The MBES was the 50 Khz, 126 0.5°beams, 150°aperture RESON 8160, capable (theoretically) to acquire data at 5000 m range.The sonar data were collected and recorded in realtime on HD by direct interfacing of the sonar processor P1 to the PDS-2000 software. A TSS MAHRS Motion reference Unit and gyrocompass and DGPS receiver provided the necessary real-time information for data acquisition.
The PDS-2000 was set to build a DTM at 10m spatial resolution during the acquisition of the surveyed area.
