P15310: SATCOM on the Move

Systems Design

Table of Contents

This phase of the project is about fleshing out the major systems in our project. Due to the nature of our project, this phase is more about solidifying our design and general approach to the problem at hand. The main problem is that we need to provide an excellent marketing tool to Spectracom. The following notes and presentations detail our solution to tackling this problem. Our main concern during this phase was to detail out the way we would use the data from the Geo-PNT to demonstrate its accuracy and effectiveness.

The Systems Level Design Documents folder is where we keep the files associated with this phase of the project.

Functional Decomposition

To start fleshing out our system, we created a Functional Decomposition. This chart is based off of all of our customer needs and engineering requirements and uses the assumption of our customer directed Problem Definition decision of an GPS/Accelerometer aided aiming device.

To begin developing our solution, we looked at similar complete solutions and benchmarked their specifications. We decided to benchmark similiar SATCOM-on-the-move applications as we haven't yet decided on our particular aiming system and will be doing that throughout this phase and the next with some direction from our customer.

These systems are all military or industrial grade. It would be unrealistic to aim for a military standard system, but these serve as a valuable reference for what would be acceptable were this an actual SOTM system.

Concept Development

In order to further develop our solution, we took the major components of the functional decomposition and created a morphological table of solutions. After selecting some good solutions for each function, we created Pugh charts for each one and use different datum to help us determine the best possible solution to each individual problem.

Systems Architecture

After completing the analysis on the indivdual solutions, we packaged our best options together to create a few different total system solutions. This enabled us be able to provide to our customer the solution that best fit their needs given different price points. Each of the options is presented as a package, but it should be noted that each box is completely modular and the final design can be mixed and matched as seen fit. The ideal system would consist of:
Option 1

Option 1

Option 2

Option 2


At this point of the phase we decided to do some preliminary feasibility on our solutions to ensure that we could provide any of our first options to our customer. These analyses can be seen below.

Risk Assessment

At this point after completing the feasibility, we went back and updated our risk analysis. We were able to eliminate some of our risks relating to the ambiguity of our project and move forward with our design through these mitigated risks.

Systems Design Review

In order to prepare for our review, we created pre-read and notes for the presentation. Any outstanding action items can be seen on our Project Plan and Rolling Action Items List on the Planning and Execution page.
