CCS Ultra Short Baseline USBL Underwater Positioning System Cost-effective
1 . Ultra-short Baseline Underwater Acoustic Positioning System (USBL)
ITrack UB Series Ultrashort Baseline Underwater Acoustic Positioning System (USBL) is based on underwater acoustic broadband spread spectrum technology and high-precision time synchronization technology, which significantly improves the resistance of multipath interference and hull noise.
2 . Long Baseline Underwater Acoustic Positioning System (LBL)
ITrack LB series LBL system uses transponder arrays placed on the seabed to locate the target, and uses spherical intersection to achieve high-precision positioning of the target. ITrack LB 8000 is newly designed LBL based on underwater acoustic broadband spread- spectrum technology.

Broadband Spread Spectrum Signal Processing Technology
It has good anti-noise and frequency selective fading ability, strong multi-path suppression ability and low bit error rate. In the long-distance positioning and communication, it can still maintain good performance. The networking mode between the devices is flexible and easy to expand.
Code Division Multiple Access (CDMA) technology simplifies the whole system planning and effectively improves the spectrum utilization because of its frequency reuse characteristics. It realizes the simultaneous location of grouping and multi-user.
Low Power Consumption and High Reliability
The system has compact structure, light design and mature hardware design, which ensures that the system runs steadily for a long time in limited space.
Multiple working modes
Ultra-short baseline system also has complete long baseline function. In actual operation, the hybrid baseline mode combining ultra-short baseline and long baseline can be used, taking into account both real-time and accuracy.
Compatible with a variety of peripheral sensors
Ultra-short baseline system has the function of attitude compensation, which can correct and compensate the measurement deviation caused by the attitude change of the acoustic array installation platform. Support mainstream attitude sensor, inertial navigation system, GNSS system, sound velocity profiler.
Using low power technology, it can stand by and work underwater for a long time. It supports active positioning (beacon mode) and passive positioning (response mode). Compatible with ultra-short baseline and long baseline modes.
Underwater positioning software
The underwater positioning software independently developed by China Haida, based on Windows operating system, has complete acoustic positioning (ultra-short baseline, long baseline, mixed baseline) and display functions, and can be customized according to customer needs.
