Module: tamComm

Executive Summary

This module reads in a message of type TAMSensorBodyMsgPayload, outputs the magnetometer measurement vector in vehicle’s body coordinates tam_B to the output message tamOutMsg.

Module Assumptions and Limitations

No assumptions are made.

Message Connection Descriptions

The following table lists the module input and output messages. The module msg variable name is set by the user from python. The msg type contains a link to the message structure definition, while the description provides information on what this message is used for.

Description

tamInMsg

TAMSensorMsgPayload

TAM sensor interface input message

tamOutMsg

TAMSensorBodyMsgPayload

TAM sensor interface output message

User Guide

In order to transform the tam_S vector of TAMSensorMsgPayload from sensor to body frame, dcm_BS should be defined.


Functions

void SelfInit_tamProcessTelem(tamConfigData *configData, int64_t moduleID)

This method initializes the configData for the TAM sensor interface. It checks to ensure that the inputs are sane and then creates the output message

Parameters:
  • configData – The configuration data associated with the TAM sensor interface

  • moduleID – The ID associated with the configData

Returns:

void

void Update_tamProcessTelem(tamConfigData *configData, uint64_t callTime, int64_t moduleID)

This method takes the sensor data from the magnetometers and converts that information to the format used by the TAM nav.

Parameters:
  • configData – The configuration data associated with the TAM interface

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

  • moduleID – The ID associated with the configData

Returns:

void

void Reset_tamProcessTelem(tamConfigData *configData, uint64_t callTime, int64_t moduleID)

This method performs a complete reset of the module. Local module variables that retain time varying states between function calls are reset to their default values.

Parameters:
  • configData – The configuration data associated with the guidance module

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

  • moduleID – The ID associated with the configData

Returns:

void
