Digital receivers

ARCAS & HSRS spectrographs

ARCAS

ARCAS is a digital spectrometer based on a Software Defined Radio receiver configured to scan the band 45 - 450 MHz. It has been set up on October 27 2016, in parallel to the Callisto receiver already in operation. Both instruments share the same receiving antenna via a splitter.

HSRS

HSRS is a digital spectrometer based on a Software Defined Radio receiver configured to scan the band 275 - 1495 MHz. It has been set up in late July 2015. HSRS is connected to a broad-band antenna located at the focal point of the 6-m dish.

Quicklook files

Daily quicklook overview combining ARCAS, HSRS and SXR light curves from GOES are available on this website. The very last 2 hours observations from ARCAS and HSRS and selected light curves from HSRS are also available. FITS files can be requested by email to the contact person.
