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 currently eclipses every orbit and should usually reset to Mode B (432 MHz uplink / 145 MHz downlink). Excessive power, especially CW, may “flip” the satellite into Mode A (145 MHz uplink / 29MHz downlink) until the next eclipse.

To check or report the satellite’s current mode, please see the AMSAT Live OSCAR Satellite Status Page at Please limit your uplink power to no more than 100 watts ERP.


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), and the Virginia Tech Camera. The University of Iowa’s High Energy Radiation CubeSat Instrument’s (HERCI) mission is complete. 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 Wednesday UTC (local Tuesday 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.

HuskySat-OSCAR 107

HO-107’s V/u linear transponder is continuously available for use by amateur stations.
