Re: Linux-Sat Tracker

Hello It depends on the Linux in question. I use Debian 6.0 (Squeeze) and I use the following in tandem to get a nice view of satellites: a) predict and predict-gsat b) gpredict I think predict-gsat along with predict running in the background is a better UI overall and gives a nicer view, but YMMV. --Vikas On Mon, Jan 7, 2013 at 3:00 PM, <amsat-bb-request(a)amsat.org> wrote: > Date: Mon, 7 Jan 2013 00:34:58 -0800 > From: Kevin Deane <summit496(a)live.com> > To: "amsat-bb(a)amsat.org" <amsat-bb(a)amsat.org> > Subject: [amsat-bb] Linux-Sat Tracker > Message-ID: <BLU174-W21362A62C1EAA1875A966583250(a)phx.gbl> > Content-Type: text/plain; charset="iso-8859-1" > > > Trying to utilize a couple old computers using Linux and am trying to > install a sat tracker.

G5500 question
by Roy 06 Jan '13

06 Jan '13

Hi Bob, Long time. I have seen this happen in the old KCT controller. Full right rotation is the max pot rotation also. In the KCT case, the control bits that were set to initiate rotation sometimes got set in the full right turn setting and were left that way. Can you determine if the rotor was actually sent to 450 or if it turned, uncontrolled, to the right until the end of rotation limit switch (if one is present) was actuated stopping the rotor? If there is no limit switch, then a thermal switch may have repeatedly opened to protect the rotor from burnout. The rotation bits got set sometimes and were left set when the controller was powered off or the tracking program was closed, etc. when the rotor was moving. This also happened on some PCs anytime the KCT was initially installed and before the calibration was completed. In those cases we had to unsolder the R-L-U-D rotor control leads until the calibration was completed. Your case doesn't resemble this latter problem, however. 73, Roy -- W0SL

Orbital's initial flight of the Antares-110 vehicle will carry PhoneSat into low earth orbit. The vehicle will be launch- ed from a new launch pad LA-0A at Wallops Island, where the former Conestoga launch pad was located. Phonesat carries an amateur radio payload on 437.425 MHz, has been chosen as one of the winners in the Aerospace category for the Pop- ular Science magazine "Best of What's New 2012" awards. PhoneSat is a technology demonstration mission consisting of three 1U CubeSats intended to prove that a smartphone can be used to per- form many of the functions required of a spacecraft bus. The satellite is built around the Nexus smartphone which will be run- ning the Android operating system and will be enclosed in a standard 1U cubesat structure. The main function of the phone is to act as the Onboard Computer, but the mission will also utilize the phone's SD card for data storage, 5MP camera for Earth Observation, and 3-axis accelerometer and 3-axis magnetometer for attitude determination. One of the nanosatellites, powered by the HTC Nexus One smartphone, will send back pictures of Earth. The other two, running on the Sam- sung Nexus S, will have two-way S-band radio allowing them to be controlled from Earth. With a short lifetime of only about one week, the satellites have no solar cells and operate on battery only. Also planned for this launch is the commercial DOVE-1 satellite for a technology demonstration nanosatellite based on the triple CubeSat form factor. It's mission consists of: + Build a low-cost imaging satellite with non-space, COTS components. + Show that a bus constrained to the 3U cubesat form factor can via- bly host a small camera payload. + Demonstrate the ability to design, produce and operate satellites on short schedules and low cost. Dove-1 plans to transmit its telemetry and image data to the ground on a proposed frequency of 145.825 MHz in the amateur radio band al- though this is a commercial mission.

Volunteers from the SSC and SSTL built STRaND-1 in their spare time. The STRaND-1 spacecraft will carry an Amateur Radio AX.25 packet radio payload on 437.575 MHz. It will be the UK's first "PhoneSat" carrying a Nexus Android Smartphone that will run a number of Space Apps. In addition it will have both a Resistojet and a Pulsed Plasma Thruster (PPT) module. The 'STRaND Data' App, one of the Space Apps that will run on the Smartphone was a spin-off of the work done by the AMSAT-UK FUNcube team. This App will collect satellite telemetry from within the sat- ellite and display it graphically on the Nexus One Display. The dis- play is observed by an on-board camera and the images transmitted to earth on Amateur Radio frequencies. Pictures taken during the BBC filming can be seen at https://www.facebook.com/pages/Surrey-Space-Centre/147861435274871 STRaND-1 on Facebook https://www.facebook.com/nanosats [ANS thanks AMSAT-UK for the above information] --------------------------------------------------------------------- Help Wanted: AMSAT News Service Rotating Editor Positions Available The AMSAT News Service (ANS) is responsible for researching, writing, editing, and publishing the weekly amateur satellite news bulletins.

The two stations had about an hour of common window where each had 15 to 20 degrees of elevation. JA6CZD uses a 2.4 M offset fed dish with a 22 watt SSPA. W5LUA uses a 2.4M offset fed dish and a TWT mounted on the feed support provid- ing 100 watts at the feed. JA6CZD sent Al a 559 signal report and Al gave Shichirou a 449 report. Both stations use linear polarity and must compensate for the 70 degrees of spatial offset between their locations. JA6CZD was used horizontal and Al used vertical polarization. The noise figure at both stations was under 2 dB. Al measured his Doppler Shift with his return echoes at 51 KHz at the start of the contact. The mutual Doppler Shift placed both at about 24048.108 MHz based on a center frequency of 24048.100 MHz. This shifted down in frequency as the schedule took place. W5LUA was GPS locked and JA6CZD uses an OCXO and a Rubidium standard to control frequency. [ANS thanks Al Ward, W5LUA for the above information] --------------------------------------------------------------------- Kline School Posts AMSAT Announcement The Kline School "Out of This World Experience" Raises $6500 for AMSAT Fox story, originally announced in the ANS-351 bulletins, now has some photos to accompany this event. (See: http://amsat.org/pipermail/ans/2012/000675.html) In conjunction with Kline School's ARISS contact on December 6 the students launched a Spell-A-Thon and raised $6,500 dollars for solar panels on Fox-1. Kline School posted coverage of AMSAT's write-up at: https://sites.google.com/a/klineschool.com/return-to-space/highlights https://www.facebook.com/pages/Kline-School/153838291839 (plus you get a preview of page 5 of the January/February 2013 AMSAT Journal under production.) [ANS thanks Kline School and The AMSAT Journal for the above information] --------------------------------------------------------------------- /EX In addition to regular membership, AMSAT offers membership in the President's Club. Members of the President's Club, as sustaining donors to AMSAT Project Funds, will be eligible to receive addi- tional benefits. Application forms are available from the AMSAT Office. Primary and secondary school students are eligible for membership at one-half the standard yearly rate. Post-secondary school students enrolled in at least half time status shall be eligible for the stu- dent rate for a maximum of 6 post-secondary years in this status. Contact Martha at the AMSAT Office for additional student membership information. And with that, please keep in mind when Christmas was over Rudolph had a chance to do something he had wanted to do for a long time. He made an appointment with a plastic surgeon because he was so sensitive about his looks. However, it wasn't his glowing pro- boscis that he wanted changed. He was proud of his nose and the help he had given Santa because of it. No, he was sensitive about his long ears which were much more prominent than the ears of the aver- age reindeer. So one week after Christmas, he underwent reconstruc- tive surgery, and since that time, January 1st has been celebrated as ... New Ears Day. 73, This week's ANS Editor, JoAnne Maenpaa, K9JKM K9JKM at amsat dot org
