AMSAT News Service Bulletin 066.01 >From AMSAT HQ SILVER SPRING, MD. March 7, 2010 To All RADIO AMATEURS BID: $ANS-066.01 East Coast APRS Satellite Launch 11 March! You will be able to see it too over most of the mid-atlantic. I don't see a launch time or any other info yet. Here is what I have received: ----------------------------------------------------- A sounding rocket with amateur satellite operating on 144.39 MHZ APRS will rise to 100 miles or so for an 8 minute mission. The rocket (I think) is the Hall 12.067. The payload is called SOCEM/ADAMASat. There is a computer program and GUI to interface to your PC so you can grab the telemetry live. It is on: http://ssl.engr.uky.edu/adamasat_free_gui.exe It's a one shot deal, so I'm gonna have a backup TNC and HYPERTERM collecting everything. ADAMASat is the Antenna Deployment and Mono-filament Actuator Satellite. It's a 2U CubeSat designed by Kentucky Space as part of SOCEM, the Sub-Orbital CubeSat Experimental Mission. ADAMASat, which is scheduled to launch on Hall 12.067 out of Wallops Flight Facility on 11 March, will fly in space for roughly 8 minutes performing an engineering experiment and transmitting data down to Earth via APRS packets. More information on ADAMASat is available at http://ssl.engr.uky.edu/suborbital/adamasat Kentucky Space is hereby releasing to the AMSAT-NA community the ADAMASat FREE GUI, a free 32-bit Windows binary for amateur radio operators in the Eastern United States who are interested in tracking ADAMASat on its launch day. The GUI is a standalone application and upon opening it on his/her computer, the HAM will be greeted with a popup window which explains the steps required to track the payload. All that is needed is a Windows machine, a radio and TNC which can receive on 144.390 MHz, a serial or USB cable, and a suitable location. The GUI parses the APRS packets as they are received, graphing temperatures on-board the payload and reporting status of the mission in real-time. It also includes instructions on e-mailing the packet log to Kentucky Space to aid in post-processing, and a built-in aggregator for the official ADAMASat Twitter RSS feed. Disclaimer: Kentucky Space provides the GUI "as is" without warranties of any kind, and shall not incur any liability for any damages connected to the use of the GUI. [ANS thanks Bob, WA4APR, for the above information] /EX SB SAT @ AMSAT $ANS-066.02 A new interference threat to the Ham Bands AMSAT News Service Bulletin 066.02 >From AMSAT HQ SILVER SPRING, MD. March 7, 2010 To All RADIO AMATEURS BID: $ANS-066.02 FCC to Permit Rescue Radio Robot in the 430 to 450 MHz Band Reports initially carried in the February 26, 2010 edition of Amateur Radio NewslineT Report 1698, and on the QRZ.com website say the FCC has issued a waiver of the Part 90 rules to permit a company called Reconrobotics Incorporated to sell a remote controlled security robot that will operate in the 430 to 448 MHz band. This is spectrum that is primary to the Federal Radiolocation Service but also encompasses the Amateur Service weak signal, satellite and repeater subbands. The waiver permits Reconrobitics to manufacture and sell a device called the Recon Scout. This is described as a device designed for state and local law enforcement and firefighting agencies, and secur- ity personnel in critical infrastructure industries. The Recon Scout can be thrown, dropped, or launched into potentially hazardous areas and can provide real-time video to an operator located a safe dis- tance away. Typical applications will include such things as checking a building prior to forced entry, searching vehicle undercarriages for explosives and searching for survivors in a burning structure. The Recon Scout transmits the analog video signal to the operator on one of three six megahertz channels. These are 430 to 436 MHz, 436 to 442 MHz, and 442 to 448 MHz. Reconrobotics says that multiple channels are necessary in order to avoid interference during incidents where multiple Recon Scouts are in use, but that such situations should be rare. The company's now approved proposal is that the first unit sold to a responding organization would operate on 442 to 448 MHz. That happens to be where thousands of ham radio repeaters operate. The 436 to 442 MHz version being sold only to entities that already own the 442 to 448 MHz version, and the 430 to 436 MHz version being sold only to entities that already own both of the others. In approving the waiver, the FCC told Reconrobotics the Recon Scout will have to operate on a secondary basis where it cannot cause inter- ference and is not protected from interference to all Federal users and licensed non-Federal users including radio amateurs. The FCC also warned prospective users that operation of the Recon Scout in an unauthorized manner will subject licensees to Commission enforce- ment action and license revocation. It also said that widespread improper use of the device could lead the Commission to stop grant- ing or renewing Recon Scout authorizations.

