Astronomers use the 1612 MHz OH spectral line emission as a unique window on galactic dynamics and the properties of evolved stars. In recent years, experiments using this OH line have become more difficult because of interference from the GLONASS satellite system. In this paper we demonstrate that the C/A component of the GLONASS signal can be removed using a parametric estimation/subtraction technique that exploits known properties of the modulation and requires no additional antennas.

Mitigating the Impact of GNSS Signals in the Radio Astronomy Band 1610.6-1613.8 MHz
The band 1610.6-1613.8 MHz is used by the radio astronomy (RA) community in order to study the spectral line of the Hydroxyl (OH) radical transitions. This radical is considered to be one of the most
