// ORBITAL LOGISTICS AND PROPULSION TERM
Pointing
This refers to the precise orientation of a spacecraft or its instruments in a specific direction. It's critical for tasks like aiming antennas for communication or cameras for observation.
TECHNICAL DEFINITION
The precise control of a spacecraft's attitude (orientation) to direct its sensors, antennas, or thrusters towards a specific target (e.g., Earth, another satellite, celestial body) or along a desired vector, critical for data collection, communication, or propulsion.
BACKGROUND
Skyroot Aerospace Private Limited is an Indian private aerospace manufacturer and commercial launch service provider headquartered in Hyderabad, Telangana. The company was founded by two former ISRO scientists, Pawan Kumar Chandana, and Naga Bharath Daka.
