‘SMIDS’ Ship’s Movement Information Display System

Navigating or manoeuvring in strong winds or currents and in confined waters requires great skill. This also places severe demands on masters and pilots. Reliable and accurate data on ship movement is essential to maximise safety. SMIDS can reduce the risk of structural damage to ship and shore infrastructure. And what’s more, it minimises the threat of accidental pollution.

The AMI Marine SMIDS is a highly reliable, low-cost alternative to the Doppler systems found on many vessels.

How does it work?

‘SMIDS’ uses the data received from GPS and GLONASS satellites. It accurately measures the vessel’s movement relative to the ground.

Accurate to 0.01knots

Highly sensitive, SMIDS will detect and display vessel movement instantly often before it is visibly apparent. Consequently, ensuring vessel movement is precisely controlled. Therefore, corrective action can be taken at the earliest opportunity.

It is the perfect solution for large vessels. Those where bridge visibility is restricted, lightering, dredging and for ships that frequently manoeuvre without tugs in adverse conditions.


The system is particularly valuable in difficult docking situations. Also, the doppler system would struggle to hold its accuracy in poor weather conditions due to pitch and roll issues, sea state, cavitation and seabed disturbance. These can cause Doppler systems to report inaccurate readings.

SMIDS is a first-fit system for many new vessel-build projects in some of the most reputable shipyards around the world.

The SMIDS system is particularly suited to:

  • VLCC
  • LNG
  • Dredgers
  • Oil Tankers
  • Passenger Liners
  • Container Carriers
  • other large vessels
