Description

AMRAD/EYESAT-1 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 AMRAD-OSCAR-27 once in orbit. The other two amateur spacecraft were KITSAT-OSCAR-25 (KO-25) and Italy-OSCAR-26 (IO-26).

AO-27 is a secondary amateur communications payload carried aboard the EYESAT-1 experimental MICROSAT satellite built by Interferometrics Inc. of Vienna, Virginia.

The commercial side of the spacecraft's mission is the experimental monitoring of mobile industrial equipment.

The amateur equipment aboard the satellite was constructed by members of AMRAD, a technically-oriented, non-profit organization of radio amateurs based in the Virginia suburbs of Washington, D.C., to meet the needs of amateurs for a platform to conduct digital satellite communications experiments.

AO-27 is presently operational as a FM "repeater" in the sky. Ordinary UHF and VHF FM amateur radios can be used to communicate through this satellite. The amateur radio transponder is operational on most weekends.
