The Heterodyne Instrument for the Far-Infrared onboard the ESA Herschel satellite is a heterodyne spec- trometer with unprecedented frequency range, resolution and sensibility. It is composed of two spectrometers, a Local Oscillator Unit, producing the mixing signals, a Focal Plane Unit, perfoming mixing and amplification, and an Instrument Control Unit, hosting a DSP where the On Board Software (OBS) runs. The OBS coordinates the other units, manages the interface with the spacecraft and monitors the instrument status. A synthetic description of the OBS organization and functioning is presented in this paper

Abstract
The Heterodyne Instrument for the Far-Infrared onboard the ESA Herschel satellite is a heterodyne spec- trometer with unprecedented frequency range, resolution and sensibility. It is composed of two spectrometers, a Local Oscillator Unit, producing the mixing signals, a Focal Plane Unit, perfoming mixing and amplification, and an Instrument Control Unit, hosting a DSP where the On Board Software (OBS) runs. The OBS coordinates the other units, manages the interface with the spacecraft and monitors the instrument status. A synthetic description of the OBS organization and functioning is presented in this paperI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
