Robertson/Kongsberg (continued from page 39) suiting in more precise rudder po- sitioning and extremely accurate steering. The AP-9 uses LCDs to give course information and confirm the status of various control pa- rameters. The use of touchbutton controls and the ability to take heading information from both magnetic and gyrocompass inputs makes the new unit suitable for almost any vessel. It can take heading input from most popular brands of gyrocompasses, as well as from Robertson's highly accu- rate SKR-82 gyrocompass. There is also a built-in interface for any National Marine Electron- ics Association compatible naviga- tion receiver. While designed pri- marily for larger commercial vessels and meeting all classifica- tion society requirements, the AP- 9 remains amazingly cost-effective even for large yachts. The AP-9 has a full range of re- mote controls and rudder angle in- dicators, as well as extensive self- test features. A complete second steering station is available as an option. Robertson also offers a complete line of professional steering levers (follow-up and non-follow-up) and rudder angle indicator systems. The RSG Robertson Subsea Gyro- compass provides a unique solu- tion to the problem of underwater navigation. Always a leader in technology, the Robertson product line also in- cludes the RMP Multipurpose Pilot, a high-performance, integrated po- sitioning system with joystick con- trol of rudder, thruster, and pro- peller force control. SEA-TEX Circle 55 on Reader Service Card Marine navigation information obtained by a conventional radar system can now be displayed in six different colors on the CRM-1 Color Radar Monitor from SEA-TEX of Clearwater, Fla. The 360-degree presentation is continuous and never fades from view, and the color CRT allows exceptional day- light viewing, even without a hood. The CRM-1 monitor connects to most conventional radar systems, and converts system data into a six-color display depending on the strength of the returning echo. The strongest echos are displayed in red, medium echos are yellow, weak signals come in green, and the sea surface is displayed as blue. Variable Bearing Marker (VBM) is displayed as a white dot- ted line, and Variable Range Marker (VRM) appears as a white dotted circle. The plot line is black. The plotting feature helps the operator determine relative bear- ing, course direction, and speed of moving targets around his vessel. Plotting time can be selected 15 seconds (fast) or one minute (slow). Range capability is from one- half to 64 nautical miles, depend- ing on capability of the master ra- dar. The CRM-1 can be interfaced with most conventional radars and can operate up to 50 feet away from the master radar. An audible proximity alarm warns of a target's entry into a guard zone established by the op- erator. Five zones can be selected: full 360-degree radius, 180-degree on the bow, 90-degree on the bow, 180-degree on the port, and 180- degree on the starboard. Distance of range gates can be from one- half to 64 nautical miles from the vessel. SIMRAD Circle 56 on Reader Service Card Simrad, Inc. of Seattle recently announced the immediate availa- bility of the Simrad/Taiyo TD- C338HS automatic direction finder. The unit has a fully systhesized frequency range from 200 kHz to 17.999 MHz, with 100-frequency memory and 100-channel scan- ning. Frequency is selectable via keyboard or rotary encoder, in 0.1 kHz steps. Frequency, channel, and signal strength are indicated by digital LED indicators. Bearings are dis- played automatically by a CRT in- dicator, which includes auto sense control. The TD-C338HS is one of the most advanced, state-of-the- art MF/HF automatic direction finders available. SPERRY Circle 57 on Reader Service Card Sperry Corporation of Great Neck, N.Y., one of the world's largest commercial maritime sup- pliers of navigation and guidance systems, has recently introduced a new line of vessel traffic surveil- lance (VTS) systems using a new computer-controlled console that provides full-color graphics, a touch-sensitive screen for control functions, and harbor data man- agement capabilities.
