08:16 UTC strong downlink signals over Europe
… listen to the complete pass (10 minutes)
If I listen to the pass I am left wondering wheter it is what we want, what we need.
And again I remember of some golden rules published many times not only by Ib, OZ1MY:
It is obviously about time to repeate a few good points about operating via the FM repeater satellites.
1. Do not transmit if you can not hea
2. When the satellite is busy – limit the number of QSO’s to ONE
3. Do not call over an ongoing QSO
4. A valid QSO just needs the call and the report
5. Give way to weak stations like /p and /m
6. Allow DX-peditions to make as many QSO’s as there are callers

AAUSat3 CW beacon: oz3cub b7.2 t-3
Project ELaNa, NASA’s “Educational Launch of NanoSat” managed by the Launch Services Program at the Kennedy Space Center, announced on February 10 that the AMSAT Fox-1 cubesat has been selected to join the program.
NASA will work with AMSAT in a collaborative agreement where NASA will cover the integration and launch costs of satellites deemed to have merit in support of their strategic and educational goals.
Watch for full details to be published in the AMSAT Journal.
AMSAT teamed with the ARRL to write and deliver the 159 page educa- tional proposal to NASA. Letters documenting the importance of AMSAT’s satellites in the education programs at the ARRL and also at the Clay Center for Science and Technology at the Dexter and Southfield schools in Brookline, MA, were important parts of our proposal.
AMSAT President Barry Baines, WD4ASW said, “The ELaNA Launch oppor- tunity marks AMSAT’s return to space after the conclusion of the successful ARISSat-1/KEDR flight. We need to get the flight Fox-1, along with an operational flight backup satellite, built, integrat- ed, tested, and delivered. Our ability to provide a spacecraft and get it launched is dependent upon the active support of our donors who wish to see Fox-1 fly.”
AMSAT Vice-President of Engineering, Tony Monteiro, AA2TX noted this will provide a launch opportunity for AMSAT’s next generation of FM repeater satellites with features and operation beyond the experience of AO-51. AMSAT’s Fox-1 Engineering Team is making progress developing the advanced satellite that will provide these features:
+ Fox-1 is designed to operate in sunlight without batteries once the battery system fails. This applies lessons learned from AO-51 and ARISSat-1 operations.
+ In case of IHU failure Fox-1 will continue to operate its FM repeater in a basic, ‘zombie sat’ mode, so that the repeater remains on-the-air.
+ Fox-1 is designed as the immediate replacement for AO-51. Its U/V (Mode B) transponder will make it even easier to work with modest equipment.
+ From the ground user’s perspective, the same FM amateur radio equipment used for AO-51 may be used for Fox-1.
+ Extending the design, Fox-2 will benefit from the development work of Fox-1 by adding more sophisticated power management and Software Defined Transponder (SDX) communications systems.
The Fox-1 Project presents an opportunity to literally put your call- sign on the Fox hardware. AMSAT is looking for major donations to help underwrite the cost of solar cells/panels, one of the more significant expenses of the project.
These solar cells are needed for the flight unit as well as for the a flight spare. As Fox-1 will have solar cells on all six sides of the spacecraft and given the relatively small surface area available on each side (at most 4″ by 4″ per side), AMSAT needs to invest in high efficiency solar cells to gain as much power as possible to operate the spacecraft.
Several opportunities to make your donation to keep amateur radio in space include:
+ Return the form sent with the letter to reply with your donation for the Fox-1 Project.
– All donations over $40 will receive a Fox pin.
– Donations of $120 or more qualify you for AMSAT President’s Club
+ Call Martha at the AMSAT Office +1-888-FB AMSAT (1-888-322-6728)
+ Paypal donation widget on the main page at: http://www.amsat.org
+ Paypal donation widget for Project Fox at: http://www.amsat.org/amsat-new/fox/
+ You can also go to the Paypal site and send your donation to

07:49 UTC Space shuttle Atlantis deployed a small, eight-pound, 5” X 5” X 10” solar cell technology demonstration satellite, called PicoSat, from a canister in the shuttle cargo bay.
