COMPASS-1 End of mission

Posted on by

Dear supporters and friends of our COMPASS-1 mission,

First, let me thank you very much for your support in trying to save the life of our COMPASS-1 satellite during the last days, but also during the last years of “routine” operations. It seems that our mission now comes to an end. The projected lifetime of COMPASS-1 was half a year. The tiny guy has outperformed this value by Compass-1a factor of more than seven. April 28th would have been it’s 4th birthday and if it was a human, it would now be about 500 years old (Cubesat-years are short). So, if you have more important things to do (and I guess so), we can not expect you to continue your efforts in saving its live. With your support, you have made things possible that we would never have been able to achieve with our own resources and I appreciate your support very much. So, COMPASS-1, rest in peace. (Nevertheless, if you still want to try to awake it from the dead, feel free to do so.)

I hope that we will soon be able to build and launch COMPASS-2 and that you will be
still available, all over the world, as a ground station to command and fly our new
bird. We will keep you informed.

Cheers and thanks for all,

CubeSat to use propulsion

Posted on by

SatMagazine March 2012The March issue of SatMagazine features a 4 page article by Randa Relich Milliron, CEO and Co-Founder of Interorbital Systems.

Interorbital Systems plans to launch a number of amateur radio CubeSats along with dozens of TubeSats on it’s Neptune 9 rocket.

Among the CubeSats to be launch by Interorbital Systems is Euroluna’s Romit1 which aims to be the first CubeSat to use propulsion to significantly raise its orbit, from 310 to 700 km.

The Interorbital Systems article appears on page 90 and is followed on page 94 by an article on the Space Foundation which aims to promote science, technology, engineering and mathematics (STEM) in schools.

HAMSAT VO-52 Recovery Operations

Posted on by

VU2WMY/Mani

With regrets, we confirm the non-availability of the transponder on HAMSAT VO-52 since 28th February 2012. This is the first ever interruption in the services of HAMSAT since May 5th 2005.

The following question came from ISRO:

If possible, try to find out who has last operated HAMSAT payload transponder on 28th and at what time.

OZ1MY/Ib answered the following:

In my record I heard and briefly used the transponder on the pass with AOS here in Copenhagen, Denmark at 0826 UTC on the 28th, February. On the next pass with AOS at 1003 UTC it was not on.

VO-52 PreFlightVO-52 Telemetry:

There where some questions about how to find out what the state is of VO-52. When looking in to that, I found out that Telemetry and Groundstation command is done outsite the amateur frequency. TM is done on 137MHz en TC on 149MHz. The exact frequency is only know by ISRO as confirmed by PE1RAH in a conversation between him and SV1BSX.

HAMSAT telemetry: Posted by William, 25 May’05 Hi, The HAMSAT gives only telemetry to the ISRO groundstation on none ham frequencies. ISRO use it to check the status and to switch on/off the transponders and change attitude when needed. The telemetry will only be activated by ISRO groundstation and is not for public use. The frequencies are secret and only for ISRO. 73 pe1rah William.

André Kuipers active as PI9ISS

Ham Radio PI9ISS Andre-Kuipers

This evening PI9ISS (André Kuipers) was active from the ISS space station. The signal was loud and clear but there were many stations that wanted to make a connection so for me this time it wasn’t possible to make a connection. During the pass at 19:30 CEST we will give it another try.
