Sensor Error Notification System (SENS) plays a crucial role in ensuring that the Sensor Management System (SMS) functions appropriately as the program checks if the sensors that provide information to the SMS operate optimally. The SMS functions by identifying problems that predispose the ship to insecurity, such as the failure to use Active Hull Cooling, which reduces the ship’s infrared fingerprints or loud engine, and recommends modifications to enhance security. However, the ship’s crew members are likely to receive inaccurate sensor readings without SENS. Therefore, it is crucial for the members of [CLIENT] to understand the developmental process of SENS.

Given that SENS was an original concept, the initial development step involved drawing of diagrams to present the layout of the screen in order to facilitate the creation of concept designs for a review. The primary intention was to ensure that the program displayed a significant amount of information on start-up. Such amount of information would require several sub-screens accessible from the homepage.

The second step involved designing a PowerPoint version in order to obtain more visual representations of the SENS interface. The additional PowerPoint details facilitated several design choices, including a button banner, which improved the operator's ability to maximize accessible information and banner layout, what facilitated a continuous stream of important information to the operators irrespective of the sensor being viewed.

LabVIEW programming environment was used to develop the final version of SENS. The process involved polishing the display of the finalized PowerPoint interface and executing some alterations in order to accommodate the limitations of LabVIEW. During this phase, the banner was modified to tab format with LED indicators that showed erroneous sensor although the limitations could not allow dynamic color change. Each screen displayed much data, particularly the home screen, which displayed information from all sensor sections.

SENS uses LED buttons and lights to communicate problems to the operator. When the system operates within the pre-set parameters, each light displays green or red only when the performance exceeds or falls below the threshold. The LED buttons also facilitate communication with each ship diagram. The SENS home screen enables the operator to receive sensor state message feedback with a click on each sensor indicator LED. Such message feedback may include the current values of the sensor together with the current time. In order to analyze the functionality and usability of SENS, it would be important to examine how SENS shows and monitors sensor data and error cases. It can be achieved by exploring the LabVIEW code.

The functionality of the program can be understood by analyzing the codes’ central loop structure events. The most important event is the Init event, which encloses initialization of data displays, graphs, and buttons in the SENS. The Init also plots the ship track and loads data files and pictures. The second last event is timeout, while the final event is the terminate program. The two events are responsible for shutting down the program when the operator decides to close it.

SENS is designed to display a large amount of sensor data, identify errors, and alert the operator of every problem explicitly. However, this program has some flaws. First, SENS functionality does not cover all programs since the error case demonstration is limited to one sensor. Second, SENS cannot secure connections to the real-world data streams. Moreover, the program experiences minor delays when switching between tabs.

Signature Management Systems play a crucial role in tracking military vessels output and recommending improvements in order to reduce ship operations and improve security. SENS is an integral component of SMS as it guarantees accuracy of the information transmitted to the SMS. It also ensures that the sensors are functioning optimally and correctly. The functionalities of SENS and SMS ensure safe operations and success of military vessels.
