Kwangmyongsong-3 satellite
by Gregory Beat 09 Apr '12

09 Apr '12

Photos were released today of the Kwangmyongsong-3 satellite, planned to be launched from North Korea later this week. The rectangular box satellite appears to have a ~ 400 MHz 1/4 wave antenna on same side as sensors, and possibly Earth Observation (EO) camera. I have seen no data on frequencies to be used for EO camera. When I saw the first images of the satellite, it reminded me of a Surrey (SSTL) design from a decade ago. IF placed in a polar orbit, it would have a Western hemisphere ascension across eastern Brazil, Western Atlantic, and eastern Canada / Greenland. w9gb Sent from the new iPad

Hi, I'm doing some work with RESTful web services and have thrown together a prediction service that generates XML. For a URL of: http://websat.g4dpz.cloudbees.net/api/position/25544 (the ISS catalogue number) you get: <trackPosition> <altitude>392</altitude> <azimuth>0.0</azimuth> <catalogueNumber>25544</catalogueNumber> <elevation>0.0</elevation> <latitude>8.3</latitude> <longitude>263.4</longitude> <setNumber>327</setNumber> </trackPosition> adding locator and amsl (metres) http://websat.g4dpz.cloudbees.net/api/position/25544/locator/io82xl/amsl/200 you get: <trackPosition> <altitude>392</altitude> <azimuth>278.8</azimuth> <catalogueNumber>25544</catalogueNumber> <elevation>-41.2</elevation> <latitude>8.3</latitude> <longitude>263.4</longitude> <setNumber>327</setNumber> </trackPosition> The keps are collect every 12 hours from AMSAT (nasabare) and CELESTRAK (amateur) and the systems stores the latest keps for the catalogue number. Hitting the refresh key on the browser gives you the latest position. I've got more ideas for it: next N hours AOS/TCA/LOS for single satellite ditto for constellation of satellites satellite name aliases for catalogue number The code is written in Java based on my predict4java library and I'm quite happy to make it Open Source if any project would be interested. If you do try it, it may take a couple of seconds to start up as the server is in the Amazon Cloud and goes to sleep after a period of inactivity. 73 Dave G4DPZ

April 8, 2012 To All RADIO AMATEURS BID: $ANS-099.01 Fox-1 Project Educational Goals Align With NASA ELaNa Requirements 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. AMSAT will work with NASA 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. In an article published in the AMSAT Journal, AMSAT Vice-President of Engineering, Tony Monteiro, AA2TX noted that meeting NASA's edu- cational goals for Science, Technology, Engineering, and Math (STEM) was the cornerstone in the successful acceptance of Fox-1 into the ELaNa project. Fox-1 continues AMSAT's long record of success as an all-volunteer organization providing access to space communications for students in a curriculum setting as well the private citizen. The Fox-1 communication package provides a learning and techologi- cal stepping-stone using commonly available amateur radio equipment. Students gain first-hand experience in setting up and operating equip- ment, orbital prediction, communication to distant places, and growth in overall space literacy. In the classroom, Fox-1 will allow schools, teachers, and students to actively participate in space technology with a unique experimental hands-on learning approach that includes communicating through a satellite in orbit. All of the Fox-1 experiment and telemetry data will be collected and stored on our internet server and made publicly available for use in the classroom and shared with the CubeSat community. In addition to mentoring university student cubesat mission teams, AMSAT satellites have also hosted university experiments aboard our spacecraft. In addition to the communications package, Fox-1 will host an experimental payload developed as a capstone project at Penn State University. The Penn State project will have impact on future CubeSat systems as the students design, construct, and orbit an atti- tude experiment based on a 3-axis micro-electro-mechanical gyroscope. Fox-1 Project Reviews --------------------- The Fox-1 Team participated in a Merit Review and Feasibility Review with a panel including education and industry experts at the Doctorate level, a developer of 29 satellites, and directors of research. The results of the Fox-1 Merit Review found: + AMSAT "nailed" the NASA education requirements of the NASA Educa- tion Strategic Coordination Framework and the NASA Education Imple- mentation Framework. In fact, AMSAT has a history of space education that pre-dates most university programs. + The Fox-1 program will be accessible to an entire classroom or school with only the teacher or outside volunteer requiring an amateur radio license. + The archive of telemetry data collected during actual space flight will prove valuable in future educational projects that have yet to be imagined. The results of the Fox-1 Feasibility Review found: + While AMSAT relies on an all-volunteer development team the tre- mendous depth and experience of the Fox-1 team far exceeds the capability of a typical CubeSat team. AMSAT has developed its satellites this way for 40 years and has never missed a launch. + AMSAT does not rely on critical technology for flight and leverages our experience from prior successful missions: o 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. o 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. o 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. o From the ground user's perspective, the same FM amateur radio equipment used for AO-51 may be used for Fox-1. AMSAT's Fox-1 project timeline is based on targeting a launch in the second half of 2013. NASA will determine on which flight each of the Project ELaNa CubeSats fly. They have updated their CubeSat Launch Initiative web page including AMSAT's participation at: http://www.nasa.gov/directorates/heo/home/CubeSats_initiative.html [ANS thanks the Fox-1 Team for the above information] --------------------------------------------------------------------- AMSAT-NA Board of Directors Nominations It is time to submit nominations for the upcoming open seats on the AMSAT-NA Board of Directors. A valid nomination requires either one current Member Society, or five current individual members in good standing, to nominate an AMSAT-NA member for the position. Three directors and two alternate directors have terms expiring this year. The director seats open for election are held by Tom Clark, K3IO; Lou McFadin, W5DID; and Gould Smith, WA4SXM. The alternate dir- ector seats open for election are held by Mark Hammond, N8MH and Patrick Stoddard, WD9EWK. The three nominees receiving the highest number of votes will be seated as regular board members with two year terms. The two nom- inees receiving the next highest number of votes will be seated as alternate directors for one year. Written nominations, consisting of names, calls and individual signa- tures, should be mailed to: AMSAT-NA, 850 Sligo Ave #600, Silver Spring, MD, 20910. They must be received no later than June 15th. No other action is required. Nominations may also be made by electronic means including e-mail, FAX, or electronic image of a petition. Electronic petitions should be sent to MARTHA(a)AMSAT.ORG or faxed to 301-608-3410, and also must be received by June 15th.

