17 October 2021

No RO data from TDX due to on-board irregularities.
12 September 2021 Due to GPS flex power problems on TSX/TDX no orbit determination is possible.
5 July 2021 No orbits until 15 July due to hardware change.
1 July 2021 Due to hardware problems there are currently no orbit data avaialble.
9 June 2021 The TSX/TDX processing is running stable again.
4 June 2021 There are problems with GPS flex power on TSX/TDX since 1 June. Currently there is no orbit determination on TSX/TDX possible.
18 May 2021 GRC RO data are operational.
28 January 2021 Test bufr data for GRACE-C are available on request.
9 September 2020 No RO data expected until 14-16 September due to hardware problems.
20 September 2019 At the moment no RO data available due to orbit generation issues. Problems will be fixed at the beginning of next week.
28 May 2018 Due to the priority of GRACE-FO downlinks of TSX/TDX in Ny-Aalesund (NYA) are reduced.
23 May 2018 GRACE-FO was successful launched.
23 May 2018 The problems with the orbit generation are solved. Radio occultation status is operatinal again.
27 April 2018 Due to technical problems with the orbit generation no radio occultations available.
20 April 2018 Occultation measurements at TSX and TDX are available again.
18 April 2018 Occultation measurements at TSX and TDX are expected in the afternoon (local time) again.
16 April 2018 The occultation measurements at TSX and TDX are turned off until further notice.
