RedNODE is an acoustic navigation receiver. Like the GNSS receiver, it calculates its absolute geographic position, depth, and temperature.
Operating the RedNODE in many ways similar to the work with GPS/GLONASS receiver, but instead of GNSS satellites, it needs four RedBASE sonobuoys deployed that allow an unlimited number of RedNODE receivers to function at the same time and at the same place.
Small size, low power consumption and ease of use make RedNODE an ideal solution for mini-ROVs and AUVs and for work-class ROVs.
