5. Working Principle
The KONGSBERG TRX32 303088 acoustic transceiver board adopts a full closed-loop acoustic positioning workflow: receiving master control commands → multi-frequency signal transmission → underwater echo acquisition → signal conditioning and noise reduction → data decoding and computation → upload of positioning data → fault self-diagnosis and protection. It serves as the core signal interaction and computation unit of the HiPAP underwater acoustic positioning system.
During system operation, the board receives operational commands issued by the HiPAP master control system in real time and synchronously transmits multi-frequency acoustic pulse signals via 32 independent channels. The signals travel through the underwater medium, reach seabed transponders or underwater targets and are reflected to form echo signals. The board captures faint echo signals precisely, completes signal gain compensation through the pre-amplifier circuit, and then performs multi-stage filtering, waveform shaping and noise removal to strip underwater clutter and interference signals and restore pure and valid acoustic signals. Relying on the on-board high-speed computing unit, it accurately resolves key parameters such as underwater acoustic transmission time delay, phase difference and amplitude, calculates positioning data including distance and coordinates of underwater targets, and uploads the data to the system master unit in real time to realize closed-loop high-precision underwater positioning control.
While executing signal transceiving and data computation, the board continuously monitors the operating status of the 32 channels, circuit conditions, signal quality and communication link status in real time. It identifies hidden risks such as channel failure, signal abnormality, circuit fault and communication interruption, immediately locks abnormal points, uploads fault codes and triggers system alarms. Together with the master control system, it performs fault masking and fault-tolerant processing to ensure continuous, stable and high-precision operation of the underwater acoustic positioning system and prevent positioning drift, data invalidity and system shutdown.
