<p>Dear sir,</p>
<p>Navigation messages from specific stations can have issues so
please read through several station files that may have the PRNs
you need or through the merged navigation file such as below, to
see if what you found is corrected/different from other receivers;</p>
<p>
<a class="moz-txt-link-freetext" href="ftp://gssc.esa.int/gnss/data/daily/2019/brdc/BRDC00IGS_R_20191610000_01D_MN.rnx.gz">ftp://gssc.esa.int/gnss/data/daily/2019/brdc/BRDC00IGS_R_20191610000_01D_MN.rnx.gz</a></p>
<p>This email list is for communications on IGS network station
issues and not for these specific questions. Please respond to
David Maggert (IGS network coordinator) and myself (IGS
Infrastructure Committee Chair) directly if further help is
needed.</p>
<p>Also please recall that the IGS is a voluntary organization
bringing together resources from hundreds of organizations on a
best effort basis and that we do not guarantee the suitability or
accuracy of the data or products for any specific purpose. <br>
</p>
<p>Finally the only EGNOS data we hold are pseudoranges in the
observation files from some stations and the navigation messages
as recorded by individual tracking stations, please let David and
I know if we can be of further assistance. <br>
</p>

Nacho