Pico-Satellite Solar Cell Experiment (PSSC) is a picosatellite designed to test the space environment by providing a testbed to gather data on new solar cell technologies. This capability will allow for gathering spaceflight performance data before the launch of new satellites with the new solar cell technology as the primary power source. Presently, the two U.S. solar cell manufacturers, Spectrolab and Emcore, are starting production of a new generation of High Efficiency Solar Cells on a two to three year cycle.
The Pico-Satellite Solar Cell (PSSC 2) testbed was scheduled to be deployed after Atlantis undocks from the International Space Station during STS-135/ULF7, becoming the last satellite ever deployed by the Space Shuttle Program. The satellite, also known as “PicoSat,” will perform two DoD experiments during its in-orbit lifetime. First, the Miniature Tracking Vehicle (MTV) experiment goal is to demonstrate the capability of a nano-satellite to serve as an orbiting reference for ground tracking systems while demonstrating 3-axis attitude control, solid rocket propulsion for orbit modification, adaptive communications and active solar cell performance monitoring in a nanosatellite platform. An on-board Global Positioning System (GPS) receiver will provide accurate time and position information to facilitate tracking error analyses. The second experiment, Compact Total Electron Content Sensor (CTECS), will demonstrate a CubeSat form factor space weather sensor with the capability to detect ionospheric density. It uses a modified commercial GPS receiver to detect differences in radio signals generated by occulting GPS satellites.
The PicoSat is 5″ x 5″ x 10″ and weighs 3.7 kg. It is integrated onto Atlantis for the STS-135 mission under the management and direction of the DoD Space Test Program’s Houston office at NASA’s Johnson Space Center. PicoSat will be ejected shortly before shuttle re-entry into a low (less than 360-km altitude) orbit with an expected orbital lifetime of three to nine months, depending on solar activity. Multiple on-board megapixel cameras will image Atlantis as the satellite departs, thus supplying the last in-orbit photos of NASA’s workhorse human space transportation system for the last few decades.
After the satellite’s orbit lowers for approximately one month, four ammonium perchlorate solid rocket motors will provide 40 Ns of impulse each and could extend orbital lifetime by an additional two months or alternatively, actively deorbit the satellite. The PSSC 2 bus, MTV and CTECS experiments will be controlled by a primary ground station at The Aerospace Corporation in El Segundo, Calif., and secondary stations that comprise the Aerospace Corporation Internet-based Picosatellite Ground Station Network.
The satellite has two radios for redundancy, both operating on 914.7 MHz, and both using an omni-directional patch antenna.
FAST-2 is alive, needs a reset, and has not been commanded yet. FAST-1 and FAST-2 remain attached as planned.
FAST-2′s 1200 bps 3-minute beacon (145.825 MHz) reverted to 9600bps at two minute intervals over night last night. This indicates that the TNC reset itself and the on-board microprocessor wasn’t responsive to restore the settings. This is not serious, but we can’t reset things until we can command the satellites.
FAST-2′s 1200bps beacon had not been updating for the last couple of days which told us at the least, the I2C bus had locked up some time back. We knew this would happen periodically before launch, so this behavior is not unexpected.
FAST-2 has been actively rejecting 9600bps crosslink requests from FAST-1 at 10-minute intervals due to the I2C bus lockup. They had previously been heard by several stations around the world crosslinking the first few orbits after launch Friday evening.
FAST-2′s downlink frequency seems to be about 2-3kHz higher than advertized, so we know the coms subsystem is not at room temperature.
FASTRAC-1 (Sara Lily)
FAST-1 is alive, is beaconing, is attempting to crosslink with FAST-2, but the 437.435 MHz downlink is much weaker than predicted. Nobody to my knowledge has been able to decode beacon data from FAST-1 yet.
FAST-1′s UHF beacon (437.345 MHz) is much weaker than FAST-2. We have heard it occasionally but just above the noise floor.
FAST-2′s responses to FAST-1′s connect requests lead us to believe that FAST-1 is most likely functioning normally.
