					<description><![CDATA[Dear TRF User: We are pleased to announce that JTRF2020, the NASA JPL contribution to ITRF2020, is ready to be released and distributed to the community. JTRF2020 has been computed with SREF (Square-root Reference frame Estimation Filter), JPL&#8217;s newly developed software for sequentially determining terrestrial reference frames based upon a square-root information filter and smoother algorithm. JTRF2020 assimilates frame inputs &#8230;<p class="read-more"> <a class="" href="https://jsgt.jpl.nasa.gov/jtrf/announcing-jtrf2020/"> <span class="screen-reader-text">Announcing JTRF2020</span> Read More »</a></p>]]></description>
