[IGSSTATION-5190] CSN1: equipment upgrade

[David Maggert]

Author: David Maggert, UNAVCO

Dear Colleagues,

On November 8th, 2012 the USGS installed a new Topcon choke ring antenna model code TPSCR.G3 at the CSU Northridge (CSN1) IGS station. This station has a JPLA radome that has been installed at the station since 1996.  Unfortunately this radome does not have the necessary calibration to continue to participate in the IGS network.  As a result, UNAVCO will no longer be forwarding this data to CDDIS or IGN.  For non-IGS use, data from this station will continue to be available at UNAVCO along with an updated site log.  

Should the IGSCB decide to keep this station, then we will send an updated site log and publish the data at CDDIS and IGN.

Maintenance and operation of this site is performed by the USGS.

Best Regards,
David Maggert
