My PC's clock keeps getting off by enough to cause problems on near
overhead passes. I've seen it off by more than 30 seconds. It is using
Internet synchronization, which happens once a week. Is there a way to
force Windows 7 to automatically update clock more frequently than once
per week. Please don't tell me to monkey with the Windows Registry. I
know PC clocks are notoriously inaccurate, but this is ridiculous.

Doesn't your prediction software have the option to put you clock right when
it starts?
Mine does.

Hi Larry,
I use EZTimeSync. It is free and you can set
how often you want it to update.

I use one of the following located at my site.:
ftp://bristor-assoc.com/pub/Amateur/atmtm22.exe
ftp://bristor-assoc.com/pub/Amateur/atomic-clock.exe
The first one allows multiple syncs during the day. The second once a
day. You can Google
the names and probably get newer versions, but have found these to work
well and have them on all of my systems.

Hi Larry,
Time synchronization is scheduled in the 'Task Manager' of Win 7.
Open 'Task Manager' and look for the item and edit it. Thanks for
bringing this to my attention as I just upgraded (?) to Win 7. I set
mine to sync at startup as I turn the PC off at night. My tracking
software (Nova) also does it when it is started. Also updates Keps.

Some of the internet time syncing tools recommended are not compliant
with Win 7 64-bit O/S. I will not be chasing those further and hope to
edit the time sync service that already exists in Win 7.

Well, I also screwed up. Should have said 'Task Scheduler' in Win 7.
The time service I use is time-b.nist.gov

Even though Larry doesn't want to play with the registry it is IMHO the
fastest and easiest, and, you don't have someone else' utility doing exactly
that automagically for you.
In WIN7 I've done...
HKLM\System\CurrentControlSet\Services\W32time\TimeProviders\NTPClient and
changed SPECIALPOLLINTERVAL to a decimal 3600 or whatever you want.

Three Additional Cubesats Aboard the JAXA Planet-C Launch
In addition to the UNITEC-1 University satellite bound for Venus
orbit on May 17 there will also be three additional cubesat class
birds aboard. These cubesats will be dropped off in low-earth orbit
prior to the Planet-C and UNITEC-1 satellites departure for Venus.
Three of the CubeSats, Negai*", WASEDA-SAT2, KSAT, being launched by
the H-IIA rocket on May 17 will be dropped off into a low earth orbit
but UNITEC-1 will continue following the JAXA's Venus Climate Orbiter
PLANET-C / AKATSUKI on its journey to Venus.

Power Management Software Operational on AO-51
AO-51 has now reentered a period of eclipses that will reach almost
20 minutes by July. Since the satellite has been in an extended period
of continuous illumination and very warm spacecraft temperatures, the
Operations Team will spend the next few weeks determining what the
batteries capacities are in the new environment.
AMSAT-NA VP Operations, Drew Glasbrenner, KO4MA enabled the power
management software on AO-51. The 435.300 repeater with the new PL
mode is programmed to run at 1.01 watt while in sun, and 290 milli-
watts while in eclipse. The low power mode will continute after exit-
ing eclipse until the solar cells recharge the batteries approximately
7.9 volts.
For this summer eclipse season, the eclipsed periods are while AO-51
is over mostly unoccupied Antarctica and surrounding areas. This means
when the batteries alone are supporting the transmitter there are not
likely to be any users. The power management software combined with the
PL, should mean we can protect the batteries from over-discharge, while
still providing the strongest possible downlink.
Observations from the southern hemisphere while entering and leaving
eclipse are very helpful. Post your reports on the AMSAT-BB or e-mail
your report to the AO-51 Operations Team at ao51-modes@xxxxx.xxx. AO-51
operators also monitor the Live OSCAR Satellite Status Page
(see: http://oscar.dcarr.org/). Analysis of AO-51's Whole Orbit Data
(WOD) files shows the distribution of the satellite's users.
See: http://tinyurl.com/2f83ezk
If the eclipse periods get too long too fast the repeater may shut off
due to a low battery voltage watchdog. If this happens, please email
Drew directly at ko4ma@xxxxx.xxx.

