K-Sync

Synchronization unit

K‑Sync sonar synchronisation system

K‑Sync is a sonar synchronisation system that allows operation of multiple echo sounders on the same platform without loss of data, while maximising survey speed.

Operating multiple echo sounders on the same platform introduces the risk of acoustic interference, which can reduce data quality and limit system performance.

The K-Sync system addresses this by coordinating the transmission timing of all connected systems, enabling multiple systems to operate simultaneously while maintaining data Integrity and survey efficiency.

System-level synchronization across platforms

The K-Sync system provides centralized control of transmission timing across a wide range of hydroacoustic systems.

It supports both KONGSBERG and third-party echo sounders, enabling consistent synchronization across mixed installations.

Echo sounders can be operated individually or organized into groups, allowing flexible scheduling strategies adapted to survey requirements.

Optimized transmission timing

The system continuously controls trigger timing based on system configuration and feedback signals from connected echo sounders.

This ensures that systems which may interfere acoustically are separated in time, while compatible systems can operate simultaneously.

System architecture

The K‑Sync system consists of the K‑Sync Hub, providing real-time control of synchronization and trigger signals, and the K‑Sync Harmony application, used for configuration and monitoring.

The application runs on a standard Windows-based workstation connected to the system via a network interface. The network connection is also used for optional data interfaces, such as depth input.

Customer-supplied hardware can be used, and KONGSBERG recommends the Hydrographic Workstation (HWS).

Key capabilities

  • Synchronization of up to 16 echo sounders
  • Flexible grouping and sequencing of systems
  • Support for external, fixed, or calculated trigger sources
  • Integration of feedback signals (ready-to-transmit and transmitting)
  • Signal-level diagnostics for verification and troubleshooting
  • Optional depth input for adaptive timing in varying operating conditions
