KW 950E Course and Data Recorder

The KW950-E is programmed to output a single line of data at certain intervals.

  • Printout on low cost printer
  • Digital heading repeater
  • Low cost replacement for “course recorders.”
  • Connects to a gyro and a GPS.
  • Highly reliable, 1000s in service.
The KW950-E is programmed to output a single line of data at certain intervals. The data is printed on a tandard low cost printer, or to a PC for recording on disk. The interval between outputs varies according to these rules, in order to minimise paper used, and to provide a good record of data.

a) One line output every 6 minutes on a 6 minute interval. (0, 6, 12 etc. 1/10th hour.) Paper usage on passage would be typically 4 pages per day.
b) An output if course changes by 2 degrees from the last output. This occurs no faster than at a 10-second interval. Paper usage during manoeuvring would be typically 3 pages per hour.
c) An output on demand by pressing the keypad AL button.

Specifications

INPUT 1

  • DC and rectified unsmoothed DC stepper, 4 to 90v.
  • 360:1 synchro up to 115v/90v. 50/60 400/500 Hz. 90X 400 Hz contactless transmitter.
  • Tracking rate = Frequency/3 deg/sec. (DC step 333 deg/sec)
  • Or: NMEA 0183 input, so both input channels are NMEA. Input 1 $HE, AG or GP, HDT,x.x,T

INPUT 2

  • NMEA 0183, GPS data or GPS and heading data.
  • These sentences provide the data required. $GPRMC or $GPGGA + $GPVTG + $GPZDA.

The system will not function as a course and data recorder without GPS input.

OUTPUT

  • 4800 baud. 8 bits. No parity. 1 stop bit. 5v CMOS RS422 and RS232 compatible.

Example: time, position, course, speed and course over ground, date.
