1715 Cursor position

[linhkienbodam]

Hi,
I connected my 1715 radar to my plotter and I got the position to my radar. I got my cuesor position on my radar too but it disappear when I move the cursor to the target. It appear N/A< 2kts at the cursor information. Please advise.
Thank you
Nick

Do you have heading? Although you have position, the radar doesn't know which way you are turned within the 360 degrees so it can determine where the target is. If it works when moving the radar must be using COG from the GPS to determine how you are turned/pointed. When dropping below 3 knots COG becomes invalid information. If you wire heading to the radar (with your existing GPS) the cursor position would work all the time.

Where I can get the heading? from the PG500 heading sensor or my GPS?

PG500 would be a good source of heading.
