[IGSSTATION-7291] - 2018-03-30 (04/04/2018)

Station CRO1 has had its receiver upgraded to a Javad Delta 3. The original Ashtech microZ has been removed. Data beginning from 2018-03-02 are now available.

[IGSSTATION-7253] - 2018-02-27 (08/03/2018)

I am happy to announce station CR01 (St. Croix) is now online. The station's network infrastructure had suffered damage from the hurricane last September but has now finally been repaired. A backlog of data has accumulated since September 28th 2017 which is currently being downloaded. This operation should be complete by tomorrow. Completed file downloads are available immediately. Otherwise, normal data flow operations have resumed as of today.

[IGSSTATION-7122] - 2017-09-12 (19/09/2017)

Station CRO1 on St. Croix island is currently without internet
communications due to the effects of the recent hurricane. The station
did not lose power however, and is still logging data locally.

Data has not been published since DOY249. We are exploring temporary
methods to retrieve the data until internet service is restored within
the next couple of months.
