The Sonardyne ROVNav Mk4 is a highly accurate Long BaseLine (LBL) acoustic transceiver designed for positioning and navigation of subsea vehicles like ROVs and towfish. It operates using a 12-channel receiver, allowing for fast position updates and range measurements to a seabed transponder array. This system is ideal for use in deepwater operations and surveying applications, offering precise subsea positioning even at long distances, making it perfect for installation, drilling, and surveying tasks.
The ROVNav Mk4 is equipped with two remote transducers, allowing for sequential position fixing or redundancy in case of failure, ensuring continuous reliable positioning. The device can also automatically switch to transponder modein the event of power failure, enabling the subsea vehicle to be located for emergency relocation.
It is available in both Medium Frequency (MF) and Extra High Frequency (EHF) options, each offering varying range and accuracy suitable for different operational depths.
