// ORBITAL LOGISTICS AND PROPULSION TERM
Orbit Period
The amount of time it takes for a satellite or spacecraft to complete one full revolution around a celestial body.
TECHNICAL DEFINITION
The Orbit Period (T) is the duration required for an orbiting body to complete one full revolution around its primary, determined by the semi-major axis and the gravitational parameter of the central body according to Kepler's Third Law.
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.

DEVELOPERS
Organizations developing technology related to Orbit Period.
Developer of Systems Tool Kit (STK), a physics-based software platform used extensively for mission design, orbital mechanics modeling, and satellite operations, where calculating and analyzing orbit periods is a fundamental capability.
Provides space situational awareness (SSA) and collision avoidance services by operating a global network of phased-array radars. Their core technology involves precisely determining and predicting the orbital parameters, including the period, of satellites and debris in LEO.
A company focused on satellite servicing and orbital debris removal. Their missions require advanced robotics and propulsion to rendezvous with, capture, and modify the orbits of other objects, directly manipulating their orbital periods for life extension or de-orbiting.
Operates the world's largest constellation of Earth observation satellites. Managing this fleet requires precise control and maintenance of each satellite's orbit to ensure specific revisit times and coverage, making the management of their orbital periods critical to business operations.
As the operator of the Starlink satellite constellation, SpaceX performs constant station-keeping and collision avoidance maneuvers for thousands of satellites. This large-scale operation relies on advanced autonomous systems to manage and adjust the orbit period of each satellite.
Develops and operates in-space servicing vehicles like the Mission Extension Vehicle (MEV), which docks with client satellites in geosynchronous orbit to provide propulsion and life extension. This service directly involves adjusting a satellite's orbit and synchronizing its period.
Provides launch services and manufactures the Photon satellite bus, an in-space vehicle designed for orbit raising, constellation deployment, and interplanetary missions. The Photon's primary function is to change a satellite's orbit, thereby altering its period to meet specific mission requirements.
A NASA research and development center that designs and operates robotic spacecraft for interplanetary exploration. JPL specializes in complex trajectory design and orbital mechanics, where the calculation of orbital periods around planets, moons, and the Sun is essential for mission success.
