Guide to Probability of Failure Analysis for New Expendable Launch Vehicles. Version 1.0

Nov. 2005; 22 pp.; In English Report No.(s): PB2006-102096; No Copyright; Avail.: CASI: A03, Hardcopy 14

This document provides definitions of key terms and performance standards for new expendable launch vehicle (ELV) failure probability analyses. A performance standard permits a launch operator to continue to employ alternative, potentially innovative methodologies if the results satisfy the performance standard. Current practice at the Federal launch ranges includes multiple methodologies for determining the probability of failure for new ELVs. The Federal Aviation Administration (FAA) here presents an acceptable method, but not necessarily the only method, to demonstrate compliance with the performance standard. The method suggested here is also intended to illustrate an acceptable level of fidelity for new ELV probability of failure analyses. NTIS

Lithium-Ion Life Expectancy Verification Guidelines for Transformational Communication Satellite System (TSAT)

Hwang, W. H.; Ang, V. J.; Nov. 25, 2005; 12 pp.; In English Contract(s)/Grant(s): FA8802-04-C-0001 Report No.(s): AD-A440018; AEROSPACE-TR-2006(1455)-1; SMC-TR-06-01; No Copyright; Avail.: CASI: A03, Hardcopy

Guidelines are provided for the Transformational Communication Satellite System (TSAT) mission relative to life expectancy verification of lithium-ion cells.

Conditions and associated risks are presented to facilitate a decision to include or adopt the technology, or a decision to launch before there are sufficient data to conclusively verify life expectancy. DTIC

SpaceCAPS: Automated Mission Planning for the TechSat 21 Formation-Flying Cluster Experiment

Mohammed, John L.; Jan. 1, 2002; 5 pp.; In English; Original contains color illustrations Contract(s)/Grant(s): F29601-01-C-0035 Report No.(s): AD-A440102; No Copyright; Avail.: Defense Technical Information Center (DTIC)

This paper describes a project concerned with the development of a mission planning system to provide automated planning assistance for the Air Force TechSat 21 formation-flying satellite cluster experiment: Spacecraft Cluster Automatic Planner/Scheduler (SpaceCAPS). The project's focus is on planning and scheduling for payload management, but the system serves as a central planning system for planning and scheduling of all spacecraft functions. The paper describes some of the planning and scheduling requirements for cluster payload management, and describes a system for optimization of the mission plan for the TechSat 21 space-based radar surveillance system.
