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.

AMSAT-OSCAR 7

On or about October 9, AO-7 entered a period of full illumination that will last until approximately December 2. During this time, the satellite’s onboard timer should switch it between Mode A (145 MHz uplink / 29 MHz downlink) and Mode B (432 MHz uplink / 145 MHz downlink) every 24 hours.

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

AMSAT-OSCAR 85

On June 27, 2019, AMSAT Vice President – Operations Drew Glasbrenner, KO4MA, provided an update on the status of AO-85:

“At about 2105UTC today I disabled the auto Safe mode function on AO-85, and turned the transponder on. After verifying it would drop with inactivity, a few QSOs were made before LOS.
Currently, the battery voltage is very low and it looks like we have a cell about to give up the ghost. Please do not use the satellite while it is in eclipse, even if you hear it OK. We are not sure what will be usable if and when this cell fails completely. In the meantime, reports to -bb are welcome and helpful.”

The Data-Under-Voice (DUV) telemetry is decoded and uploaded to the Fox Data Warehouse with the Fox Telem software available on the AMSAT website: http://www.amsat.org/tlm/leaderboard.php?id=0&db=FOXDB

Stations not equipped to receive and decode the telemetry can monitor the latest reports at: http://www.amsat.org/tlm/health.php?id=1&port=

AMSAT-OSCAR 91

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

AMSAT-OSCAR 92

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 http://www.amsat.org/tlm/health.php?id=4&port=

For the next few months, we are experimenting with a new schedule and will generally enable the L band uplink for ~24 hours during a early Wednesday 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 (https://twitter.com/AMSAT), AMSAT-bb email list, and other locations in advance, or by request.

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

FalconSAT-3

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