Satellite Schedules

AMSAT currently manages five operational amateur satellites. Operating schedule information provided by AMSAT Operations is listed below. This information is subject to change. See the AMSAT-BB or @AMSAT on Twitter for up-to-the-minute information.


AO-7 is available for use by amateur stations when in sunlight. Although the satellite generally powers up in Mode B when entering sunlight, it experiences mode switches to Mode A at times. Please limit your uplink power to no more than 100 watts ERP.


AO-85 is open for use with a few conditions. Please do not use the satellite while in eclipse. If the footprint of the satellite does not touch any part of the ground that is in daylight, the satellite is in eclipse. This will give us a little extra battery life, and extend the satellite’s usable life. Please also do not “kerchunk” the satellite while in eclipse. I know this has been done to increase the number of telemetry packets received, but it is no longer acceptable. Thank you for your understanding and cooperation.


AO-91’s U/v FM repeater is continuously available for use by amateur stations.


AO-92 operations are scheduled among the U/v FM repeater, L-Band Downshifter (L/v FM repeater), Virginia Tech Camera, and the University of Iowa’s High Energy Radiation CubeSat Instrument (HERCI). Please keep the uplink clear during mode changes. Current status can be found at

We will generally enable the L band uplink for ~24 hours during a early Sunday UTC (local Saturday evening) pass. When you hear a command station announce or attempt commanding, please stand by until given the all clear.

Camera passes will be announced on Twitter (, AMSAT-bb email list, and other locations in advance, or by request.

All other times the U/v repeater will be open continuously.


The FalconSAT-3 9k6 V/u digipeater and BBS are continuously available for use by amateur stations.
