Spacecraft telemetry not behaving as expected

[BaptisteRC]

Simulating a 500km SSO satellite, I would expect the various subsystem telemetry to vary with the solar illumination/eclipse.
Instead, I have noticed that:

• All 3 temperature endpoints have constant values (RAW_BATTERY_TEMPERATURE, RAW_EPS_TEMPERATURE, RAW_SA_TEMPERATURE)
• SA voltage is constant across multiple orbits (RAW_SA_VOLTAGE)
• BATV (RAW_BATTERY_VOLTAGE) is constantly declining, until a step change to recover then it declines again at same rate… (unrelated to the eclipse time or satellite attitude)
• ADCS telemetry data seem to vary ok at first glance (CSS_SVB vary with attitude & eclipse, Angular_Acceleration...)
  I should also mention that the CAM42 and other specific ADCS parameters confirms I am in eclipse.

Am I misunderstanding the use case of NOS3 as real time simulator?
Is there an additional configuration I have missed or do I need to develop my own software to obtain a more realistic subsystem telemetry simulation?

Thanks much!
