Module: mappingInstrument

Executive Summary

This module receives a vector of accessMsgPayloads and outputs a vector of DataNodeUsageMsgPayloads for each accessible point. This module is meant to keep track of which points have been imaged, and which have not, passing the output messages to a Module: partitionedStorageUnit module.

Module Assumptions and Limitations

This module assumes a single baudRate for all mapping points. This module provides a zero baudRate for points that are not accessible.

Message Connection Descriptions

The following table lists all the module input and output messages. The module msg connection 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.

Module I/O Messages

Msg Variable Name	Msg Type	Description
accessInMsgs	AccessMsgPayload	vector of ground location input access messages
dataNodeOutMsgs	DataNodeUsageMsgPayload	vector of data node output messages

User Guide

To use this module, the user must first instantiate the module

mapInstrument = mappingInstrument.mappingInstrument()
mapInstrument.ModelTag = "mapInstrument"

The user must then set the nodeBaudRate, in bits/second, within the module. This is a required parameter.

mapInstrument.nodeBaudRate = 1

The mapping points and names should then be added to the module one at a time. The access message is the accessMsg associated with the point. The pointName is the name of the point.

mapInstrument.addMappingPoint(accessMsg, pointName)

Finally, logs for every mapping point can be created as follows. In this example, N = 1:

dataLogs = []
for idx in range(0, N):
    dataLogs.append(mapInstrument.dataNodeOutMsgs[idx].recorder())
    scSim.AddModelToTask(simTaskName, dataLogs[idx])

class MappingInstrument : public SysModel

#include <mappingInstrument.h>

This module receives a vector of accessMsgPayloads and outputs a vector of DataNodeUsageMsgPayloads for each accessible point.

Public Functions

MappingInstrument()

This is the constructor for the module class. It sets default variable values and initializes the various parts of the model

~MappingInstrument()

Module Destructor

void Reset(uint64_t CurrentSimNanos)

This method is used to reset the module. The nodeBaudRate is checked for a non-zero value.

Parameters:

CurrentSimNanos –

Returns:

void

void UpdateState(uint64_t CurrentSimNanos)

This method updates the state by reading messages, calling computeDataStatus, and writing messages

Parameters:

CurrentSimNanos –

Returns:

void

void addMappingPoint(Message<AccessMsgPayload> *tmpAccessMsg, std::string dataName)

connects accessMsgPayload to instrument

Adds a mapping point (access message and name) to the module

Returns:

void
