Due to reorganizations in 1993 and 1998, the current Raymarine - at the time still under the name of the parent company - was created. In January 2001, Raymarine was formed when the division was acquired in a management buy-out backed by Hg. [4] In December 2004 the company was floated on the London Stock Exchange quadrupling Hg's investment. [5]
A Raymarine chartplotter. A chartplotter is a device used in marine navigation that integrates GPS data with an electronic navigational chart (ENC).. The chartplotter displays the ENC along with the position, heading and speed of the ship, and may display additional information from radar, automatic information systems (AIS) or other sensors.
Mini-automatic radar plotting aid (or MARPA) is a maritime radar feature for target tracking and collision avoidance. Targets must be manually selected, but are then tracked automatically, including range, bearing, target speed, target direction (course), CPA (closest point of approach), and TCPA (time of closest point of approach), safe or dangerous indication, and proximity alarm.
The APG-71 was a 1980s upgrade of the AWG-9 for use on the F-14D Tomcat.It incorporates technology and common modules developed for the APG-70 radar used in the F-15E Strike Eagle, providing significant improvements in (digital) processing speed, mode flexibility, clutter rejection, and detection range.
Radars are rarely used alone in a marine setting. A modern trend is the integration of radar with other navigation displays on a single screen, as it becomes quite distracting to look at several different screens. Therefore, displays can often overlay an electronic GPS navigation chart of ship position, and a sonar display, on the radar display ...
A typical shipboard ARPA/radar system. A marine radar with automatic radar plotting aid (ARPA) capability can create tracks using radar contacts. [1] [2] The system can calculate the tracked object's course, speed and closest point of approach [3] (CPA), thereby knowing if there is a danger of collision with the other ship or landmass.
