Dear John,
Thanks for your efforts at NIUM. This station certainly has a lot of
interest from the IGS ACs on account of its strategic location. However,
I noticed that the TEQC metrics posted at
http://igscb.jpl.nasa.gov/network/site/nium.html
are quite sub-optimal, consistently for entire period since the station
resumed operations in May.
In particular, the total yield of data is much less than expected, which
seems mostly to come from a very high rate of data rejection by TEQC
(based on daily status files at CDDIS):
