LVB Tracker USB serial port driver for Windows 7 x64?
by Bill Bordy, NJ1H 22 Dec '16

22 Dec '16

Has anyone located a driver for the LVB Tracker internal USB to serial port adapter on Windows 7 x64? If not, has anyone reverted to the serial port connection on LVB Tracker and used an external USB to serial port adapter successfully with SatPC32 on Windows 7 x64? I have an Edgeport multiple USB to serial port that has drivers for Windows 7 x64 that I will use if I have to. I would prefer using the LVB Tracker with its USB to serial adapter if someone has another solution. 73, Bill NJ1H

AO-16 telemetry 3 Oct 2010
by Mark L. Hammond 01 Jul '16

01 Jul '16

Hi All, Here is a quick AO-16 update. On Sunday I turned AO-16 long enough to get some telemetry packets. The satellite would remain on for less than one minute after being commanded on. A quick test of the "bent pipe" voice mode repeater was successful. . The "hardware watchdog timer problem" is still evident; as expected, spacecraft temperatures are insufficient to keep the transmitter ON (needs to be above 15 deg C). Orbit projections suggest that satellite illumination conditions will not result in increased temperatures for nearly 10 years. Command stations do periodically turn AO-16 "ON" to check on its condition and see if the hardware timer problem has "automagically" fixed itself (which in not anticipated, but who knows...).

The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. Please send any amateur satellite news or reports to: ans-editor at amsat.org. In this edition: * ESA Education Office announce six CubeSats chosen for Phase 1 Initiative * 13 Colonies Special Event Includes Satellite Operations * 2013 AMSAT-UK International Space Colloquium Starts July 19, 2013 * Two Lithuanian Amateur Radio CubeSats Plan 2013 Launch To ISS * July Space Station Spacewalks To Be Previewed And Broadcast On NASA TV * Upcoming ARISS Contacts * Satellite Shorts From All Over SB SAT @ AMSAT $ANS-181.01 ANS-181 AMSAT News Service Weekly Bulletins AMSAT News Service Bulletin 181.01 From AMSAT HQ SILVER SPRING, MD. June 30, 2013 To All RADIO AMATEURS BID: $ANS-181.01 ------------------------------------------------------------------------------- ESA Education Office announce six CubeSats chosen for Phase 1 Initiative Six student teams and their supervisors have gathered at ESA's ESTEC centre in The Netherlands for the kick-off of the new Fly Your Satellite! Programme under the ESA Education Office. On June 26-28, ESA experts will introduce the objectives and present the activities to be performed during the first phase of the programme. In January, ESA's Education Office announced the 'Fly Your Satellite!' initiative. This is aimed at offering student teams the opportunity to become familiar with good engineering practice to build and perform satellite testing in order to increase the chances of a successful mission. The 2013 edition of the programme is however only focusing on testing selected university-built satellites that are already at an advanced stage of development. 'Fly Your Satellite!' builds on the success of the 'CubeSats for the Vega Maiden Flight' pilot programme. This culminated in 2012 with the launch of seven student-built CubeSats on the first flight of the new ESA Vega launcher. The focus of the kick-off meeting will consist of coordinating the activity to be performed during the first phase of Fly Your Satellite! enabling the teams to complete the construction of their satellite. This will include extensive satellite testing in ambient conditions under the supervision of ESA specialists who will decide which satellites should participate in the next phase of the programme. The second phase will see the satellites tested in the simulated conditions of outer space and in those the satellites will experience at launch. These will include vibration and thermal-vacuum tests. The six CubeSats chosen for Phase 1 are: Robusta-1B from France will validate a radiation test methodology for specific transistor components. Oufti-1 from Belgium will demonstrate the D-STAR digital communication protocol and validate high-efficiency solar cells. ConSat-1 from Canada will analyse radiation characteristics in the South-Atlantic Anomaly, and test technology payloads. [email protected] from Italy will test an Active-Attitude Determination Control System. AAUSAT4 from Denmark will test an improved version of student built AIS (Automated Identification System) receivers. Politech.1 from Spain will carry a student built C-band communication system, a "GEODEYE" Earth Observation camera for academic purposes, and solar wind experiments.

It will be preceded by a "Hands-on" CubeSat Workshop. This free workshop will take place at the nearby University of Surrey on Friday, July 19 and this will be followed, at the hotel, by the usual Colloquium "Beginners Session" in the late afternoon. It is anticipated that both the FUNcube-1 and FUNcube-2 missions will be launched later this year and the FUNcube team will be on hand to talk about the missions and the planned educational outreach. A full demonstration of the Engineering Model, which has been performing flawlessly for almost a year, will also be provided. Further details and booking information at http://amsat-uk.org/colloquium/colloquium-2013/ [ANS thanks Trevor, M5AKA for the above information] ------------------------------------------------------------------------------- Two Lithuanian Amateur Radio CubeSats Plan 2013 Launch To ISS It is hoped that two Lithuanian satellites will be among the CubeSats sent by Nanoracks LLC to the International Space Station (ISS) on the SpaceX CRS-3 mission in November, 2013. They will be deployed from the ISS by the JEM Small Satellite Orbital Deployer (J- SSOD) of the Japan Aerospace Exploration Agency (JAXA). The Kaunas University of Technology is developing LituanicaSAT-1 while the Lithuanian Space Federation is working on LitSat-1. 2013 is the 80th anniversary of the historic flight by Lithuanian pilots Steponas Darius and Stasys Gire.nas in the airplane Lituanica. On July 15, 1933, they took off from Floyd Bennett Field in New York and flew across the Atlantic Ocean, covering a distance of 6,411 kilometers without landing, in 37 hours and 11 minutes. Tragically they crashed by the village of Kuhdamm, near Soldin, Germany just 650 km from their destination of Kaunas in Lithuania. LituanicaSAT-1 plans to carry a VGA camera, GPS receiver, 9k6 AX25 FSK telemetry beacon and a 150 mW V/U FM voice transponder.

