// ORBITAL LOGISTICS AND PROPULSION TERM
Pass
A period during which a spacecraft is within communication range of a ground station, allowing for data exchange and command transmission. These are scheduled windows for contact.

TECHNICAL DEFINITION
A Pass refers to the interval during which a spacecraft is visible to and can establish a communication link with a specific ground station, enabling telemetry downlink, command uplink, and tracking data exchange.
BACKGROUND
Skyroot Aerospace Private Limited is a private Indian 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.
