KiwiSAT at the Technology Convention (Auckland, 2013)

by Jim Tittsler

At the Technology Convention hosted by the Auckland VHF Group this weekend, we had a chance to see KiwiSAT in operation. Fred ZL1BYP and Ian ZL1AOX arranged to bring the satellite in its "clean cabinet" to the convention so that the audience would have a chance (hopefully, a first and last chance) to see it. Ian had brought along his station (and dummy loads) and demonstrated commanding the satellite and collecting telemetry across the room. I thought it was pretty exciting that they would go to the amazing effort (and risk, gulp :-) of bringing the satellite and its support equipment to the convention so that the rest of us could see it. The satellite is on the air from a well elevated site just south of Auckland... so hams in the area can try listening for it or even working through it during its final tests.

Re: fcd and orbitron TLE differences

by Mark L. Hammond

I've never seen his program be picky about TLEs. How about this one: http://www.celestrak.com/NORAD/elements/amateur.txt Mark N8MH At 05:50 PM 3/30/2013 -0400, Lizeth Norman wrote: >Where do I download the TLE that works with the FCD program that Mike dk3wn >wrote?? >I ran into this bug last time down this road. > >It's definitely a bug.

fcd and orbitron TLE differences

by Lizeth Norman

Where do I download the TLE that works with the FCD program that Mike dk3wn wrote?? I ran into this bug last time down this road. It's definitely a bug. Then again with all the software blowhards out there, it's probably a feature. IIRC the bug lies in the fact that no one, anywhere can agree on the format for the TLE's, let alone what might be in them. It comes down to the hex whitespaces, I think.

google earth tracker update

by Joseph Armbruster

All, As some of you know, i've been hard at work on my ge-satellite-tracker [http://code.google.com/p/ge-satellite-tracker/]. Here is a brief update on what i've implemented since my last email: - The concept of ground stations was added. Configured ground stations are drawn on the Earth. - Ground stations -> satellite line of sight indicators are rendered - Keps can now be cached and you can work in an "offline" mode (amsat or spacetrack) - Satellite footprints are plotted (using a spherical earth model approximation) I have multiple blog posts with screenshots, you can access them from the project page. Next on my agenda is to add ground station field of view and re-factor all of the ugly kml-template cruft. If you have any special requests or suggestions, let me know. Joseph Armbruster

DynaCube CubeSat

by M5AKA

An article about the DynaCube CubeSat is on the Southern African Amateur Radio Satellite Association (SA AMSAT) site. Note the estimate of how much it could cost to launch the 1U Cubesat - 1,300,000 Rand which is £92,000 or $140,000, see http://www.amsatsa.org.za/DynaCube.htm On the AMSAT-UK site is: New Version of STRaND-1 Telemetry Decoder http://amsat-uk.org/2013/03/28/new-version-of-strand-1-telemetry-decoder/ ---- Trevor M5AKA AMSAT-UK http://www.amsat-uk.org/ Join or Renew your AMSAT-UK membership at http://shop.amsat.org.uk/shop/category_7/Membership-of-AMSAT-UK.html ----

Re: STRaND 1 and AAUSAT3 TLE (No longer part of tle-new.txt)

by GW1FKY＠aol.com

Hi Mark, Thanks for your information and the follow up action. Just to add - Please note Strand-1 has now also been moved to the Cubesat directory from Recent Launches. Regarding AAUSAT -3 if anyone is asking about further action it was originally 39086U. ( 130009B) Thanks also to PE0SAT for his initial observation on the omissions.

tres cool

by Lizeth Norman

Gentlemen, With apologies to the local viri going around, I've got a site to point out: http://www.exa.ec/pegaso/PEGASO.swf 14 pages from the beginning, BACKWARDS!!!!!!!!!. there is a page showing a proposed still from their package. Nice to look at and will be looking for it on the air. It's on 910 MHz so the gear needed will be homebrew and an antenna fabricated. IIRC wa5vjb has one of these in his bag of tricks. Have fun and don't break anything. Norm n3ykf
