- Abstract
- The Planck Low Frequency Instrument (LFI) will observe the Cosmic Microwave
Background (CMB) by covering the frequency range 30-70 GHz in three bands. The primary instrument
data source are the temperature samples acquired by the 22 radiometers mounted on the Planck focal plane. Such samples represent the scientific data of LFI. In addition, the LFI instrument
generates the so called housekeeping data by sampling regularly the on-board sensors and
registers. The housekeeping data provides information on the overall health status of the instrument
and on the scientific data quality. The scientific and housekeeping data are collected on-board
into telemetry packets compliant with the ESA Packet Telemetry standards. They represent the
primary input to the first processing level of the LFI Data Processing Centre. In this work we show
the software systems which build the LFI Level 1. A real-time assessment system, based on the
ESA SCOS 2000 generic mission control system, has the main purpose of monitoring the housekeeping
parameters of LFI and detect possible anomalies. A telemetry handler system processes
the housekeeping and scientific telemetry of LFI, generating timelines for each acquisition chain
and each housekeeping parameter. Such timelines represent the main input to the subsequent processing
levels of the LFI DPC. A telemetry quick-look system allows the real-time visualization
of the LFI scientific and housekeeping data, by also calculating quick statistical functions and fast
Fourier transforms. The LFI Level 1 has been designed to support all the mission phases, from
the instrument ground tests and calibration to the flight operations, and developed according to the
ESA engineering standards. (literal)
