OBS Framework

General - PUS Services Implementation

Telecommand Verification Service

This service is implemented in full. The telemetry packets that carry the telemetry verification information are implemented by class DC_PUSTcVerificationPacket. The mechanism for dispatchig telemetry verification packets is implemented on top of the standard event reporting mechanism provided by the OBS Framework. The framework provides a class DC_PUSEventRepository that intercepts all telecommand-related event reports. This class analyses the event report and decides whether a telemetry verification packet should be configured and dispatched.

Housekeeping And Diagnostic Data Reporting Service

This service is implemened in part as follows:

• Class DC_PUSDefineDataReporting implements the service to define new housekeeping or diagnostic data reports (subtype 1 and 2)
• Class DC_PUSClearDataReporting implements the service to clear housekeeping or diagnostic data report definitions (subtype 3 and 4)
• Class DC_PUSControlDataReporting implements the service to enable and disable housekeeping or diagnostic data report definitions (subtypes 5 to 8)
• Class DC_PUSDataReportingPacket implements the telemetry packets reporting the housekeeping or diagnostic data (subtype 25 and 26)

Memory Management Service

This service is implemened in part as follows:

• Class DC_PUSMemoryLoadOffset implements the service to load data in memory using base plus offset (subtype 1)
• Class DC_PUSMemoryLoadAbsolute implements the service to load data in memory using absolute addresses (subtype 2)
• Class DC_PUSDumpMemoryOffset implements the service to command a memory dump using base plus offset (subtype 3)
• Class DC_PUSMemoryDumpOffset implements the service to perform a memory dump using base plus offset (subtype 4)
• Class DC_PUSDumpMemoryAbsolute implements the service to command a memory dump using absolute addresses (subtype 5)
• Class DC_PUSMemoryDumpAbsolute implements the service to perform a memory dump using absolute addresses (subtype 6)

Function Management Service

This service is implemened in full. The telecommand concept implemented by the OBS Framework makes support for this service easy and natural since telecommand packets are translated into telecommand components (instances of class Telecommand) that can be executed by some external agent. Class PUSFunctionManagement is provided to define the type and subtype for this PUS service.
