The Umbilical Interface powers, controls and monitors the spacecraft during integration / validation through the umbilical interface. The Launch EGSE provides spacecraft control and monitoring and electrical power provision on launch pad through umbilical interface compatible with launch environment.
It is used during integration / validation phases and during launch campaign.
As a baseline, it provides :
> Multi independent output power lines (adaptable power, line per line)
> Batteries trickle charge
> Main bus conditioning and monitoring
> Overvoltage detection
> Line routing to / from other SCOE
> High Power Command (HPC)
> Standard Over Voltage and Over Current protection
It is based on COTS items (power supplies, electronic loads, I/O units, PC).
As options, it can be fitted with:
> second level over voltage / over current protection (per line, per group of lines, …) (SyCTRL Protection)
> specific sensor simulation (thermistor, cell sample, switch, …)
> full redundancy
> umbilical link tester
