• Arduino
• USB Cable
• Compatible Microcontroller (e.g., Arduino Nano)

Steps

1. 1. Download and install the official NEO-7M libraries for Arduino IDE.
2. 2. Connect the NEO-7M to the microcontroller using the following pins: VCC to 3.3V, GND to GND, TX to RX of the microcontroller.
3. 3. Upload the provided example code to the microcontroller.
4. 4. Run the code and verify the GPS position.
5. 5. Configure the desired GPS coordinates.
6. 6. Test the system in flight or during modeling.
7. 7. Check the datasheet for further specifications.
8. 8. Adjust the GPS signal sensitivity.

Example code

Serial.begin(9600); 
#include <TinyGPS++.h>
TinyGPSPlus gps;
void setup() {
  Serial.begin(9600);
}
void loop() {
  while (gps.parse(NMEA_sentence)) {
    if (gps.location.isUpdated()) {
      Serial.print("Lat:");
      Serial.print(gps.location.lat(), 6);
      Serial.print(" Lon:");
      Serial.print(gps.location.lng(), 6);
    }
  }
}
