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, @AMSAT on Twitter, and the AMSAT North America Facebook group for up-to-the-minute information.

AMSAT-OSCAR 7

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.

AMSAT-OSCAR 85

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.

AMSAT-OSCAR 91

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