SB SAT @ AMSAT $ANS-316.01 New ANS Editor
AMSAT News Service Bulletin 316.01 From AMSAT HQ SILVER SPRING, MD. November 12, 2006 To All RADIO AMATEURS BID: $ANS-316.01
I am pleased to be back in the seat as an editor of ANS. It's been about 18 months since I've done it and it feels like no time has gone by. I hope that my contribution will go a little way to encouraging and enlightening others about the worldwide AMSAT mission.
On a practical front, I'm involved with preparing the WWW telemetry pages for the ANDE satellite and getting involved with the Global Educational Network for Satellite Operations (GENSO), more details later in this bulletin.
73, Dave, G4DPZ

SB SAT @ AMSAT $ANS-316.03 NASA activates UHF SDR aboard MRO
AMSAT News Service Bulletin 316.03 From AMSAT HQ SILVER SPRING, MD. November 12, 2006 To All RADIO AMATEURS BID: $ANS-316.03
On Monday, 6 November 2006, the Electra software-defined UHF transponder aboard the Mars Reconnaissance Orbiter was activated in order to relay communications to and from the Spirit rover on the surface of Mars. During the 4.2 minute MRO pass, 31 megabits of data from Spirit were acquired at a return link rate of 128 kilobits per second while simultaneously sending a small forward-link file to the rover. This is the first deep-space use of a software-defined radio by NASA.

SB SAT @ AMSAT $ANS-316.04 Want Eagle to be built and launched?
AMSAT News Service Bulletin 316.04 From AMSAT HQ SILVER SPRING, MD. November 12, 2006 To All RADIO AMATEURS BID: $ANS-316.04
Recent legislation passed by Congress and signed by President Bush can help make that happen. The law, called the Pension Protection Act (PPA), includes a provision enabling AMSAT to raise substantially more money than might have been previously possible.
You know how important money is to getting Eagle into orbit.
Basically, here's the story on how the new law can help Eagle fly!.
The PPA provides that U.S. taxpayers with IRAs who have reached the age of 70-1/2, may contribute to qualified charities, part or all (up to $100,000), of the money they must annually withdraw from their IRAs.
Thus, many AMSAT members and other supporters of the amateur radio space program have a marvelous opportunity to keep the Eagle project on track.
If you must withdraw a certain amount from your IRA each year, there is a big advantage to making such withdrawals as direct contributions to AMSAT rather than merely receiving the distributions and then contributing in the usual manner. Under PPA, the amount you contribute directly is NOT counted as income and thus may put you into a lower tax bracket. It may also reduce the percentage of your Social Security income subject to taxation.
Key provisions of the new legislation to keep in mind:
1. Donors must hold either a conventional or Roth IRA.
2. Donors must be at least 70-1/2 years of age.
3. Contributions must be made directly from the IRA to the charitable organization not to a donor- advised fund, private foundation, gift annuity or trust.
4. Donations may be made this year and next only, and must be made by December 31, 2006 and December 31, 2007.
5. The maximum amount a contributor may donate each year is $100,000.
6. Direct contributions to qualified charities from IRAs, in accordance with the PPA provisions, are NOT counted as taxable income.
If you are 70-1/2 or older and have an IRA, you are in a position to take advantage of this potential windfall for the Eagle project. AMSAT urges you to first check with your tax advisor for specifics regarding your individual situation, then ask your IRA custodian to transfer to AMSAT part or all of what you are required to withdraw. Be sure to have this transfer completed before December 31st.
Let's all of us do our part to get Eagle into orbit.
* Have your IRA custodian call the AMSAT office to get information on how to transfer your contribution. The number 301-589-6062. Office hours are 10 AM to 6 PM EST.

SB SAT @ AMSAT $ANS-316.05 Looking for a Digital designer to help with PCSAT-3
AMSAT News Service Bulletin 316.05 From AMSAT HQ SILVER SPRING, MD. November 12, 2006 To All RADIO AMATEURS BID: $ANS-316.05
PCSAT-3 will hopefully be similar to PCSAT-1 and PCSAT2 including a PSK-31 transponder and of course the usual packet digipeaters.... AND...
But it also will have a large surface area that we want to see if we can HEAR micrometeor impacts, and with four microphones and DSP see if we can locate the point of impact. This will require working with a high-end PIC processor that has a DSP code operating at up to 1 MHz sample rate (500 KHz bandwidth), 12 bit resolution, and sensitivity down to 10ths of a milli-volt.
Supposedly we have a "software" guy, but we don't have a digital designer to lay out the 80-pin-PIC processor board, including all the low noise front end to avoid the inevitable noise in the system and a huge amount of FLASH ram to record the data.
If it works, and the PIC detects a hit, then not only would it save the data science purposes, but then we can reply it on the FM downlink as audio for everyone to hear. Expectations are maybe 3 hits per day average?
Anyway, if anyone is an excellent digital designer, with time on their hands and is interested in this project, let me know. Thanks Bob, WB4APR

SB SAT @ AMSAT $ANS-316.06 Global Educational Network for Satellite Operations
AMSAT News Service Bulletin 316.06 From AMSAT HQ SILVER SPRING, MD. November 12, 2006 To All RADIO AMATEURS BID: $ANS-316.06
An ESA Assessment Study for this project began in June 2006 and a large number of the study team attended the AMSAT-UK 2006 Colloquium as part of the SSETI contingent. AMSAT-UK representatives (including the Ed.) were invited to attend their break-out meeting by Neil Mellville of ESA.
In the meeting, AMSAT-UK received a briefing on the purpose of GENSO. Which is to provide a global infrastructure that will be available for future educational satellite projects. By increasing communication time from an average of 3% to a potential 60%, it will become possible to access spacecraft data in real time at low cost.
As a result of this, AMSAT-UK joined with ESA, the SSETI Association, UNISEC, and several universities around the world, to determine the technical feasibility of the project and define a comprehensive set of technical requirements with suggested design solutions.
A month later, the first workshop was held at the University of Tokyo to discuss the proposal and the potential for inter-continental collaboration. The response from the amateur radio and academic communities was particularly promising.
The implementation plan produced at the second workshop, held in ESTEC in late September, included work packages, a preliminary schedule and a budget framework. On 5 October, this plan was presented to the International Space Education Board during the International Astronautical Congress in Valencia.
The Board gave the go-ahead to start the design and implementation of the software and hardware, with objective of running a pilot phase in around a years time. They are planning a workshop next February to discuss our progress and the core features should be ready for testing by mid-2007. If all goes according to plan, they hope to have the network fully operational from November 2008 onwards.
Over the coming months, ESA will provide funding for software development and overall project management, with the other space agencies on the board, CSA, JAXA and NASA, sponsoring involvement from Canada, Japan and the USA respectively.
“One of the key aspects of this project will be that the network is developed ‘by students for students’, with the technical support and guidance of the space agencies and the radio amateur community,” said Neil Melville of ESA.
AMSAT-UK has been asked to define the typical ground station in terms of hardware and to provide supporting software. Therefore, watch out for a questionnaire appearing on AMSAT-BB for your thoughts.
The data collection and ground station software, developed as part of the project will be made available to the AMSAT community.
