# Iridium Satellite Signal Strength Monitoring This repo has the project code for the [Iridium Signal Strength Monitoring](https://nootropicdesign.com/projectlab/2019/12/27/iridium-signal-monitoring/) project. See the full project for details. There are 3 major components of this project: IridiumSignalQualityMonitor, MQTTWiFiGateway, and the NodeJS web server. ## IridiumSignalQualityMonitor Arduino code for SAMD21 microcontroller (e.g. Arduino Zero, SparkFun SAMD21 mini breakout board, etc.) The basis for this software is [this project](https://nootropicdesign.com/projectlab/2019/09/21/arduino-satellite-communication) This code asks the RockBLOCK 9603 modem for the current signal strength and writes that information over serial to an ESP8266 running the MQTTWiFiGateway firmware (see below). ### Dependencies: * [IridiumSBD library](https://github.com/mikalhart/IridiumSBD) - Arduino library for Iridium Short Data Burst messages * [Adafruit GPS library](https://github.com/adafruit/Adafruit_GPS) - Arduino GPS library for NMEA sentence parsing * [Adafruit ZeroTimer library](https://github.com/adafruit/Adafruit_ZeroTimer) - Timer library for SAMD21 * [Adafruit GFX library](https://github.com/adafruit/Adafruit-GFX-Library) - Core library for displays * [Adafruit SSD1306 library](https://github.com/adafruit/Adafruit_SSD1306) - Library for our Monochrome OLEDs based on SSD1306 drivers ## MQTTWiFiGateway Arduino code for ESP8266 that reads from serial and publishes data to MQTT. Set your MQTT server and credentials in `MQTTWiFiGateway.ino`: ``` const char* mqtt_server = "your_mqtt_server"; const char* mqtt_username = "mqtt_user"; const char* mqtt_password = "mqtt_password"; ``` ### Dependencies: * [WiFiManager](https://github.com/tzapu/WiFiManager) - WiFi Manager for ESP8266 * [PubSubClient](https://github.com/Imroy/pubsubclient) - MQTT library for ESP8266 ## NodeJS Web Server Set your MQTT server and credentials in `server.js`: ``` var options = { host: 'your_mqtt_server', port: 1883, username: 'mqtt_user', password: 'mqtt_password' } ``` Set your Cesium Ion access token in `app.js`: ``` Cesium.Ion.defaultAccessToken = 'YOUR_CESIUM_ION_ACCESS_TOKEN'; ``` To use the MapBox dark imagery like I did, you'll need a MapBox access token. Also set in `app.js`: ``` imageryProvider : new Cesium.MapboxImageryProvider({ mapId: 'mapbox.dark', accessToken: 'YOUR_MAPBOX_ACCESS_TOKEN' }) ``` Installation and startup: ``` cd webserver npm install npm start ```
