Swarm Operational News
11 February 2019
We inform the Swarm users that on 31 January 2019 at 15:22 UTC, Swarm B experienced a SEFI (Single Event Functional Interrupt) event. As a consequence, the dump of this packet store was aborted autonomously.
With reference to the news published on 29 August 2018, we inform the Swarm users that the Swarm Bravo magnetic field data from 19 to 28 August 2018 have been generated and now can be found in the ESA ftp server.
29 January 2019
We inform the Swarm users that from 21 to 28 January 2019, the ASM (Absolute Scalar Magnetometer) instrument on board Swarm Bravo was commanded in burst mode. Thus, the magnetic field intensity derived from the ASM and stored in MAGB_LR_1B and MAGB_CA_1B products is set to zero from 21 January 2019, at 07:36 UTC to 28 January 2019 at 06:54:23 UTC.
We would like to inform Swarm data users that from 17 October 2018, at 08:24:51 UTC, the attitude information of the Star Tracker instrument on board Swarm Bravo is provided at 2 Hz rate, instead of the previous 1 Hz.
02 January 2019
Electric Field Instrument (EFI) LP and LPI data measured by Swarm Alpha are not available on 18 December 2018. The reason for this data gap is still under investigation.
02 January 2019
Due to a science packet corruption which occurred on the VFM (Vector Field Magnetometer) on board Swarm Alpha, the VFM science data (at 50 Hz rate) were not received from 18 December 2018 at around 18:13 UTC to 19 December 2018 at 16:46 UTC when the VFM was restarted. As a consequence, no L1B VFM data are available for this time window.
19 December 2018
We inform the Swarm users that an issue was registered on-board Swarm Bravo during the EFI-TII Gain Correction Map application. This issue caused a data gap in EFI data from 16 October 2018 13:33:57 UTC to 17 October 2018 08:28:17 UTC
20 November 2018
With reference to the news published on 04 May 2017, we inform the Swarm users that the Swarm Alpha MAGx_LR_1B data from 29 April to 01 May 2017 have been regenerated and now can be found in the ESA FTP server.
20 November 2018
With reference to the news published on 14 September 2017, we inform the Swarm users that the Swarm Bravo MAGx_LR_1B data from 11 to 13 September 2017 have been generated and now can be found in the ESA FTP server.
20 November 2018
With reference to the news published on 29 May 2018, we inform the Swarm users that the issue present in the STR data, caused by 1-pixel shift in STR CHU-3, has been fixed. All the Swarm Charlie Magnetic data from 07 to 25 May 2018 have been regenerated and now can be found in the ESA FTP server.
08 November 2018
We would like to inform the Swarm users that the 2 Hz TII Cross-Track data flow dataset has been extended in the ESA FTP server, including additional data during 2017 for spacecraft A, and sparse days in 2014, for A and B spacecraft.
22 October 2018
Due to an anomaly that occurred on Accelerometer on-board Swarm Alpha, the instrument was switched off from 16 October 2018 00:53:21 UTC to 17 October 2018 07:05:06 UTC.
18 September 2018
On 17 September 2018 an improved version for both L1B and L2 Cat-2 Operational Processors was transferred into operations. We are in the process of publishing the entire datasets generated with the latest processor versions (L1B and L2 Cat-2 outputs with the following Product Baseline and File Counter: ORBATT 0401; MAGNET 0505; PLASMA 0501; ACCELE 0401; IBI 0301 ; FAC 0301; TEC 0301)
29 August 2018
Due to a science packet corruption which occurred on the VFM (Vector Field Magnetometer) on board Swarm Bravo, the VFM science data (at 50 Hz rate) were not received from approximately 10:00 UTC on 19 August to 07:10 UTC on 27 August 2018 when the VFM was restarted.
16 August 2018
A gap in data acquired by the Electric Field Instrument (EFI) on the Swarm Charlie spacecraft occurred on 07 August 2018. The duration of this gap was from 14:46:31 to 14:53:12 UTC and was due to a gain map update.
06 August 2018
Due to a test performed on the ASM (Absolute Scalar Magnetometer) commanded in burst mode on board Swarm Alpha, the magnetic field intensity derived from the ASM in the MAGA_LR_1B and MAGA_CA_1B products is set to zero from 24 July 2018 at 14:44 UTC to 26 July 2018 at 07:00 UTC.
The Swarm A GPS receiver rebooted on 26 July 2018 at 05:07:02 UTC autonomously. The GPS receiver data and time synchronization were available again at 05:29:47 UTC. The satellite's orbit and attitude seem unaffected by the anomaly. While the investigation is ongoing, it seems that there is no impact on the good health of the GPS receiver.
Modelling of non-gravitational forces such as drag or solar radiation pressure requires knowledge of the thermo-optical properties and geometry of the outer surfaces of the spacecraft. These are now provided in a memorandum and can be accessed here.
21 June 2018
All validated Swarm Level 1b and Level 2 products are now freely accessible to all users via anonymous FTP or any HTTP browser.
ESA has started a process to improve the Earth Observation data distribution services, aiming at facilitating access to data and information for the end users, initially by shortening the access path and reviewing authentication and authorisation processes.
