DIY Worldwide Area Station Tracker


efy tested

The proposed Worldwide Area Station tracker, powered by the NodeMCU board, makes use of LEDs and a buzzer to point real-time ISS place.

The ISS tracker interfaces with the NASA API to entry the ISS’s present location information. Storing the person’s longitude and latitude within the code, the gadget calculates the efficient distance between the ISS and the person’s location.

The system successfully signifies the ISS’s distance by using LEDs and a buzzer. A components checks if the ISS is overhead. The inexperienced LED lights up when the ISS is instantly overhead, and crimson LEDs mild up progressively because the ISS nears the person’s location.

Communication with astronauts or others within the neighborhood is feasible when the ISS passes over, assuming they’re on the radio at the moment. This communication, facilitated by the ISS’s radio repeater, requires an antenna.

The parts wanted to construct the Worldwide Area Station Tracker are listed within the invoice of supplies desk.

Required Elements
Elements Amount
NodeMCU (MOD1) 1
Purple LEDs (LED1-LED7) 7
Inexperienced LED (LED8) 1
Resistor 220Ω (R1-R8) 8
Buzzer 1

Worldwide Area Station Tracker – Circuit Diagram

The circuit diagram of the ISS tracker is proven in Fig. 2. The tracker is constructed round NodeMCU (MOD1), a inexperienced LED (LED1), seven crimson LEDs (LED2 via LED8), and eight 220-ohm resistors (R1 via R8).

Worldwide Area Station Tracker – Code

The code is ready utilizing Arduino IDE. Within the first a part of the code, the library for Wi-Fi configuration is added, after which the Wi-Fi credentials are set within the code, such because the SSID and password of the Wi-Fi community.

The server URL is ready for acquiring the placement of the ISS. In Fig. 3, the code snippet reveals the Wi-Fi credentials, whereas Fig. 4 demonstrates the loop perform buying the ISS distance.

Subsequent, the loop perform is ready as much as extract the gap of the ISS tracker and the LEDs (LED2 via LED8) glow based on the gap from the gadget location.

When the ISS comes closest to the gadget, the inexperienced LED1 begins glowing. Additionally, the buzzer sounds when the ISS comes simply above the tracker.

Building and Testing

First, choose the right port and board within the Arduino IDE and add the code into NodeMCU.

Subsequent, assemble the LEDs and resistors together with NodeMCU as per the circuit diagram proven in Fig. 2.

On powering the gadget, the LEDs will glow based on the ISS distance from the gadget.

The ISS tracker, constructed utilizing the NodeMCU platform, serves as an attractive and academic device for monitoring the Worldwide Area Station’s orbital patterns in real-time.

This gadget presents an thrilling alternative for lovers to speak with astronauts utilizing the ISS’s radio repeater throughout its passes overhead.

Implementing this tracker retains customers knowledgeable concerning the ISS’s visibility, fostering a deeper appreciation for house exploration.
