Swarm Charlie: Gap in EFI data on 07 August 2018

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.

Swarm Alpha: L1B ASM data gap from 24 to 26 July 2018

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.

Unexpected Swarm A GPS receiver reboot on 26 July 2018

31 July 2018

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.

ESA's unexpected fleet of space weather monitors

29 June 2018

A team of researchers, supported under ESA's Basic Activities, has recently investigated a resourceful new method of monitoring space weather. They utilised the data from the Swarm and GOCE Earth Explorer missions, and from LISA Pathfinder to investigate whether platform magnetometer data could also be used for space weather diagnostics.

 

Swarm satellite thermo-optical properties and external geometry published

22 June 2018

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.

Swarm data access simplified

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.

Earth Observation data distribution services improvement

14 June 2018

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.

Swarm Alpha: VFM data gap from 02 to 03 June 2018

05 June 2018

Due to an anomaly that occurred on the VFM (Vector Field Magnetometer) on board Swarm Alpha, the VFM science data (at 50 Hz rate) was not received from 02 June 2018 at 09:52 UTC to 03 June 2018 at 09:14:34 UTC.

Swarm Charlie: Telemetry data gap on 30 May 2018

01 June 2018

On 30 May 2018 a technical issue caused a telemetry data gap in S/C C from 21:14:47 to 23:12:23 UTC.
