An Arduino-based visualization tool for tracking and displaying the positions of DSCOVR (Deep Space Climate Observatory) and ACE (Advanced Composition Explorer) satellites in real-time. This project uses an Arduino UNO R4 WiFi board with a 2.8" TFT touchscreen display to show the satellites' positions in GSE (Geocentric Solar Ecliptic) coordinates. This is a port of the original DSCVR-ACE-VISUALIZER project to the Arduino UNO R4 WiFi board.

• Real-time visualization of DSCOVR and ACE satellite positions
• Automatic data updates every 12 hours from NASA's SSCWeb
• Interactive 2.8" TFT touchscreen display
• GSE coordinate system visualization with grid
• SEZ (Sun-Earth-Zero) angle indicators (2° and 4° circles)
• WiFi connectivity for data retrieval
• NTP time synchronization
• Detailed satellite position information display

• Arduino UNO R4 WiFi board
• 2.8" TFT Display with ILI9341 controller (I used https://www.amazon.com/dp/B01EUVJYME?ref=ppx_yo2ov_dt_b_fed_asin_title)
• microSD card module (optional)

TFT Display: DC: Pin 9 CS: Pin 10 RST: Pin 8 Touch Controller: CS: Pin 7 SD Card (optional): CS: Pin 4

The following libraries are required:

• WiFiS3
• ArduinoHttpClient
• ArduinoJson
• SD (optional)
• Arduino_GFX_Library
• XPT2046_Touchscreen
• TimeLib
• NTPClient
• TinyXML
• vector (C++ STL)

1. Install the Arduino IDE
2. Install all required libraries through the Arduino Library Manager
3. Clone this repository:

git clone https://github.com/papercircuit/DSCOVR-ACE-Visualizer-arduino.git

4. Open the .ino file in Arduino IDE
5. Update the WiFi credentials:

const char* WIFI_SSID = "<Your_SSID>";
const char* WIFI_PASSWORD = "<Your_Password>";

6. Upload the sketch to your Arduino UNO R4 WiFi

1. Power on the device
2. The display will show a loading screen while connecting to WiFi
3. Once connected, it will fetch initial satellite position data
4. The visualization will update automatically every 12 hours
5. The display shows:
   • Current positions of both satellites
   • GSE coordinate grid
   • SEZ angle indicators
   • Satellite coordinates in miles

• Blue dot: DSCOVR satellite
• Green dot: ACE satellite
• Red circle: 2° SEZ angle
• Orange circle: 4° SEZ angle
• Grid: GSE Y and Z coordinates in thousands of miles
• Current satellite positions shown with coordinates

Satellite position data is retrieved from NASA's SSCWeb service: sscweb.gsfc.nasa.gov

1. Fork the repository
2. Create your feature branch (git checkout -b feature/AmazingFeature)
3. Commit your changes (git commit -m 'Add some AmazingFeature')
4. Push to the branch (git push origin feature/AmazingFeature)
5. Open a Pull Request

• NASA SSCWeb for providing satellite position data
• Arduino community for library support
• Original concept inspired by NASA's space weather monitoring systems

• The visualization updates every 12 hours to avoid overwhelming the NASA SSCWeb service
• WiFi credentials can be configured via the touchscreen interface if SD card storage is enabled
• All positions are displayed in GSE (Geocentric Solar Ecliptic) coordinates
• Distances are in miles from Earth's center

• If the display shows "Connection Failed", check your WiFi credentials or press the reset button on the Arduino
• If satellite positions aren't updating, verify your internet connection
