            <gco:CharacterString>GNSS-Grønland indeholder filer fra udvalgte grønlandske GNSS-stationer (GNET). Data kan anvendes til at postprocessere egne data i forhold til GNSS-stationer i Grønland. Data kan også anvendes til beregning af andre opmålings- og forskningsrelaterede opgaver.</gco:CharacterString>
         </gmd:abstract>
         <gmd:purpose>
            <gco:CharacterString>Den fundamentale geodætiske infrastruktur i Grønland udgøres af 60 permanente GNSS-stationer (Global Navigations Satellit Systemer – tidligere benævnt GPS) fordelt rundt langs Grønlands kyst. Stationerne omtales samlet som Grønlands GNSS-net eller GNET. GNSS-stationerne indsamler data fra navigationssatellitter. Disse data kan anvendes til at bestemme Grønlands bevægelse i alle planer samt til korrektion af forskellige opmålingssituationer. 

Stationerne anvendes bredt og udgør fundamentet for al anden opmåling i Grønland med GNSS. Det er ved hjælp af GNSS-stationerne, at det Grønlandske referencenet knyttes til europæiske og globale referencerammer, så entydighed i den globale og lokale positionering sikres.

Data udstilles fra alle GNET-stationerne, i forskelligt format afhængig af årstallet for den specifikke måling. Data fra den enkelte stations installation til og med 31. december 2021 er (med enkelte undtagelser) kun tilgængeligt i RINEX2-format. Data startende 1. januar 2022 og nyere findes kun i RINEX3-format. 

Spørgsmål eller anden henvendelse angående data tilgængelighed bedes rettet til KDS GNSS-team på gnss@kds.dk.

Data kan anvendes til at postprocessere forskellige GNSS-opmålinger, eksempelvis droneflyvninger, geodætiske opmålinger og andet, hvor præcision og pålidelighed i slutresultatet er højtprioriteret.</gco:CharacterString>
