OscarWatch
Know where the bird is. Know where to point. Know where to tune.
Work amateur satellites from one place. OscarWatch Tracker in the shack for the pass, live transponder status, our own TLEs, and UHM on packet.
The suite
OscarWatch Tracker is the program you run in the shack. The rest of OscarWatch backs the pass: transponder status, TLEs, and packet confirmation.
OscarWatch Tracker
Pass tracking with map, sky plot, Doppler, and optional rotator and CAT for FM cubesats and linear transponders.

OscarWatch Logbook
Log QSOs during the pass, export ADIF, and optionally push to Cloudlog. It lives in OscarWatch Tracker, not as a separate download.

View statusUHM
You Heard Me: near-real-time confirmation on packet digipeaters, so you can stop calling when the other station already copied you.
How UHM worksTLE / transponder feed
OscarWatch has its own TLE system and a distributed transponder feed, so there are no extra files to edit. New transponders appear in OscarWatch Tracker automatically.
OscarWatch Terminal
A packet terminal with UHM built in. A dedicated client for digipeater passes is on the way.
How GreenCube started OscarWatch
The pile-up on IO-117 is why UHM exists: fewer blind repeats, more real RF contacts. GreenCube itself is QRT, but that origin story is still part of OscarWatch.
