1.1 This practice provides guidelines for the qualifications to accomplish the various levels of maintenance on certificated light unmanned aircraft system (UAS). In addition, it provides the content and structure of maintenance manuals for aircraft, ground control station, and data links...
This International Standard describes the effective vertical cut-off rigidities of charged particles for near-Earth space and establishes principal requirements for their calculation. In Annex A, the calculation technique is verified using a typical example. This International Standard can...
It is common practice for management information to be exchanged between space mission management and a space link service provider for the purposes of negotiating, configuring, and executing the Tracking, Telemetry, and Command (TT&C) functions and cross support transfer services that are provided...
4.1 This guide is intended to be used to assess competencies of qualified individuals who wish to become certified as a UAS Technician through a certification program. 4.2 This guide is intended to be used in concert with a certification provider's structure and materials for management, exam...
Services and stations, radionavigational aids, radio beacons, equipment, miscellaneous.
Purpose: The Observing System Data Message (OSDM) is a standard message format to be used in the exchange of optical telescope, laser ranging station, and radar (observing systems) information between Space Situational Awareness (SSA) data providers, owners/operators of observing systems,...
The present document applies to VDB ground-air digital broadcast using Differential Eight Phase Shift Keying (D8PSK) of Ground-Based Augmentation System GBAS, intended for channel increments of 25 kHz. The VDB system provides data broadcast from ground based to aircraft systems, operating in the...
This document (first level standard) is the main document among the others regarding human-life activity support systems and equipment integration in space flight. This document, along with second and third level standards, forms a complex three-level international standard entitled: Space systems...
