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@amsat.org. 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@amsat.org.

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.

can be found on-line at: http://www.unisec.jp/unitec-1/en/top.html
