GyROV

Need

  • Cost-effective solid state replacement of aviation mass inertia Gyroscopes used in early work class ROVs.
  • Immunity to shock and vibration during launch / recovery or road transportation.
  • Avoid the inconvenience of removal for replacement of wearing parts.
  • Bulky 400Hz power supplies create heat and occupy volume.

Challenges

  • Low cost sensors are typically simple flux gates. These have a slow response to change which prevents effective auto pilot heading hold facility.
  • Installation space is at a premium, must fit within footprint of old system
  • Ease of installation
  • Ease of use
  • Zero maintenance
  • Cost-effective

Solution

Video
  • Solid state multi sensor module, 3 axis magnetometers, two axis rate gyros and two axis accelerometer provide accurate and fast follow up response.
  • Equivalent fidelity to spinning mass technology.
  • Provides Pitch and Roll data intrinsic to sensor array
  • ROV Electronics interface card replaces the original  mass inertia gyro interface. This provides all power supplies and output connections.
  • The GyRov solid state solution fits into the footprint area of the original installation. A lightweight cable connects this directly to the interface board. No new wiring is required.
  • Electrical installation once access is gained to the ROV pod is about 5 Minutes.
  • Successfully fitted to Scorpio, Diablo, Demon, Explorer and Triton XL Work Class ROVs
