L band monitoring activities

During 2009 and 2010 we ran experiments with a 3-meter dish antenna located near PB8.  CNES, the French national center for spatial studies, asked us to monitor signal activities in the L band.

A specific source has been developed for that purpose, here installed at the focus point of the antenna:

3m sur AOR-W53°(c)Source bande L(a)

Two geostationary satellites emitting in the L Band were targeted for this experiment:


Inmarsat et Thuraya

The following picture shows the  frequency response of the preamplifier:
