Page 5: Introduction
1 INTRODUCTION YOUR NOTES The WASSP DRX is a ‘Black Box’ smart transceiver that interfaces to devices and sensors to make up the WASSP Multibeam Sounder System. The system can be configured to operate in various modes, typically using a wide-angle sonar transducer to profile the water column and seafloor in high resolution. -
