5.1 Certified reference materials (CRMs) prepared from nuclear materials are well characterized, traceable, and sufficiently homogenous and stable for their intended use. Usually they are certified using the most unbiased and precise measurement methods available, often with more than one...
5.1 Spectral analysis of soils for agricultural use is being used worldwide to obtain rapid data on soil nutrients. for the purpose of agricultural management including fertilizer application and other amendments such as pH adjustment, organic supplements, etc. Satellite, aerial, and...
1.1 This classification covers pairs of scales for classifying an aspect of the serviceability of an office facility, that is, the capability of an office facility to meet certain possible requirements for special facilities and technologies. 1.2 Each pair of scales, shown in Figs. 1-4, is for...
1.1 This guide explains how to characterize the quality of metal powder feedstock to additive manufacturing (AM) relative to the powder shape using automated static or dynamic image analysis by optical photography. This guide will describe the method(s) to measure powder shape parameters that can...
How can cognition, a concept traditionally associated with the human brain, be applied to satellite systems? For the first time, cognitive system meanings and models are applied to the uncertain environmental processes of satellite systems. The authors of this book go beyond defining...
This document recommends criteria for the control and display of communications and navigation equipment on the flight deck. The equipment includes: a Communications: Ultra high frequency (UHF), very high frequency (VHF), and high frequency (HF) radios, cabin/service interphones, public address...
Department of Defense (DoD) policy requires that satellites be protected against natural space and nuclear radiation environments as specified in MIL-STD-3053, Military Standard: Satellite Systems Natural and Nuclear Environment Standard. The types and efficacy of the protection...
1.1 This guide provides information and criteria for selection of remote sensing systems for the detection and monitoring of oil on water. 1.2 This guide applies to the remote sensing of oil-on-water involving a variety of sensing devices used alone or in combination. The sensors may be mounted on...
Global Navigation Satellite Systems (GNSS) and their associated technologies have advanced by leaps and bounds in the nine years since the first edition of this book was published. The concept of survey has changed, especially in the disciplines of geomatics and geoinformatics. This revised...
The present document covers requirements to demonstrate that radio equipment both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference. The present document applies to satellite communications Earth Stations (ES) with the following...
The present document is a specification of the lower layers and the lower layer signalling system for the two-way satellite network variants defined by ETSI TS 101 545-3 [i.16]. The present document constitutes a complete specification of the lower layers for a transparent star...
Small satellites use commercial off-the-shelf sensors and actuators for attitude determination and control (ADC) to reduce the cost. These sensors and actuators are usually not as robust as the available, more expensive, space-proven equipment. As a result, the ADC system of small...
This Technical Report describes a number of different satellite reception scenarios and how to use SCD2 here. In particular, Universal and Wideband LNB architectures for different SHF bands (Ku-, Ka- and C-Band) are taken into account.
1.1 This guidance focuses on data exchange between space operators and the U.S. Federal Aviation Administration (FAA) for Air Traffic Management (ATM) operations during FAA-licensed launches and reentries. 1.2 This guidance does not apply to licensing or regulatory purposes, nor to the tracking of...
This SAE Aerospace Information Report (AIR) presents reference information for use in preparing detailed specifications and other documents. The intent is to have a master reference document containing frequently required tabulations of information, such as the meaning of abbreviations, the spelled...
Many systems architecture optimization problems are characterized by a variable number of optimization variables. Many classical optimization algorithms are not suitable for such problems. The book presents recently developed optimization concepts that are designed to solve such problems. These new...
This document establishes the requirements for simulation of the space control system, including the objective, architecture and procedure, etc. This document is applicable to four phases of control system development, including conceptual design, detailed design, prototype and integrated system....
This Recommendation is applicable to the passive intermodulation (PIM) measurement of passive array antenna systems in mobile communication systems. This Recommendation defines the setup and test methods for antennas in low intermodulation applications that can be found in cellular mobile...
