Ariel payload harness thermal analysis

This document describes the results of the thermal analysis of the Ariel payload harness. The evaluations reported in this Technical Note are based on assumptions derived from the present knowledge of the subsystems architecture, scientific requirements and performances expected on the basis of previous experiments and results. This is a living document that has the function to report the details of the payload cables thermal analysis. It will follow the evolution of the harness design, characteristics and performances from the thermal point of view during the Ariel payload design consolidation process. Keywords: thermal design and analysis, thermal model, spacecraft thermal control, cryogenics, exoplanets, infrared spectroscop

Planck sorption cooler system cop and cpv test plan

This document describes the test sequence and procedures of the Planck Sorption Cooler System during Commissioning (COP) and Calibration (CPV) Phases in flight. COP and CPV timelines depend on the specific subsystem considered: SCS, for example, will complete its commissioning and verification phases well before the instruments. For this reason, it will enter Routine Operations when HFI and LFI will still be in their CPV. For each in-flight SCS test or activity all needed info is reported in a table containing test name, description, constraints, duration, pass/fail criteria, operational requirements, procedures etc

Planck SCS PLM SIT at Centre Spatial Guyanais, Kourou - Quick look data analysis

Scope of this document is to provide a first quick look analysis evaluation of the functionality of the Sorption Cooler Sub-System during the SIT Test Campaign performed at Centre Spatial Guyanais (CSG), after shipment of the satellite from CSL to Kourou for the Launch Campaign. The objective of Planck PLM SIT is two fold: - to verify the correct performance of the satellite systems and the compatibility between all the integrated subsystems and instruments while operating together - to mimic some basic operating procedures which will be exercised during the different phases of the missio

Planck sorption cooler system tv/tb test procedures at csl

planned for the thermal vacuum cryogenic test campaign at CSL. Each Chapter is dedicated to a specific Phase of the Test Campaign. For each Phase in which the SCS is operated is shown a summary of: Rationale, Objective, Configuration of SVM and PLM needed, Thermal boundaries, Pass/fail criteria, Duration

Planck sorption cooler flight model 1 flight model 2 verification plan

This document is intended to contain the results of the tests of the Planck Sorption Cooler. This is comprised of the Thermal Mechanical Unit (TMU) and the LPSC flight electronics (SCE). JPL is directly responsible for testing the TMU only while providing test time for the electronics unit, for which the LPSC is responsible. The compliancy to the requirements is also reported

Planck-LFI and SCS monthly report: november 2009

This document summarises the activities performed by the LFI Instrument Operation Team in November 2009

Planck sorption cooler inflight performance prediction report

The scope of this document is to show the predictions of inflight performance of the Sorption Cooler subsystem as a consequence of analysis, the Subsystem Testing and Unit testing, and the Planck System Level Thermal Vacuum, Thermal Balance, and Cryogenic verification campaigns. These predictions will be compared with the specifications as required by ESA to demonstrate that the Sorption Cooler will operate as expected in the mission
