+## Interesting satellites
+
+[Data gathered from here](https://amsat.org)
+
+### FM Repeaters
+
+* [ ] ISS
+
+* [ ] SO-50
+  * SO-50 carries several experiments, including a mode J FM amateur  repeater experiment operating on 145.850 MHz uplink and 436.795 MHz  downlink. The repeater is available to amateurs worldwide as power  permits, using a 67.0 Hertz PL tone on the uplink, for on-demand  activation. SO-50 also has a 10 minute timer that must be armed before  use. Transmit a 2 second carrier with a PL tone of 74.4 to arm the  timer.
+* [ ] AO-91/92
+* [ ] EO-80
+  *  FM Voice Repeater
+    * 435.080 MHz 210.7 HZ PL Tone Uplink
+    * 145.840 MHz Downlink (also 9k6 FSK data)
+  * 145.880 MHz 1k2 BPSK or CW Telemetry
+
+### Telemetry

+    * 437.465 (FM AX25)
+  * Uplink
+    * 144 MHZ (AX25 command only)
+
+* [ ] ShindaiSat
+  * [Info here](https://www.amsat.org/beaconclosed-satellites/shindaisat-ginrei/)
+  * Downlink:
+    * 437.485 (X.251k2 AFSK)
+  * Downlink:
+    *  437.305 (CW Beacon)
+
+* [ ] 50SAT
+  * [Info](https://www.amsat.org/50sat-mo-76/)
+  * 437.505 MHz
+  * Modes
+    * FM slow Morse callsign beacon
+    * FM fast Morse telemetry
+    * FSK RTTY telemetry
+    * 1kbps data

+## Quickstart 
+
+
+
+### Different types of orbit
+
+* LEO 
+  * Low Earth Orbit (160-2000km) -> A couple of minutes
+* MEO 
+  * Medium -""-(2000-35785 km) -> GPS
+* GEO 
+  * Geostationary orbit (above) -> Seems stationary but is actually moving with us
+
+
+
+### Satellite types
+
+* FM Repeaters  
+  * uplink on one band and downlink on another, so most optimally you need two antennas
+  * SO-50, AO-91, AO-92
+* Linear transponders - Usually SSB and CW
+  * Transmit LSB and receive USB
+  * OSCAR-7, FO-29, AO-73
+* Digital relay
+  * Like BBS
+  * FalconSAT-3
+
+### Doppler shift
+
+* Upward shift when approaching
+* Downward shift when departing
+
+
+
+### Terminology
+
+| Abbreviation/Term             | Translation                                                  |
+| ----------------------------- | ------------------------------------------------------------ |
+| AOS (Acquisition of Signal)   | Time that a satellite rises above the horizon                |
+| TCA(Time of closest apporach) | Time when the satellite is closest and Doppler shift is zero. Maximum elevation. |
+| LOS(Loss of signal)           | When satellite is no longer reachable                        |
+| Footprint                     | Ground area - coverage                                       |
+| Uplink                        | Earth to Space                                               |
+| Downlink                      | Space to Earth                                               |
