XTCE12 — MP-007 Dynamic telemetry check types

Source: M. Pecchioli mauro.pecchioli@esa.i
Description : It seems that only alarms based on static definition of the allowed value ranges are
supported. Spacecraft control systems also require the support of checks against
a dynamic reference, either maintained based on commanding activities (this is
known as Status Consistency Checks in SCOS-2000) or maintained using
telemetry data (this is known as Delta checks in SCOS-2000). Provision for this
type of checks (against a 'moving' reference) shall also be made in XTCE.
Resolution: XTCE does support a form of Delta Range checks called "ChangePerSecond".
Question to RID author: "is this what you are looking for, or are you looking for
something else?" Status consistancy checks should be added to the schema. It
is believed that XTCE does support the RID authors's requirements for Delta
checks.

Add clarification for Delta checks.
