A ground segment consists of all the ground-based elements of a space system used by operators and support personnel, as opposed to the space segment and user segment. [ 1 ] [ 2 ] : 1 The ground segment enables management of a spacecraft, and distribution of payload data and telemetry among interested parties on the ground.
Guidance, navigation and control (abbreviated GNC, GN&C, or G&C) is a branch of engineering dealing with the design of systems to control the movement of vehicles, especially, automobiles, ships, aircraft, and spacecraft. In many cases these functions can be performed by trained humans.
Support segment: In addition to the above-mentioned stations/centres, the system has other ground support installations involved in system operations planning and performance assessment, namely the Performance Assessment and Checkout Facility (PACF) and the Application Specific Qualification Facility (ASQF) which are operated by the EGNOS ...
NASA Systems Engeering Handbook SP-601S: "This handbook is intended to provide information on systems engineering that will be useful to NASA system engineers, especially new ones. Its primary objective is to provide a generic description of systems engineering as it should be applied througout NASA.
In 2004, the Galileo System Test Bed Version 1 (GSTB-V1) project validated the on-ground algorithms for Orbit Determination and Time Synchronisation (OD&TS). This project, led by ESA and European Satellite Navigation Industries, has provided industry with fundamental knowledge to develop the mission segment of the Galileo positioning system. [128]
The components and operation of the Cospas-Sarsat system . The system consists of a ground segment and a space segment that include: Distress radio-beacons to be activated in a life-threatening emergency; SAR signal repeaters (SARR) and SAR signal processors (SARP) aboard satellites
One of its still standing buildings now serves as a makeshift bunker for the media if a rocket explodes near the ground. Mobile Servicing System Control and Training at Saint-Hubert, Quebec, Canada. Supports Canadarm2 and "dextre" robotics operations. Space Systems/Loral Mission Control Center [5] in Palo Alto, California, US.
The Network Control Center Data System (NCCDS) is an element of the SN ground segment. [3] Collocated with the White Sands Tracking and Data Relay Satellite System, the NCCDS is the operations control facility for the network. It schedules most Space Network elements and supporting elements and provides interfaces for planning, acquisition ...
