One machine has multiple functions
Simultaneously possessing four major functions: acoustic communication (similar to underwater modem), acoustic ranging, positioning and navigation, and acoustic release

The ART series underwater acoustic release device is a multifunctional underwater acoustic equipment independently developed by the Chinese Research Institute. It integrates acoustic communication, ranging, positioning navigation, and release and recovery, and has completely independent intellectual property rights. This series of products utilizes the principle of underwater acoustic communication to provide highly reliable acoustic remote control, data communication, positioning and navigation, as well as underwater instrument deployment and recovery services for underwater weapons, submersible marking systems, marine instruments and equipment, and underwater robots. The ART series adopts advanced signal processing technology and modular design, with strong anti-interference ability, high integration, and flexible installation, which can adapt to various complex underwater acoustic environments in shallow and deep waters.

Simultaneously possessing four major functions: acoustic communication (similar to underwater modem), acoustic ranging, positioning and navigation, and acoustic release
Hardware protection circuits, software redundancy design, and precision machining ensure long-term stable operation
Adopting adaptive digital filtering, background noise tracking, and instantaneous frequency variance detection techniques to effectively suppress multipath and noise interference
We offer four forms: integrated, two-piece, three piece, and OEM embedded, to meet the needs of different platforms
Each user has an independent address and verification code to avoid accidental triggering and ensure high security
Ultra low power MCU and DSP platform, supporting up to 48 months of standby (depending on model)

Provide remote release and recovery for underwater seismometers, electromagnetic receivers, submersible markers and other equipment
As the basic element of long baseline (LBL), short baseline (SBL), and ultra short baseline (USBL) positioning systems, or providing underwater navigation for AUVs and UUVs
Realize data transmission between underwater equipment and surface units (acoustic modem function)
Support long-term deployment tasks such as underwater structure observation, environmental monitoring, and resource exploration
Assist in the deployment and recovery of underwater node instruments
Can be combined with the Beidou system to achieve underwater target positioning
