Acquisition – Software to Control Acquisition of Images for Near-Earth Object Survey Operations
The Acquisition subsystem in the Catalina Sky Survey (CSS) software suite manages the operation of telescopes and instruments to capture data on asteroids and Near-Earth Objects (NEOs). Once areas of the sky are selected for observation, Acquisition takes over, accepting the input from the Planner subsystem and coordinating the telescope, camera, and...

Planner – Planning Software for Near-Earth Object Survey Operations
The Planner subsystem in the Catalina Sky Survey (CSS) software suite is designed to help observers efficiently plan nightly asteroid and Near-Earth Object (NEO) observations. By displaying a virtual map of the sky, it helps ensure that areas previously searched, or areas unlikely to be productive, are avoided. The map shows the telescope’s current...
