<div>Message:</div>
<div> </div>
<div>We have noticed a degradation in the quality of observations from the IGS site PTVL in Port Vila (VAN). This symptoms are consistent with a number of other antennas of this model that we have recently seen fail. We are currently looking into replacing
the antenna with a different model. Given our current work program this is not likely that this problem will be resolved until January 2018.</div>
<div> </div>
<div>In the mean-time to avoid erroneous data no real-time streams or RINEX products will be available. </div>
