SIERA travels to India
Sonar calibration system from RTSYS is ordered by Bharat Electronics.
France-based RTSYS is to deliver two SIERA sonar calibration systems to the Indian Navy (IN), under a contract from Bharat Electronics Limited (BEL).
The value of the deal was undisclosed.
SIERA will be used to calibrate sonars used by the IN, RTSYS announced on 17 February.
As a lightweight autonomous system, SIERA is towed at variable depths from a dedicated boat, enabling it to measure the performance of both active and passive sonar systems (hull-mounted sonars, variable depth sonar, dipping sonars, sonobuoys or submarine sonars) in real-time or through delayed signal processing.
The calibration system is also used by sonar manufacturers and shipyards for performance assessments during sea acceptance tests.
One of the systems produced by BEL is the Hull Mounted Sonar Array-Next Generation (HUMSA-NG), which was initially developed for Kolkata-class destroyers but has since been deployed more widely in the IN.
According to Shephard Defence Insight, HUMSA-NG (pictured) is primarily an active sonar, but it has also enhanced passive and intercept capabilities with a detection range of 14.8km.
