[IGSSTATION-7832] - 2020-01-09 (15/01/2020)
The IGS station POHN00FSM is currently offline. We are currently troubleshooting to determine the cause, and aim to have the site back online. RINEX and real time data will be unavailable until the issue is resolved.
[IGSSTATION-7193] - 2017-11-21 (22/11/2017)
The antenna at the IGS site POHN in Pohnpei (FSM) has failed. We are currently looking into options of getting a replacement antenna to the site. Given our current work program it is likely that this problem will not be resolved until January 2018.
In the meantime no real-time streams or RINEX products will be available.
[IGSSTATION-6793] - 2016-09-21 (21/09/2016)

Further notification will be given when the problem has been resolved.
