Module: dvAttEffect

This module implements a DV attitude effector management algorithm. This algorithm is used to control both the RCS and DV thrusters when executing a trajectory adjustment.

Functions

void SelfInit_dvAttEffect(dvAttEffectConfig *configData, int64_t moduleID)

This method initializes the configData for the sun safe ACS control. 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 sun safe control

  • moduleID: The ID associated with the configData

void CrossInit_dvAttEffect(dvAttEffectConfig *configData, int64_t moduleID)

This method performs the second stage of initialization for the sun safe ACS 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 sun safe ACS control

  • moduleID: The ID associated with the configData

void Update_dvAttEffect(dvAttEffectConfig *configData, uint64_t callTime, int64_t moduleID)

This method takes the estimated body-observed sun vector and computes the current attitude/attitude rate errors to pass on to control.

Return

void

Parameters

  • configData: The configuration data associated with the sun safe ACS control

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

  • moduleID: The ID associated with the configData