Amateur Radio Call for Assistance for UNITEC-1 Venus-Bound Satellite
On May 17 Japan's Space Agency JAXA plans to launch its Planet-C
Venus Climate Orbiter "AKATSUKI" mission to Venus. Also aboard will
be UNITEC-1, a 15 kg, 35cm cubed nano-satellite developed by twenty
two universities and colleges of UNISEC (University Space Engineering
Consortium).
UNITEC-1 be inserted into a Venus encounter trajectory and will become
the world first university satellite which goes beyond Lunar orbit. The
main mission of UNITEC-1 is to perform technological experiments of
on-board computers and test long-range, inter-planetary communication
using amateur radio frequencies:
Downlink Frequency: 5840.000MHz, band width 20MHz
Transmission Power: 4.8W/antenna, 9.6W total
Antenna: 2 Microstrip patch antennas
Modulation: AFSK/FM 1200bps during LEO flight
CW 1bps during Interplanetary flight
Due to development time and funding limitations UNITEC-1 does not
have an attitude control system resulting in a tumbling motion in
the inter-planetary trajectory. It will be impossible to maintain
full-time earth pointing of the 5840 MHz patch antennas. Consequently,
the 1 bps CW signal will detectable intermittently.
Tracking of the satellite should also be done using the same weak
downlink signal. UNISEC cordially invites world-wide AMSAT and other
amateur RF engineers to support the interplanetary team by receiving
the very weak RF signal, decoding it and enabling tracking during
the long journey to Venus. In the future they hope to develop a world
wide ground station network using the internet to relay your received
and decoded signals directly to the UNITEC-1 Mission Operation Center
in Japan so that the real-time signal analysis can be performed.
In addition to the telemetry content of the beacon the direction of
incoming RF signal and the amount of Doppler Shift will also be sent
to the Operation Center to continually estimate the satellite traject-
ory (position and velocity). This trajectory data will be available
to all of the world amateur ground stations fine tune their C-band
antenna tracking.
As the Earth rotates only the ground stations pointing toward UNITEC's
direction can receive the signal. This challenge can be overcome by
creating a global network of interplanetary-capable amateur radio earth
stations.
Full information about this exciting mission and amateur radio challenge
can be found on-line at: http://www.unisec.jp/unitec-1/en/top.html

1. Upcoming School Contacts
An Amateur Radio on the International Space Station (ARISS) contact was
scheduled for Nippon Boy Scout Amateur Radio Club in Mitaka-shi,
Japan on Tuesday, May 4 at 15:09 UTC. The Japan Boy Scouts have an
amateur radio club, JA1YSS and study amateur radio station operations.
The boys enjoyed speaking with Soichi Noguchi, a former Boy Scout.
The Smithsonian Institution National Air and Space Museum (NASM) in
Washington, D.C. was scheduled for an Amateur Radio on the International
Space Station (ARISS) contact on Space Day, Saturday, May 8 at 17:01 UTC
via VK4KHZ in Australia. The Education Division of NASM recruited
the young people who participated in the contact. Generally,
Boy Scouts and other groups are involved with this activity.
The Museum drew approximately 30,000 on this Saturday in May.
Komoro Higashi Junior High School in Komoro, Nagano,
Japan has been scheduled for an Amateur Radio on the International
Space Station (ARISS) contact on Friday, May 14 at 11:16 UTC. The
students have become especially interested in space due to Koichi
Wakata, the first long term Japanese astronaut on the ISS. Many
children chose to take a space themed course under their general
education requirement. As part of their studies, they visited
Nobeyama Radio Observatory and worked on radio kits. A JAXA
representative visited the school and gave a presentation on
space and the ISS. Through these activities, students enhanced
their knowledge of space, the ISS and communication using ham radio.
2. ARISS Contact Held at IARU Exhibition/European Parliament
Students from European School Brussels II were invited to the European
Parliament in Brussels, Belgium on April 27 to participate in an Amateur
Radio on the International Space Station (ARISS) contact with on-orbit
astronaut Timothy Creamer, KC5WKI. Other students remaining at the school
listened in to the contact via teleconference. Telebridge station
LU1CGB in Argentina provided the connection. The ISS hook-up was the
highlight of the ESA/IARU (International Amateur Radio Union) Region
1 exhibition, ?European Amateur Radio Benefiting Society.? Afterwards,
astronauts Frank De Winne and Robert Thirsk as well as cosmonaut
Roman Romanenko visited the exhibition and met with a group of 40
students to answer questions about their space missions. Several
Members of the European Parliament and assistants attended the event.
The American Radio Relay League (ARRL) and the Radio
Amateur Satellite Corporation (AMSAT) posted articles on this event.
