<p class="MsoNormal">Dear Colleagues,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">There was a delay of about 4 hours in the submission of IGS ultra-rapid combination for GPS week 2166, dow 5, hour 12. The delay was caused by a problem in automatic integration of UT1-UTC values from the IERS Bulletin A, which stopped
the ERP combination. I have now submitted the delayed orbit and ERP products.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Please note that the UT1-UTC value for the submitted ERP file is integrated from one day before the last non-predicted value of Bulletin A, as opposed to the normal 5 day prior. This does not impact the combined orbits, nor the combined
ERP values (Xpole,Ypole, Xrate, Yrate and LOD).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Apologies for any inconvenience this delay may have caused to you.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
