Introduction

Satellites use a variety of transmitters, frequencies, and modes (encodings). Similar equipment will produce similar observations. Satellites can have, and often do have, multiple transmitters and modes. Below are various categories of observations.

Transmitters

The SatNOGS DB API can generate the current list of transmitters.

Modes

The SatNOGS DB API can generate the current list of modes.

At the time of writing, there are 70 modes, listed below:


Example Waterfalls

Below are waterfalls depicting various modes.
