Status of the EGSE updating with SCOS 2000

Status of the EGSE updating with SCOS 2000

Project overview
Two on-ground EPIC Flight Spare instruments: 1 MOS camera at the Leicester University (UK) 1 PN camera at the MPE Panter facility of Munich (D) Both instruments are operated through the same Electrical Ground Support Equipment (EGSE) which was used for AIV tests before satellite integration.

Status of the EGSE updating with SCOS 2000

Activity proposed by Tony in 2005: to replace (part of) the current EGSE with an equipment running SCOS 2000, in order to fully reproduce on-ground the on-board status and to operate the FS chains with the same tools used by ESA.

Main problems SCOS 2000 is a data server, which has been developed to manage from the ground stations the routine operations of the flying missions


it is not designed for an EGSE application, and requires a non-standard "ad hoc" installation for the EPIC FS cameras

SCOS 2000 communication protocol is based on TC/TM "frames" instead of packets

it is necessary to foresee an "adapter" to manage the ISU, in order to convert the SCOS commands into the OBDH protocol

Open matters




health status of the FS instruments: are they still working...? (possible damage of the PN Camera Head) availability of the FS instruments: are they ready for tests...? test planning (when? what?)
