.

I should have been more specific.? I run SatPc32 in two computers.? The one
that runs LVB has ISS about 40 min behind the other computer.? All other
satellites are right on.? I have up dated the keps on both computers.?
Confused??

I guess that depends on what you are trying to look with. I use Nova
for windows and it will tell how old the keps are for the selected
satellite by selecting AutoTracking > Summary. That resulted in:

The 3rd line shows the age of the keps. Yes, those really are 3 1/2
years old...
If you look at a TLE file, the epoch time is the 3rd element in a 2
digit year followed by the 3 digits before the decimal and a bunch after
the decimal point. So in the TLE below, the epoch time was 32.75507474
days into 2006.
