A kinematic precise point positioning strategy was used for the GNSS analysis with a real-time GNSS satellite ephemerides (orbit and clock information). The analyzed time series of PWV was contaminated with unrealistic sharp variations that occasionally occurred. Periodic occurrence of a spiky variation with a cycle of one sidereal day, along with post-fit phase residuals averaged at each elevation and azimuth, indicated that one of the causes of the unrealistically large time variation was interference of reflected signals (multi-path). A simple quality control (QC) procedure based on the amount of PWV time variation was proposed. After the QC was applied, the retrieved PWVs had 3.4-5.4mm root mean square (RMS) differences against radiosonde observations, and 2.3-3.7mm RMS against those retrieved at nearby ground GNSS stations. The proposed QC procedure rejected more than 60 percent of retrieved PWV on research vessels and 6-11 percent on a passenger ferry. The results demonstrate the great potential of the real-time ephemerides and the necessity for careful consideration of the observation environment.</p>"}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1030003658311541249","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"30115886"},{"@type":"NRID","@value":"1000030115886"},{"@type":"CINII_AUTHOR_ID","@value":"DA10371836"},{"@type":"URI","@value":"https://ci.nii.ac.jp/author/DA10371836#entity"},{"@type":"URI","@value":"https://viaf.org/viaf/NII%7CDA10371836"},{"@type":"NRID","@value":"9000363409132"},{"@type":"NRID","@value":"9000411205474"},{"@type":"NRID","@value":"9000242878707"},{"@type":"NRID","@value":"9000253257322"},{"@type":"NRID","@value":"9000363410489"},{"@type":"NRID","@value":"9000363410745"},{"@type":"NRID","@value":"9000363408968"},{"@type":"NRID","@value":"9000363407596"},{"@type":"NRID","@value":"9000243573560"},{"@type":"NRID","@value":"9000254263683"},{"@type":"NRID","@value":"9000392819583"},{"@type":"NRID","@value":"9000392819632"},{"@type":"NRID","@value":"9000392816104"},{"@type":"NRID","@value":"9000257766972"},{"@type":"NRID","@value":"9000018892467"},{"@type":"NRID","@value":"9000016857607"},{"@type":"NRID","@value":"9000242577099"},{"@type":"NRID","@value":"9000254739606"},{"@type":"NRID","@value":"9000253255401"},{"@type":"NRID","@value":"9000392818968"},{"@type":"NRID","@value":"9000363500160"},{"@type":"NRID","@value":"9000363410481"},{"@type":"NRID","@value":"9000363405166"},{"@type":"NRID","@value":"9000363405579"},{"@type":"NRID","@value":"9000363410163"},{"@type":"NRID","@value":"9000363406880"},{"@type":"NRID","@value":"9000259864125"},{"@type":"NRID","@value":"9000356914404"},{"@type":"NRID","@value":"9000250465948"},{"@type":"NRID","@value":"9000363481387"},{"@type":"NRID","@value":"9000240187720"},{"@type":"NRID","@value":"9000257768770"},{"@type":"NRID","@value":"9000341532125"},{"@type":"NRID","@value":"9000363405171"},{"@type":"NRID","@value":"9000363404950"},{"@type":"NRID","@value":"9000363407694"},{"@type":"NRID","@value":"9000398156163"},{"@type":"NRID","@value":"9000400196020"},{"@type":"NRID","@value":"9000243883272"},{"@type":"NRID","@value":"9000253256901"},{"@type":"NRID","@value":"9000392819447"},{"@type":"NRID","@value":"9000257766664"},{"@type":"NRID","@value":"9000363405824"},{"@type":"NRID","@value":"9000363407685"},{"@type":"NRID","@value":"9000398156353"},{"@type":"NRID","@value":"9000363411514"},{"@type":"NRID","@value":"9000252829579"},{"@type":"NRID","@value":"9000000462013"},{"@type":"NRID","@value":"9000002249369"},{"@type":"NRID","@value":"9000016856831"},{"@type":"NRID","@value":"9000363407710"},{"@type":"NRID","@value":"9000237754007"},{"@type":"NRID","@value":"9000361254385"},{"@type":"NRID","@value":"9000257767011"},{"@type":"NRID","@value":"9000000042497"},{"@type":"NRID","@value":"9000009264427"},{"@type":"NRID","@value":"9000363407404"},{"@type":"NRID","@value":"9000363407168"},{"@type":"NRID","@value":"9000363407116"},{"@type":"NRID","@value":"9000363406402"},{"@type":"NRID","@value":"9000242547344"},{"@type":"NRID","@value":"9000392818026"},{"@type":"NRID","@value":"9000363405829"},{"@type":"NRID","@value":"9000363409113"},{"@type":"NRID","@value":"9000023812303"},{"@type":"NRID","@value":"9000398390125"},{"@type":"NRID","@value":"9000253257915"},{"@type":"NRID","@value":"9000363481730"},{"@type":"NRID","@value":"9000363408823"},{"@type":"NRID","@value":"9000254739701"},{"@type":"NRID","@value":"9000257917790"},{"@type":"NRID","@value":"9000363407839"},{"@type":"NRID","@value":"9000363406510"},{"@type":"NRID","@value":"9000346964371"},{"@type":"NRID","@value":"9000363409933"},{"@type":"NRID","@value":"9000363408260"},{"@type":"NRID","@value":"9000253256188"},{"@type":"NRID","@value":"9000253258808"},{"@type":"NRID","@value":"9000257767018"},{"@type":"NRID","@value":"9000283643994"},{"@type":"NRID","@value":"9000018337121"},{"@type":"NRID","@value":"9000237868740"},{"@type":"NRID","@value":"9000283593417"},{"@type":"NRID","@value":"9000363408203"},{"@type":"NRID","@value":"9000363406857"},{"@type":"NRID","@value":"9000331448889"},{"@type":"NRID","@value":"9000345283645"},{"@type":"NRID","@value":"9000257767007"},{"@type":"NRID","@value":"9000007401868"},{"@type":"NRID","@value":"9000363409411"},{"@type":"NRID","@value":"9000016857288"},{"@type":"NRID","@value":"9000363407032"},{"@type":"NRID","@value":"9000398156380"},{"@type":"NRID","@value":"9000356514885"},{"@type":"NRID","@value":"9000257768110"},{"@type":"NRID","@value":"9000363410486"},{"@type":"NRID","@value":"9000024239765"},{"@type":"NRID","@value":"9000363407526"},{"@type":"NRID","@value":"9000285477726"},{"@type":"NRID","@value":"9000403297425"},{"@type":"NRID","@value":"9000392818932"},{"@type":"NRID","@value":"9000363403338"},{"@type":"NRID","@value":"9000363403434"},{"@type":"NRID","@value":"9000363404661"},{"@type":"NRID","@value":"9000363496941"},{"@type":"NRID","@value":"9000363499160"},{"@type":"NRID","@value":"9000363401980"},{"@type":"NRID","@value":"9000363491159"},{"@type":"NRID","@va
