Deliver Subsea Data Where Others Fail

https://www.popotomodem.com

The Popoto Modem is a compact, inexpensive, high powered, and general purpose underwater communications device. With the included digital modulation schemes (FH, M-ary PSK), the modem will accommodate relative speed of at least ± 5 kts (± 2.5 m/sec) at the standard 26 kHz carrier frequency, and provides tracking through all header and (multiple) cargo packets.
Popoto Modem’s software is engineered to enable customization. The environment includes many common signal processing tools, such as fast correlation and convolution, FFTs, and data storage. Popoto seamlessly interfaces to external processing tools such as MATLAB or Python. Ask us about adding your own algorithms to Popoto!
