Issue 9041: MP-007	Dynamic telemetry check types (xtce-rtf)
Source:  (, )
Nature: Uncategorized Issue
Severity: 
Summary: 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.
