MESAT 1, MESAT1-OSCAR 122 or MO-122 is an American university and amateur radio satellite. [3]
On 4 July 2024, MESAT 1 was launched on a Firefly Alpha launch vehicle from Vandenberg Space Force Base in California, United States. The amateur radio transponder became operational on 20 September 2024. On 2 October 2024, the OSCAR Numbers Coordinator assigned the designation MESAT1-OSCAR-122 or MO-122 to AMSAT-NA.
MESAT 1, developed by the University of Maine, carries three experimental payloads for university research, a transmitter for commercial Globalstar, and a linear transponder provided by AMSAT for use by amateur radio operators worldwide.
The three university experiments are:
| Frequencies [4] | |
