A Teledyne Gavia Sonar Training Target Datasheet Teledyne Gavia Sonar Training Target Gavia AUV Module Flexible Solutions for ASW Training THE SONAR TRANSPONDER MODULE (STM), is a module for receiving and retransmitting sonar signals which allows for a standard Gavia vehicle to be configured as a Sonar Training Target (STT) for ASW training purposes. The STM consist of a flooded transducer compartment, an electronic compartment and a hydrophone that is towed behind the Gavia AUV and is capable of simulating preprogrammed target characteristics. The STM is programmable to emulate different type of realistic submarine target sizes and speeds for cost effective and re-usable ASW training capability. Assembled Gavia Vehicle in Sonar Training Target configuration Gavia Vehicle in Sonar Training Target configuration with hydrophone cable deployed PRODUCT FEATURES Features: • he Sonar Transponder Module (STM), simulates the echo responses T and acoustic signatures of a range of underwater targets • Cost effective, reusable solution for ASW training • ontrol of the STM is fully integrated into the Gavia user interface C and mission planning. • Man portable and rapidly deployed • an be operated from standard Gavia vehicles configured for C other tasks when not conducting ASW training • Wide array of additional sensors available for Gavia AUVs

A Teledyne Gavia Sonar Training Target Datasheet Sonar Training Target Autonomous Underwater Vehicles TECHNICAL SPECIFICATIONS STM Module (from Scanmatic AS, Norway) The following operational modes are supported by the STM. Echo repeat mode Weight: 10kg Frequency range: The Sonar Training Target (STT) will for the sonar sensor look as a submarine travelling with the speed of the platform and with a maximum target strength of 20 dB, which is a typical medium size submarine. Noise transmit: Store repeat When a sonar ping is detected by the STM, a pre-recorded echo is repeated. This mode gives the...
