Datensatz zur Bestimmung des ILRS-Referenzpunktes am Satellite Observing System Wettzell

Abstract

Die Kombination von geodätischen Raumtechniken ist essentiell für die Bestimmung eines globalen geodätischen Referenzrahmens sowie von Erdrotationsparametern. Eine direkte Verknüpfung der unterschiedlichen Raumtechniken ist aufgrund der geringen physischen Verknüpfungen nicht ohne Zusatzinformationen sinnvoll möglich. Eine Schlüsselrolle spielen hierbei lokale Verbindungsvektoren (Local-Ties), die zwischen den geometrischen Referenzpunkten der Raumtechniken definiert sind. Diese Verbindungsvektoren lassen sich an Forschungseinrichtungen wie dem Geodätischen Observatorium Wettzell durch präzise terrestrische Vermessung bestimmen. Eine besondere Herausforderung stellen hierbei die Referenzpunkte von VLBI-Radio- und SLR-Laserteleskopen dar, da diese nicht materialisiert und direkt taktil bestimmt werden können. In diesem Beitrag wird eine indirekte Methode zur Bestimmung des geometrischen Referenzpunktes eines VLBI-Radio- bzw. SLR-Laserteleskopes vorgestellt. Das entwickelte Modell erlaubt eine automatisierte und prozessbegleitende messtechnische Erfassung aller relevanten Größen. Der neue Modellansatz erfordert darüber hinaus keine Synchronisation zwischen dem Messinstrument und dem Teleskop, sodass Messunsicherheiten minimiert werden. Eine erfolgreiche Validierung erfolgte 2018 am Satellite Observing System Wettzell, bei der die Datenerhebung vollständig automatisiert mit dem Lasertracker AT401 durchgeführt wurde, und der Referenzpunkt mit einer Unsicherheit von 50 μm bestimmt werden konnte.
