Module: dvExecuteGuidance

This method takes its own internal variables and creates an output attitude command to use for burn execution. It also flags whether the burn should be happening or not.

Functions

void SelfInit_dvExecuteGuidance(dvExecuteGuidanceConfig *configData, int64_t moduleID)

This method initializes the configData for the nominal delta-V maneuver guidance. It checks to ensure that the inputs are sane and then creates the output message

Return

void

Parameters

  • configData: The configuration data associated with the delta-V maneuver guidance

  • moduleID: The ID associated with the configData

void CrossInit_dvExecuteGuidance(dvExecuteGuidanceConfig *configData, int64_t moduleID)

This method performs the second stage of initialization for the delta-V maneuver interface. It’s primary function is to link the input messages that were created elsewhere.

Return

void

Parameters

  • configData: The configuration data associated with the attitude maneuver guidance

  • moduleID: The ID associated with the configData

void Update_dvExecuteGuidance(dvExecuteGuidanceConfig *configData, uint64_t callTime, int64_t moduleID)

This method takes its own internal variables and creates an output attitude command to use for burn execution. It also flags whether the burn should be happening or not.

Return

void

Parameters

  • configData: The configuration data associated with the delta-V maneuver guidance

  • callTime: The clock time at which the function was called (nanoseconds)

  • moduleID: The ID associated with the configData
