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

SB SAT @ AMSAT $ANS-129 02 Power Management Software Operational on AO-51
AMSAT News Service Bulletin 129 02 From AMSAT HQ SILVER SPRING, MD May 9, 2010 To All RADIO AMATEURS BID: $ANS-129 02
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

SB SAT @ AMSAT $ANS-129 04 Current UNITEC Information
AMSAT News Service Bulletin 129 04 From AMSAT HQ SILVER SPRING, MD May 9, 2010 To All RADIO AMATEURS BID: $ANS-129 04 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
