Is it possible to use 2-way walkie talkie to locate position?

Locating a car or person using 2-way walkie talkies without GPS involves radio signal triangulation techniques. By employing at least two receivers with directional beam antennas placed at known fixed positions, it is possible to approximate the relative position of a transmitter through angle measurements and triangulation, similar to historical aircraft navigation methods using AM radio stations and loop antennas. Distance measurement is challenging without additional data, and identifying multiple moving transmitters requires signal differentiation strategies. The use of compasses and knowledge of trigonometric laws (e.g., law of sines) aids in calculating positions. For hobby projects within a 2-mile range, setting up three antenna stations can improve accuracy. Alternatively, GPS modules like those from Laipac can transmit location data without a mobile data plan, interfacing with microcontrollers to send position information. Some walkie talkies, such as the CX312 model, integrate GPS functionality, enabling tracking without separate GPS devices or data plans.