NASA's Johnson Space Center in Houston will host a NASA Television briefing to preview the spacewalks at 2 p.m. EDT Tuesday, July 2. Reporters may attend the briefing at Johnson and other participating NASA centers, or ask questions by calling Johnson's newsroom at 281-483-5111 no later than 1:45 p.m. Tuesday. Briefers will include: -- David Korth, NASA spacewalk flight director -- Ernest Bell, Spacewalk 22 spacewalk officer -- Karina Eversley, Spacewalk 23 spacewalk officer Flight Engineers Chris Cassidy of NASA and Luca Parmitano of the European Space Agency will conduct the spacewalks July 9 and July 16 from the station's Quest airlock. Each spacewalk is scheduled to last 6 1/2 hours. Cassidy and Parmitano will replace a space-to-ground communications receiver and wireless video equipment and install power and cables for a Russian multipurpose laboratory module that will be launched later this year. The new module will serve as a research facility, docking port and airlock for future Russian spacewalks and will replace the Pirs module. Cassidy, who is designated EV1 for the spacewalks, will wear a U.S. extravehicular mobility suit bearing red stripes. The spacewalks will be the fifth and sixth of Cassidy's career. Parmitano, who is designated EV2, will wear a spacesuit with no stripes and will be making the first two spacewalks of his career. He will become the first Italian astronaut to walk in space. Both spacewalkers will wear helmet cameras to provide up close views of their work. NASA TV coverage of the spacewalks will begin at 7 a.m. on both July 9 and July 16. Both spacewalks are scheduled to begin at 8:10 a.m. For NASA TV streaming video, schedule and downlink information, visit: http://www.nasa.gov/ntv For more information about the International Space Station and its crew, visit: http://www.nasa.gov/station [ANS thanks NASA for the above information] ------------------------------------------------------------------------------- Upcoming ARISS contact with Scuola Secondaria grado "Arturo Toscanini", Capiago Intimiano, Italy and Scuola Media Massimiliano Kolbe, Vercurago, Lecco, Italy An International Space Station school contact has been planned with participants at Scuola Secondaria 1? grado "Arturo Toscanini", Capiago Intimiano, Italy and Scuola Media Massimiliano Kolbe, Vercurago, Lecco, Italy on 29 June.

Logbook of the World & AO-73
by Clayton Coleman 04 Dec '13

04 Dec '13

I attempted to upload a QSO using AO-73 as a satellite name in Logbook of the World. Since the satellite was a recently assigned this OSCAR number it appears the ARRL does not yet recognize it. I've opened a ticket with the LoTW helpdesk to resolve this issue. 73 Clayton W5PFG

Re: AO-73 keps
by Ronald G. Parsons 03 Dec '13

03 Dec '13

Using the keps from this morning (epoch 13330.154), the Doppler corrections by SatPC32 are much closer than yesterdays keps. I got the following frequencies from a nearly overhead pass about 1722 UTC. The frequencies are the frequency “at the satellite” calculated by SatPC32 to place the center of the telemetry in the middle of my 3.0 kHz USB passband. Thus the frequency of the center “at the satellite” are 1.50 kHz higher than these. Elevation xx where the frequency is 145935.xx MHz 5 .90 10 .85 15 .80 20 .75 30 .68 40 .65 50 missing 60 .59 70 .52 60 .50 50 .49 40 .47 30 .41 20 .37 15 .34 10 .29 5 .24 Thus a change of only about 660 Hz over the entire pass.

ICube-1 reception reports wanted
by Andrew Garratt 30 Nov '13

30 Nov '13

I have been messaging with Khurram Khurshid the manager of the ICube-1 team and they are struggling a little ".. we received icube for a couple of days using FunCube / HumSat TLE's but not anymore we are looking for our own TLE's but haven't been able to track icube for the past few days" They may officially ask for assistance but after unexpectedly making the first signal report back on the 21st November, I thought I was just ask if anyone could keep an ear out. ICube-1 was released as part of the UNISAT-5 payload and if still functional is in CW mode on 145.947MHz and the message is "First Cubesat of Pakistan" Some info/links http://amsat-uk.org/2013/11/25/unisat-5-mission-update-november-24/ http://nerdsville.blogspot.co.uk/2013/11/im-famous-and-icube-1-move-and-vel… The ICube-1 facebook page https://www.facebook.com/ICUBE1 Thanks Andrew Garratt M6GTG
