3.6.16 SREM Simulation

The Gaia Spacecraft includes a Spacecraft Radiation Environmental Monitor (SREM) unit, which interfaces

to the EIU using a point-to-point RS422 link.

AVI-1958/CREATED/

The Avionics SCOE shall provide simulation of the SREM as an interface to the EIU.

AVI-1959/EIU-2294,EIU-2295/T

The SREM interface shall acquire the following differential RS422 signals from the EIU in accordance

with the requirements of: [AD06] Table 3.5-6 (SBDL Receiver Specification). TBC

• TC_sample

• TC_data

• TM_sample

• Clock

AVI-1963/EIU-2294,EIU-2295/T

The SREM interface shall provide a differential RS422 TM_data signal to the EIU in accordance with

the requirements of: [AD06] Table 3.5-5 (SBL Driver Specification). TBC

AVI-1960/EIU-2296/T

The SREM simulation shall conform to the Telecommand and Telemetry specifications defined in the

SREM ICD (Sections 6.2 and 6.3 respectively of [AD07]).

AVI-1961/CREATED/T

In open-loop test mode Telemetry data provided on the TM_data interface shall be defined initially by

input file.

AVI-1970/CREATED/T

The SREM data input file shall be a human-readable file (such as XML) in a format to be defined by

the Avionics SCOE subcontractor.

AVI-1969/CREATED/T

In open-loop test mode it shall be possible to modify individual parameters of SREM Telemetry data

by local MMI or by the CCS (Test Procedure or Command Line).

AVI-1962/CREATED/T

In closed loop test mode, the RTS shall acquire the SREM input data and define the response on the

TM_data line.
