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

Experimenter’s Wednesday:

Users are invited to send Robot36 SSTV mode via the FM repeater on AO-85 during UTC Wednesdays. Please identify prior to beginning transmissions, and only send when the uplink is clear.

Stations are requested to only uplink if they have a reasonable expectation of maintaining a full-quieting signal for the duration of the image transmission. Smaller stations are encouraged to focus on receiving the images.

Please don’t send questionable or provocative images. If in doubt, pick another one. Expect all ages to be participating.


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.
