Satellite Power Module Dashboard Simulation

Overview

The application simulates the workflow of a satellite power module. It has two payloads - an On-Board Computer (OBC) and a Camera. Each of them has a voltage and a current draw property. The fluctuating values of those are simulated by a function that evaluates every second on the server.

The Display Panel shows the current state of the battery voltage and the current draw of each payload.

The Commanding Panel has functionality for connecting and disconnecting each payload. When a payload is disconnected, it stops drawing current.

The Notification Panel shows the current alerts, if there are any. There are three types:

• Low Voltage Alert - when voltage falls below 18V
• Full Charge Alert - activated at a voltage of 30V
• High Current Alert - when current draw exceeds 3A

Tech Stack

Front-end - ReactJS, Redux, TypeScript

Back-end - NestJS, TypeScript, MongoDB

Setup

Install dependencies

$ cd ./client && npm install
$ cd ./server && npm install

Running the application

Database

You need to have MongoDB installed. A client like MongoDB Compass is needed for setting up the database.

The URI Connection string should be mongodb://localhost/satellite-power-module.

Connect to the database and after running the server, the tables will be automatically created.

Server

$ cd ./server
$ npm run start

Client

$ cd ./client
$ npm run start

Unit tests

$ cd ./server
$ npm run test