[ANS Thanks AMSAT Secretary Alan Biddle, WA4SCA for the above information] --------------------------------------------------------------------- EPFL Announces Nanosat Ion Drive - To The Moon on 100 mL of Fuel An article posted on space-travel.com reported the EPFL University in Switzerland announced the first prototype of a new, ultra-compact motor that will allow small satellites to journey beyond Earth's orbit. (See: http://tinyurl.com/EPFL-IonMotor) EPFL said the MicroThrust ion motor will be capable of reaching the Moon using just a tenth of a liter of fuel. The complete thruster weighs just a few hundred grams and is specifically designed to pro- pel small (1-100 kg) satellites, which it enables to change orbit around the Earth and even voyage to more distant destinations - functions typically possible only for large, expensive spacecraft. Instead of a combustible fuel, the new mini motor runs on an "ionic" liquid, in this case the chemical compound EMI-BF4, which is used as a solvent and an electrolyte. It is composed of electrically charged molecules (like ordinary table salt) called ions, except that this compound is liquid at room temperature. The ions are extracted from the liquid and then ejected by means of an electric field to generate thrust. This is the principle behind the ionic motor: fuel is not burned, it is expelled. After six months of acceleration, the microsatellite's speed increases from 24,000 km/h, its launch speed, to 42,000 km/h. The acceleration is only about a tenth of a millimeter per square second, which trans- lates into 0-100 km/h in 77 hours. But in space, where there is no friction to impede motion, gentle but steady acceleration is the way to go. "We calculated that in order to reach lunar orbit, a 1-kg nanosatel- lite with our motor would travel for about six months and consume 100 milliliters of fuel," explains Muriel Richard, a scientist in EPFL's Swiss Space Center. A video about the MicroThrust has been posted at: http://www.youtube.com/watch?feature=player_embedded&v=YJlSI_l5g4M [ANS thanks Space-Travel.com for the above information] --------------------------------------------------------------------- European ATV-3 Edoardo Amaldi Arrives at ISS & Performs Reboost After a successful launch on March 23, the heaviest cargo ship ever has arrived and docked to the International Space Station. The 20-ton European ATV-3 cargo ship, named "Edoardo Amaldi" after the Italian physicist and spaceflight pioneer, made a "smooth and gentle" docking on March 28. It delivered 7 tons of food, drinking water, clothing, oxygen, spare parts and fuel for the 6-member ISS crew. A video of the docking with ISS can be viewed at: http://www.youtube.com/watch?feature=player_embedded&v=PorM-1F4jdo On Saturday, March 31 the ATV reboosted the space station's orbit to 389.8 km. The ATV's thrusters ran for 351 seconds, increasing ISS vel- ocity by 1.0 m/s and boosting average altitude by 1.73 km. This is a standard test performed as soon as possible after docking. The successful test burn means that ATV is ready for a series of larger planned reboosts (the first expected on 5 April) and to con- duct debris avoidance manoeuvres when necessary.

