G-TeCS (gee-teks) is the Telescope Control System for the GOTO observatory.

Organisation

The gtecs Python package is split across multiple GitHub repositories:

• gtecs-common (https://github.com/GOTO-OBS/gtecs-common) - common functions and utilities that are used by other G-TeCS modules.
• gtecs-control (https://github.com/GOTO-OBS/gtecs-control) - functions and scripts for telescope hardware control and autonomous observing.
• gtecs-obs (https://github.com/GOTO-OBS/gtecs-obs) - functions and scripts relating to organising and scheduling observations.
• gtecs-alert (https://github.com/GOTO-OBS/gtecs-alert) - functions and scripts for receiving and processing transient astronomical events.
• gtecs-simulations (https://github.com/GOTO-OBS/gtecs-simulations) - functions and scripts for simulating follow-up observations with GOTO.

Prior to the 2021 reorganisation gtecs-control, gtecs-obs and gtecs-alert were called G-TeCS, ObsDB and GOTO-alert respectively.

There are also two related repositories that are used by G-TeCS but are nonetheless stand-alone packages:

• goto-tile (https://github.com/GOTO-OBS/goto-tile) - functions for generating sky grids and processing transient event skymaps.
  • Eventually this package is planned to be made usable by any telescope project, and therefore will probably be renamed.
• fliapi (https://github.com/GOTO-OBS/fli-api) - a Cython package for interfacing with FLI cameras and other hardware.
