PURPOSE Delta Differential One-Way Ranging (Delta-DOR) is a Very Long Baseline Interferometry (VLBI) technique that can be used in conjunction with Doppler and ranging data to improve spacecraft navigation by more efficiently determining spacecraft angular position in the plane of sky. It...
5.1 The significant features are typified by a discussion of the limitations of the technique. With the description and arrangement given in the following portions of this test method, the instrument will record directly the normal spectral emittance of a specimen. However, the following conditions...

This test method defines the procedure for the determination of the curing-characteristi
This test method defines the procedure for the estimation of the extent of cure of certain non-metallic materials (e.g. preimpregnated and neat resin systems, adhesives) for aerospace use. The extent of cure is estimated by Differential Scanning Calorimetry (DSC) measurements of uncured...
Diese Prüfmethode legt ein Verfahren zur Beurteilung des Vernetzungsgrades bestimmter nichtmetallischer Werkstoffe (z. B. Prepreg- und Reinharzsysteme, Klebstoffe) für die Luft- und Raumfahrt fest. Der Vernetzungsgrad wird beurteilt, indem mittels der dynamischen Differenzkalorimetri
5.1 Concepts-This guide summarizes the equipment, field procedures, and interpretation methods used for the determination of subsurface conditions due to density variations using the gravity method. Gravity measurements can be used to map major geologic features over hundreds of square miles and to...
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...
This part of ISO 14085 specifies a method for determining the resistance of a filter element to flow fatigue caused by varying flow through the filter in various stages of the filter contaminant loading process. The filter is subjected to a uniform varying flow rate for a specified number of...
This part of ISO 14085 describes a method for verifying the collapse/burst pressure rating of an aerospace hydraulic fluid power filter element. This represents the capability of a filter element to withstand a designated differential pressure in the normal (intended) direction of flow,...
SCOPE AND APPLICABILITY This Recommended Standard contains the specification for a Delta-DOR RDEF designed for applications involving Delta-DOR raw data interchange among space agencies. The format here specified can be equally used for collecting and exchanging more general open loop raw data....
This part of ISO 14085 describes two methods to measure in repeatable conditions the filtration efficiency of filter elements used in aviation and aerospace hydraulic fluid systems. It can be applied when evaluating the overall characteristics of a filter element per ISO 14085-1, or separately....
This Technical Report is intended for calculating the probability for solar energetic particle (SEP) to have an impact on materials, hardware, and biological objects. This Technical Report establishes the differential energy spectra for the (0,1/103) MeV SEP fluences and/or peak fluxes in...