San Francisco High School Students Plan Near-Space Balloon Mission
by EMike McCardel 07 Apr '12

07 Apr '12

They following two articles were reported in the April edition of the Mount Vernon (OH) ARC Newsletter "CQ". Barry Butz, N8PPF is the father of Craig Butz, KJ6DYP, one of the teachers involved in the project. I thought I would post in event anyone was interested in following the ballon launch. IKAROS III BALLOON LAUNCH by Barry Butz N8PPF Very soon we will be joining our son Craig KJ6DYP and his students for their third near-space balloon launch. It will be in the Black Rock Desert in northwest Nevada on April 11. Two students and another teacher have recently earned their technician licenses. One of the students has participated in the project for three years and his newly issued call will be used on the ham radio carried by the balloon. You can track the balloon on http://aprs.fi/ by searching for KJ6VFJ-11. This will bring up a Google map showing the position along with speed and altitude data. Two pursuit vehicles will also be sending APRS positions using calls KJ6DYP-7 and N8PPF-1. Real-time updates will be sent over the Internet, as explained in Craigs article. Launch time is estimated as between 9:30 and noon Eastern time. The launch site is in a very remote area and I don't know if cell service or Internet will be available. Nevertheless, anyone interested should email me at n8ppf(a)mvarc.net beforehand and I will try to send last minute updates. San Francisco High School Students Plan Near-Space Balloon Mission Students in the space club at The Bay School of San Francisco have spent this school year planning a third near-space balloon mission. After several all-day meetings spent building the probe, the group plans to launch Ikaros III from the Black Rock Desert in northern Nevada on April 11, 2012 to recover images of the earth and the blackness of space along with atmospheric data from 100,000 feet altitude—three times as high as commercial airliners fly. The group is lead by Craig Butz, KJ6DYP (son of Barry Butz, N8PPF, who plans to attend the launch) and Feroze Munshi, KJ6UTH. Two students passed their amateur radio license exams in preparation for the mission: Nolan Van Dine, KJ6UIM and Jesse Greenfield, KJ6VFJ. Live updates on the mission and details about tracking the balloon and ground crew via APRS will be found on the project website: http://ikaros.xrg.us/livestream.html . Its APRS call will be KJ6VFJ-11. Ikaros III will use an all-new Arduino-based flight computer to collect, record, and transmit GPS location and atmospheric pressure and temperature data. Arduino is an open-source microcontroller platform that makes interactive electronic and robotic projects accessible to hobbyists. Both the tracking and data- logging circuit boards were constructed by students. The data board is a kit from Maker Shed that records data to an SD card, with temperature and pressure sensors added by the team. The “Trackuino” APRS tracking board was designed by Javier Martin EA5HAV and Kyle Crockett, KJ6KUV, both of whom have flown their own balloons. If all goes according to plan, Ikaros will also use the services of HAM social networking site 73s.com to send its own tweets with status reports from the edge of space under the handle @ikarosflight. Miniaturizing the equipment will also help the club meet its goal of getting the probe to even higher altitudes than previous missions. Ikaros III will be a follow-up to previous successful missions on May 22, 2010 and April 15, 2011. During a one-hour-thirty-three minute flight, Ikaros II flew from the hills east of the San Francisco Bay Area over the Central Valley, landing 57 miles away. It reached an altitude of 83,772 feet. During the flight, the payload got a taste of the harsh conditions beyond the protection of the Earth's atmosphere. Temperatures dropped as low as 76 degrees below zero and atmospheric pressure was 2% of what it is at sea level. Ikaros I reached 75,774 feet over Pinnacles National Park, and experienced 173 mile-per-hour winds in the jet stream.
