Re: Elevation System

I agree on TV rotors. Its an excellent inexpensive way to get elevation. The U100/110 is what I use as well and its well suited because you can put the boom right through the rotor. There are some nice pictures of setups using these rotors on this sites: http://www.rotorservice.com/press3-alliance.htm <- my setup imitates this one ... http://home.wavecable.com/~ko6th/ http://users.wbsnet.org/n0yk/cushcraft.htm And there’s a QST article on this in the Dec 1998 issue You can even build a controller for computer control but I’m currently rotating elevation and azimuth manually.

Mounted on their side, they seem to perform very well. Just keep things balanced, and protected from the weather and they should be happy.

Hi folks, Delfi - C3 uses partial deployed solar panels and whilst having other on board problems is still sending data which I monitor on a regular basis. Remember also that it does not use batteries and is therefore only functional when in sunlight. Temperatures must be quite high on such a small area - Just a thought.

[Launch Alert] Delta IV Heavy Launch
by Rick Tejera 19 Jan '11

19 Jan '11

Hose of you on the west coast may be interested. Clear Skies Rick Tejera Editor SACnews, Public Outreach Coordinator Saguaro Astronomy Club Phoenix, Arizona www.saguaroastro.org saguaroastro(a)cox.net K7TEJ, AMSAT 38452 -----Original Message----- From: launch-alert-bounces(a)mailman.qth.net [mailto:[email protected]] On Behalf Of Launch Alert Sent: Tuesday, January 18, 2011 21:21 To: Launch Alert Subject: [Launch Alert] Delta IV Heavy Launch LAUNCH ALERT Brian Webb Ventura County, California launch-alert-editor(a)earthlink.net http://www.spacearchive.info 2011 January 18 (Tuesday) 20:09 PST ---------------------------------------------------------------------- DELTA IV HEAVY LAUNCH SCHEDULED Vandenberg AFB News Release 2011 January 18 VANDENBERG AIR FORCE BASE, Calif. - The first West Coast Delta IV Heavy Launch Vehicle is scheduled to launch from Space Launch Complex-6 here Jan. 20 at 1:08 p.m. PST. This will be the largest rocket ever to launch from the West Coast of the United States. "This launch marks a significant milestone in our nation's space capability" said Lt. Col. Brady Hauboldt, launch director. "We've really restored a national capability for heavy lift on the Western Range, something we have not had since the last of the Titan IV-Bs flew out of Vandenberg. This extends our ability to cost effectively deliver payloads of all sizes and compliments." The launch follows three years of preparations and $100 million in base infrastructure upgrades at SLC-6. It makes Vandenberg unique in providing the full spectrum of space lift capability delivering payloads of all sizes to orbit aboard the Minotaur through Delta II, Atlas V and now the Delta IV, said Hauboldt. While this is the first Delta IV HLV from Vandenberg, it will be the fifth in the program's history. The first launch occurred in January 2004 from the East Coast. The rocket will carry a national security payload for the NRO. ---------------------------------------------------------------------- LAUNCH VISIBILITY AND VIEWING The Delta IV Heavy slated to lift-off from Vandenberg AFB on Thursday is a rocket enormous size and power. For observers in close proximity to the launch pad at south base, the launch should be impressive. However, for observers further away, the display will be more subdued because of the propellants the rocket uses and the time of day. The Delta IV Heavy launch vehicle consists of three liquid oxygen and hydrogen fueled Delta IV rockets that are joined together. The vehicle does not use any solid fuel rocket motors. Unlike solid fuel rockets or liquid fuel rockets that use solid fuel strap-on motors for extra thrust, vehicles that rely entirely on liquid propellants produce very little to no smoke trail. Such vehicles may create a contrail when they pass through an area of the atmosphere called the contrail zone, but this only lasts several seconds. Burning solid rocket fuel produces a tremendous amount of light. Burning liquid rocket propellants, on the other hand, also produce light, but the amount is much less and the flame is semi-transparent or clear. The fact that the launch is scheduled for the early afternoon will further impact launch viewing. The Sun will be high above the horizon and the launch will occur against a bright sky background. This will greatly reduce the maximum launch viewing distance. Taking the above factors into account, persons without prior knowledge of the launch may accidentally see it with the naked eye as far away as 25 miles. People who are specifically looking for the launch may be able to see it without optical assistance as far away as 50 miles. Observers using binoculars or a telescope could possibly see the launch as far away as 100 miles provided they look at the right area of the sky at the right time. People within 50 miles of the launch site or the Delta IV Heavy's flight path should be able to hear the launch. In outlying areas, the sound will probably arrive a few minutes after liftoff and consist of a low frequency rumble. The best place to view the launch will probably be near the south end of the base. The idea is to get as close to the launch site as possible while avoiding trespassing on government or private property and staying clear of any low clouds or fog. Regarding viewing areas, Vandenberg AFB Public Affairs recommends the public go to Surf Beach to view the launch. But to hear the countdown net they need to go to the Corral Road viewing location. Maps are located on the Vandenberg AFB Public Affairs Facebook page at: www.facebook.com/30thSpaceWing The launch should be visible to the naked eye provided you are close enough. For better view, use binoculars (tripod mounted binoculars are even better). Perhaps the best instrument for viewing the launch is an astronomical telescope. Astronomical telescopes are especially well suited for launch viewing and may provide an impressive view of the Delta IV Heavy in flight. Regardless of where you go to view the launch, park safely, be aware of traffic or any other hazards, and obey the instructions of military and public safety personnel. ---------------------------------------------------------------------- LAUNCH AND COUNTDOWN STATUS For launch and countdown status for the Delta IV Heavy/NRO launch, consult the following sources: Web Sites with Countdown Status: www.spaceflightnow.com/delta/d352/status.html Webcasts: www.ulalaunch.com/index_webcast.html Satellite Feeds: Begin Transmission (bars and tone) - 12:15 P.M.

SATCONTROL_FCD v.0.9.1
by Mike Rupprecht 18 Jan '11

18 Jan '11

All, Finally, I uploaded a new version of SATCONTROL_FCD (V. 0.9.1). The software is using Mike's newest ExtIO_FCD_M0MJW.dll (must be in the same directory). I made also some changes in the ini file. Please use this new version. It's all in the ZIP file. I got some questions regarding the MSWINSCK.OCX. That winsck.ocx is a windows library file for the Windows TCP/IP stack and I use it for connecting a timeserver. To register it, go to start->run and type in "regsvr32.exe C:\Windows\System\mswinsck.ocx" (without quotes) and hit enter. That should register it. If you don't have it or it's corrupted get one here: http://www.ocxdump.com/cgi-bin/testwrap/downloadcounts.cgi?rt=count <http://www.ocxdump.com/cgi-bin/testwrap/downloadcounts.cgi?rt=count&path=oc xfiles/M/MSWINSCK.OCX> &path=ocxfiles/M/MSWINSCK.OCX (or google .) If you delete or comment out ("#") this line TIMESERVER in your sat.ini the software will not try to connect the timeserver. Otherwise the software connect this timeserver and will update your system clock. Download zip file here: http://www.dk3wn.info/files/SatControl_FCD.zip 73, Mike DK3WN
