S2CR 48/78 Acoustic Modem
S2C R 48/78 Acoustic Modem
S2C R 48/78 acoustic modem provides data rate of upto 28 kbits/ sec over a range of 1000 meters. This combined with its horizontally omnidirectional beam pattern makes this modem suitable for shallow water applications. With a high operating frequency, it is suitable for operations even near noisy installations like oil rigs.
Ideal application
- Suitable for most shallow water applications
- High data rate applications
- Combined with USBL module, provides accurate and reliable positioning and tracking along with data transmission for ROVs and AUVs
- Acoustic data network
