- Project Objective:
- Determined an initial bearing using known transmitter coordinates with on-board GPS receiver
- Adjusted the antennas azimuth and elevation automatically to obtain the highest received power
- Experimental Hardware and Software Setup:
- Arduino IDE
- NI USRP 2901 SDR
- Linear actuator drivers
- Arduino mega MCU
- LabVIEW
- Project Outcomes
- Designed an algorithm to find the direction with the highest received signal power
- Searched 100 points in 9 minutes
- Found the point with the highest power
- Designed a hardware structure to rotate the antenna and find the direction with the highest power
- Received signal from 1.38 km away with 30.44 dB loss without an amplifier
- Received signal from 1.38 km away with 30.44 dB loss without an amplifier
- Designed an algorithm to find the direction with the highest received signal power