March 7, 2010 To All RADIO AMATEURS BID: $ANS-066.03 SK: Dave Toth, VE3GYQ AMSAT received the sad news of the passing of a friend this week noting the passing of Dr David Toth, VE3GYQ. Dave was the President Emeritus of Tucson Amateur Packet Radio (TAPR) Group. He was an early member of TAPR, a long time supporter of AMSAT and he gave of his time and talents to promote technical endeavors in Amateur Radio. Former AMSAT President Tom Clark, K3IO remembered Dave, "He was always a friend of AMSAT, giving up personal vacations to help with the integration of AO-40 in Orlando. For many years, he was the glue that held TAPR together." Former AMSAT Board Member, Bob McGwier, N4HY recalled that, "Dave was an important player in the earliest days of packet radio in that he helped promote packet and supported it with on the air hardware. As a board member and President of TAPR, he helped TAPR become the principal support for Open HPSDR, a project to promote the development of hardware and software for software defined radio use by Amateur Radio. He will be sorely missed by all who knew him." Dr. Toth graduated from the University of Western Ontario Medical School in 1978. He practiced family medicine in London, Ontario but moved to the U.S. in 1993 to began a career in emergency medicine. He was a partner of Premier Health Care Services, in Dayton, Ohio, and worked at Lima Memorial Health System and St. Rita's Medical Center until the time of his illness.

March 7, 2010 To All RADIO AMATEURS BID: $ANS-066.04 Next week, March 14th, our semi-annual time change will occur. And of course, do we gain or loose an hour? The words Spring ahead and Fall back should come to mind as this is the rule. More modern Atomic Clocks (as they are called) Set themselves without any manual adjustments. I had a clock that was pre programmed for earlier DST changes and sent me to work late one Monday morning. Get out your pencils and mark your calendar For this event. I'm sure the News media will advise you for several days prior to this required Adjustment to happen, but, someone will not get the word. Please tell that person. Thank goodness GMT (UTC) stays the same no matter what time of the year it is. Computers too are Pre programmed but satellite program users should make sure time was corrected properly. We Wouldn't want you to miss that Sat QSO you planned for all week. Don't forget the 1.26 micro second Adjustment that the Earthquake in Chile has created.

March 7, 2010 To All RADIO AMATEURS BID: $ANS-066.05 AO-51 Survives Close Encounter With FORMOSAT-3 AMSAT-NA VP Operations, Drew KO4MA, received notification from the US Joint Space Operations Center, located at Vandenberg Air Force Base, California on Sunday, February 28 warning that AO-51 would have a close approach to another satellite, FORMOSAT 3-D, on Monday at 1056 UTC. This occurred over the Eastern US, with many stations on hand capable of receiving telemetry from AO-51 before and after the near miss. Drew said, "The predicted miss distance was 953 meters, which is over 3000 feet overall but the radial difference between the two orbits was only 39 meters." Steve, W3HF noted, "Given the orbital uncertanties of both satellites, an orbit separated by only 39 meters could mean that distance may become eaten up rather quickly!" In preparation for the close encounter, Drew shut off the S band tran- smitter and turned on the digital downlink at 2 watts, with telemetry transmitted every 5 seconds. The next morning, on March 1, Drew was able to post a message that AO-51 was alive and well, "It looks like we are fine. A second warning email this morning from the Air Force called it even closer, but everything was working at LOS this pass." FORMOSAT-3 is a constellation of satellites launched on April 15, 2006. It is a joint U.S.-Taiwanese project with major participants including the University Corporation for Atmospheric Research (UCAR), the National Science Foundation, the Naval Research Laboratory (NRL), the Air Force Research Laboratory (AFRL) on the U.S. side and the National Space Organization (NSPO) on the Taiwanese side.

Telemetry for a newbie
by Peter Wilson 07 Mar '10

07 Mar '10

Hi all, My Gulf antenna arrived last week and togther with my recently aquired FT-736 I should be up and running within the month. My initial reason for building my satellite station was to receive and decode telemetry from the sats, hoping to monitor their condition over a period of time. I realise that some transmit TLM via morse, some via AX25, and some via 96K packet. What would be the best sat to start with, especially AX25? - Does AO51 send TLM all the time or only over the USA? What resource is the best for reading? Does the F&-736 need modifying for high speed packet reception? Many thanks for any help. Peter G8KEK AMSAT-UK 6897

If you search for the above topics you will find papers from teams who have implemented satellite control using these methods. Of course the computer algorithms to process the data collected and calculate attitude is complex. You will not get detailed information from the USA due to their ITAR laws. 73 David
