<p>Dear IGS ,</p>
<p>If you operate a Javad receiver (or know someone that does)
please note. Navigation files from the receiver could be affected
by a week roll-over problem since last Sunday (start of week
2048). Javad has now released a new version of their JPS2RIN file
conversion tool (v168) which corrects the problem and sets the
week to the correct number.</p>
<p>It is urgent that all Javad operators check this issue and
upgrade as necessary. Today we had a severe problem with
navigation files indicating the incorrect health status of the GPS
constellation from a Javad receiver using an older JPS2RIN version
and it has caused disruption to several users.<br>
</p>
<p>Please check your RINEX data file generation and if using the
JPS2RIN tool please update it to the latest version;</p>
<p>It can be downloaded from <a class="moz-txt-link-freetext"

<p>Thanks and best regards,</p>
