New ETRS89 coordinates for AGRS.NL
• Antenna change (APEL)• 2014 exepcted: EIJS, IJMU, TERS, VLIS
• New station (KOS1)• 2014 expected: DLF1, AMEL, TXE2
• Tilting station: TERSLocal time series GNSS time series (ETRF2000)
• Strategy to deal with above coordinate changes: Helmert transformation to epoch 2010.5
