& GROUND SPEED LOG
SMIDS replaces
"doppler sonar docking
systems" and doppler logs with a satellite based system. The
ship's speed, ground referenced, is displayed with an typical
accuracy of 0.03 knot.
SMIDS and GEOLOG meets the requirements for a ship's SPEED and DISTANCE instrument, as accepted by the USCG and an increasing number of countries.
The "head-up" display (right) shows
 | Ship's head by gyro (or by satellite!) |
| Bow transverse speed |
| Longitudinal speed |
| Stern transverse speed |
| Bow and stern satellite status |
GEOLOG: This is our name for a single-sensor installation, giving very accurate ground speed, like a single doppler log. It comes with the navigator's (horizontal) display below.
SMIDS: Ship movement information displays system. 
SMIDS & GEOLOG
GIVES YOU:
| COG, SOG and relative motion |
| Distances run |
| An off course alarm |
| Stern position, (+/-16m 2drms) |
| No, it does not use differential |
| NMEA output for radar & ecdis |
| Heading and ROT ind. KW991 |
The picture below shows the pilot on the bridge wing of the tanker SR NORTH SLOPE using SMIDS whilst docking at Benicia, California.
"VERY impressive" said
the pilot.
"SMIDS shows me what the ship is doing before my eyes can see it" said the Captain. (This appears to be the first thing Masters notice with SMIDS.)
"It looked as if the bow was moving to port, but SMIDS told me it was the stern moving to starboard" said I.
"Its OK" said the ship's Chief Sceptic!
| No tanks or gate valves |
| Retrofit using existing cables |
| No sea trials or calibration required. Speed good enough for speed trial. |
| Unaffected by turbulence, propeller wash, boundary layer. |
| TRACK RECORD. SMIDS has been in service since March 1997. |
| Can not measure water speed. |
| Bow and stern sensor enclosure 260 x 160 x 90mm plus antenna. |
| Main unit 400 x 500 x 150 electrical enclosure on bridge. |
| KW991 heading repeater. (Centre of wheelhouse) |
| KW992 SMIDS "head-up" vertical displays. Centre of wheelhouse and bridge wings |
| KW992 SMIDS horizontal "navigator's" display for chart table. |
| The display units are not suitable for permanent outside use without special precautions. |
