S2CR 18/34 Acoustic Modem
S2C R 18/34 Acoustic Modem
S2C R 18/34 acoustic modem is very popular for its data rate of 14 kbit/sec and working range of 3500 meters. Its horizontally omnidirectional transducer beam pattern makes it suitable for a wide range of applications.
Ideal application
- Data transmission over medium range
- Combined with USBL module to provide accurate and reliable positioning and tracking along with data transmission for ROVs and AUVs
- Acoustic data network
