Abstract:
Planck is an ESA mission launched in May 2009, which is mapping the microwave sky in nine frequencies and accurately measuring the anisotropies of the Cosmic Microwave Background (CMB) with its complement of two instruments (HFI and LFI), covering respectively the far infrared and the radio domains. The operations and data processing of the Planck instruments are carried out by Data Processing Centers, one for each instrument. The DPCs need to support both a day-by-day quasi-real-time calibration workflow and high-throughput pipelines for a high-volume data flow. The LFI DPC has been designed to be a centralized facility built by geographically distributed institutions, in a funding scenario based on multiple funding agencies and, in most cases, on a fixed budget in the presence of launch delays. A strategy for managing effectively the distributed and collaborative software development and maintenance has been developed, based on the use of open source and off-the-shelf software, and on the reuse of systems developed ad-hoc for other missions. Product and quality assurance has been supported throughout development, integration and testing. The effectiveness of the design choices has been proven by the readiness of the system at launch time and by the extremely smooth operations phase.
