1.1 Introduction and system familiarization
Congratulations on your purchase of SIMRAD CP42/50/52 MKII DGPS
Chartplotter - a combination of the latest GPS receiver technology and
built-in differential receiver for accurate positioning and prepared for
SDGPS, plus: detailed cartography; all in a unique slim-line design with a
10” ATFT (CP42), 14” TFT (CP50), or 15” TFT (CP52) large LCD
display in color.
The CP42/50/52 MKII chart system includes a built-in world chart for
rough planning and overview. The choice of chart system best suitable for
the CP42/50/52 MKII was carefully singled out to be the C-MAP NT+
mini cards. The optional C-MAP cards are available world-wide at your
local Simrad dealer.
The Global Positioning System is at this time and age the most common
system used for navigation and positioning all over the world. Not only for
maritime use, but also for land-based applications and aviation.
The satellite-based system has been developed and is operated by the US
Department of Defense in order to provide an accurate and reliable
service, which include a 24-hour global coverage.
The GPS system consists of approx. 24 satellites which orbit around the
Earth at an altitude of approx. 20,200 km. The satellites transmit perfectly
synchronized data. However, depending on the position, the signals will
reach the receiver at a slightly different time. By adding the measured time
difference to the known position of the satellites it is possible to calculate
the ship’s position to within a few meters.
DS42/50 Dual Station for the CP42/50/52 is available in 10” ATFT color,
14” TFT color and 15” TFT color.
How to use this manual? The manual is written for the products:
CP42, CP50 and CP52, which all share the same type of software.
From hereon, these models are referred to as: CPXX.
It is a good idea if you make yourself familiar with the key functions,
menu structure and rotation of pages (screens) described in chapter 2
before you start out, and then proceed with section 2.7 Initial start-up.
