Development of Doppler Velocity Log

Source

Source summary

Develop an indigenous Doppler Velocity Log that measures a ship's velocity from the frequency shift of reflected sound. The instrument must integrate with the ship's inertial-navigation system; the stated aim is improved navigation accuracy, not an independently demonstrated outcome.

No. 417Problem statementMobility and logistics

Indigenous development of door control unit (DCU) and gear motor for automatic operation of platform screen doors at metro stations. these platform screen doors are for passenger safety and isolates platform from track.

Develop platform-screen-door control units and geared motors for metro stations, with SIL3 safety requirements. The system must detect obstacles, adjust door timing and synchronise left/right doors to maintain the barrier between passengers and tracks.

Design of a steering console for an underwater vessel

Develop an underwater steering console integrating vehicle-motion measurements and control information. The source includes depth, speed, heading and trim, real-time serial inputs and manual, automatic and emergency modes. Detailed control implementation is omitted from this military-system overview.

No. 428Problem statementMobility and logistics

Design of electro-magnetic velocity log for navigation of underwater vessels.

Develop an electromagnetic velocity log for underwater navigation, supporting operating and simulation modes. The visible source gives a basic equipment requirement rather than a detailed user workflow or demonstrated measurement performance.
