1. A system for receiving signals to determine a position of an object, comprising:
- a detector arrangement configured to detect at least one continuous carrier ultrasonic waveform having data modulated thereon and a synchronization signal emitted by the object, the detector arrangement comprising;
at least a first acoustic sensor and a second acoustic sensor each configured to receive a version of the at least one continuous carrier ultrasonic waveform; and
a synchronization signal sensor configured to receive the synchronization signal; and
a computing device configured to;
decode the received versions of the continuous carrier ultrasonic waveform and the synchronization signal to measure a time delay between each of the versions of the received continuous carrier ultrasonic waveform and the received synchronization signal;
convert the measured time delays to at least a first distance and a second distance; and
triangulate the first distance and the second distance to determine the position.
