SatMe

Name: SatMe
Author: Olivier

Amateur radio satellite tracking on Android and on the PC — passes, pointing, Doppler, logbook. Free, no account, no ads, free software.

The project on GitHub Google Play Documentation (wiki, in French)

SatMe

In your pocket to operate anywhere: next passes, compass and sky, Doppler-corrected frequencies, logbook.

SatMe-PC

The whole station in a browser: rig over CAT, rotator, SDR, SSTV, QO-100, pass journal and a full-screen dashboard for the club's stand. It is what publishes the SSTV pictures and sheets on this site.

SatMe-Node

A Raspberry Pi at the foot of the tower, driven by the PC over the network. The same engine everywhere.

This site's satellite tools are SatMe-PC's own, running in your browser: Orbits, Sked, Passes, Sky.

On the PC

SatMe-PC in demo mode: the Tracking tab with the globe, the fictitious station QF4DMO, a simulated IC-9700 and rotator — **Tracking.** Next passes, the tracked satellite on the globe, Doppler frequencies, polarisation and transmit — here in demo mode (a fictitious station).

Orbits full screen, Cartoon theme: the globe with the ISS and its orbit, the time, the Sun and the Moon, the next passes — **Orbits and its dashboard.** The Earth in 3D with the satellites, their footprints and orbits; full screen, a wall display for the club.

The Journal's editor on a session of four ISS passes, in 16:9 — **The Journal.** A small video editor: a pass or a session, the SSTV picture and overlays placed with the mouse, MP4 export.

Tracking tab on SO-50: the Polarisation panel in AUTO after an H versus V probe — **Antenna polarisation.** A USB ESP32 box switches V, H or circular at AOS, and SatMe learns which works best.

QO-100 cockpit on the SDR's test generator: waterfall, band plan and Transmit panel — **QO-100 narrowband.** Waterfall, AMSAT-DL band plan, transmit with the ADALM-PLUTO or the IC-9700 and a converter.

Showcase theme: a card announces that AO-91 passes over the station in 30 minutes — **Showcase.** For a club's stand: “AO-91 passes over us in 30 minutes, come and listen”.

On the phone

An RS-44 pass: compass, elevation, Doppler-corrected RX and TX frequencies — **A pass** and its Doppler.

Preparing any pass — **Prepare** any pass.

Pass journal: the sky and an SSTV picture coming in — **The journal**: the sky, an SSTV picture coming in.

The screenshots show the apps as they are, in French.

One station, three SatMe

The three SatMe: SatMe on the phone, SatMe-PC on a PC or a Raspberry Pi, SatMe-Node at the foot of the tower; the phone joins the PC with a QR code; the same engine everywhere
