This thesis documents the design and implementation process for the next generation of the WPI Precision Personnel Location (PPL) system hardware. The driving goal of the new hardware was to support a new method of radio frequency location developed at WPI referred to as Transactional Array Reconciliation Tomography (TART). This new method is based on a time of arrival (TOA) technique as opposed to the previous Singular Value Array Reconciliation Tomography (SART), which uses time difference of arrival (TDOA). The use of a TOA method requires additional timing information and necessitates a bidirectional (transmit and receive) multicarrier transaction. The design of the new transceiver that can function as both a mobile locator and a static reference unit is the main focus of this thesis. This redesign also addressed previous hardware issues that have been exposed through extensive use in real world testing.
