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

Various transmitters here.

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