ODIN

When developing the Auto Correlation Spectrometer, or the ACS, for the Swedish Odin Satellite Project, Omnisys was contracted by the Swedish Space Corporation to design and test two ASIC designs; one Correlator Chip, or CC, and one Analog to Digital Converter, or ADC.

Omnisys designed and manufactured the frequency agile Local Oscillator system, or LO, tuneable between 460-550 GHz. During the project Omnisys also developed the instrument control system, a digital autocorrelation spectrometer and a low filterbank spectrometer.

KEY FEATURES

The Odin satellite was launched in February 2001 having a nominal life time of two years. However, because of its scientific results and its technical performance, the mission was significantly extended and it is still in operation.

  • Frequency agile LO-system tuneable 460-550 GHz, with low phase noise.
  • Instrument Control System, i.e. the instrument computer.
  • Digital autocorrelation spectrometer.
  • Filterbank spectrometer, or low power filter bank.

MAIN APPLICATION FIELDS

Local oscillators are used in the superheterodyne receiver, meaning the radio receiver circuit. It is used to generate a signal normally for the purpose of converting a signal of interest to a different frequency using a mixer.

  • Astronomy: Odin is used in the study of star formation. Since October 2013 Odin has been used to study the comet ISON, looking for water vapor after the comet has passed the sun.
  • Aeronomy: studying the ozone layer depletion and effects of global warming.
