24/7 Base Station
The second base station is located on the roof of the Mineral Resources Department in Mead Road Nabua. The coordinates of this base station (Trimble DSM212L) is based on WGS84 Datum

However this station logs corrections files in ssf and rinex format together with the almanac and log of the base station. You can freely download the files to do DGPS post processing for most of the
Fiji Islands.
We try to keep this station running 24/7 and we post scheduled downtime information on the mailing list GIS-Pacnet.
Notice: This service is experimental and has no warranty what so ever. If you run a ship on to the reef do not come to complain. The service can be interrupted and terminated at any time, for short or long periods. We are using spare survey equipment which is most of the year idle. However we are interested in your feedback to know if we should make it permanent. if you also plan a survey and need to ensure that the equipment is switched on, please contact us to avoid disappointments. We accept donations to maintain permanently this service.
