ITAMSAT was one of three amateur satellites that was launched together on a Arianne V59 rocket from French Guiana at approximately 0147 UTC, 26 September 1993. It was later designated Italy-OSCAR-26 once in orbit. The other two amateur spacecraft were KITSAT-OSCAR-25 (KO-25) and AMRAD-OSCAR-27 (AO-27) (aka Eyesat-A).

IO-26 was built by AMSAT-ITALY. Its mission is to store and forward amateur radio messages like AO-16, LO-19, UO-22, KO-23 and KO-25. IO-26's operation is identical to AO-16 and LO-19.

The ITAMSAT Command Team can be contacted via internet: Alberto Zagni, I2KBD, i2kbd@amsat.org or Luca Bertagnolio, IK2OVV, ik2ovv@amsat.org or on Compuserve HAMNET.

As with any major undertaking, there are many people involved in building a satellite. ITAMSAT is a labor of love: the love of amateur radio as a hobby and the love of research and exploration. Read here as I2KBD thanks the IO-26 team.
