Very interesting ITAMSAT documentary

This documentary shows the preparation and launch of the first Italian amateur radio satellite,  September 26, 1993. It was encoded and uploaded from original video master.

IO-26 carried a Mode JD (145 to 435 MHz) Digital Transponder using the 1200 bps AX.25 protocol store-and-forward PACSAT Protocol Suite communications system.


 Thanks Very much AMSAT-UK

Satellites in a box – Radio Aurora Explorer video

In this video radio amateur Professor Jamie Cutler KF6RFX highlights the ability of CubeSats to test new technology in space at low cost.

The Radio Aurora Explorer (RAX) mission has proven that scientific information can be gathered from a CubeSat, which is a small satellite encased within a box and attached to a spacecraft to achieve orbit.
The scientific data gathered by RAX has been published in peer-reviewed science journals.

KN-SAT1 Prototype Subsystems Design and Testing

The KN-SAT1 CubeSat, which will have a VHF downlink, is being developed at the University Of Khartoum.

Mahmoud Esawi has made available a video which shows KN-SAT1 Prototype2 subsystems design and testing.

Prototype 2 has a variety of functions:
• Send it’s location received from the GPS receiver.
• Taking a picture and send it back to earth using AX.25 protocol.
• Receive Tele-commands from earth to be executed, like:
• Restart the subsystems.
• Download a picture.
• Take a shot at specific GPS location.
• Change the Tele command key password.

In this Service, you can write messages onto PRISM’s on-board memory via FM packets uplink.
Also you can command PRISM to downlink the stored messages in FM packets. Thus, PRISM can be used as a kind of message box. Also, you can evaluate FM packets performance of your ground station designed for amateur radio satellites.
The followings are three commands you can use:

• Information Command : Read latest ID of written messages.
• Write Command : Store your message into PRISM.
• Read Command : Read a message of designated ID.
