The Legacy receiver at Kourou (KOU1) has been repaired and is currently
providing data. We apologize for the long delay to repair it caused by a series
of failures. The back-up receiver was also faulty and the antenna had to be
repaired as well since after the receiver was fixed it was found that water was
sitting inside the antenna.
After the antenna was repaired and installed it was detected that the antenna
height contained in the station information form was wrong, being the correct
one 0.107 meters instead of 0.120. This afects the approximately six months of
data provided from the installation till the failure.
The updated station information form is included below.
