Systems and methods for positioning and navigating objects using phase-synchronized nonlinear oscillators are disclosed. The system includes oscillators to operate in a limit-cycle oscillatory mode. The system further includes pulse-emitting source for emitting periodic pulse sequence signal. The system further includes a processing unit to phase-lock each of oscillators to the periodic pulse sequence signal. The processing unit further extracts fundamental harmonic frequency from outputs of oscillators using bandpass filter. The processing unit further determines phase difference between outputs of oscillators based on fundamental harmonic frequency. The processing unit further computes differential time delay between oscillators based on phase difference. The processing unit further determines position of pulse-emitting source by converting time delays into relative spatial distance using predefined propagation velocity of periodic pulse sequence signal.
