The SAS NG SCOE is a next-generation EGSE unit that simulates the behaviour and electrical impedance of a satellite’s solar panels during AIT phases.
It reproduces the electrical behaviour of a chosen number of solar panel cells in response to requests from a PCDU’s regulators.
Current- and voltage-protected (OCP/OVP), the SAS NG delivers a constant current to each cell array independently. It can work in two modes: S3R or MPPT.
The SAS NG includes end-to-end self-test and status monitoring features when the satellite is connected.
A fast safety loop that can be triggered by an umbilical SCOE provides an extra layer of protection.
The Kallisté user interface can be used to configure, control and monitor the SCOE and can also simulate the different illumination levels in space as a result of orbital position (sun or eclipse). This interface can be used locally at the rack or remotely using an OCOE via a CCS link.
