Fluxgate Heading Sensors

[MarkJohnson12345]

Any idea if the Nasa MArine heading sensor outputs NMEA??

Or does it just output its own talk for the compass.

I have looked at Nasa Marines online pages, but they don't say ye or ne.

If its NMEA it should be able to be connected to other instruments requiring heading valus.

It sends out nmea 0183 The sentence is HDG and it updates about twice a second.

I was told by a Raymarine guy at S'ton Show, that if you want radar to work properly you must have a "fast heading sensor" anyone know how fast is fast?

More than twice a second?

Just curious as don't have radar - yet /forums/images/graemlins/grin.gif

[/ QUOTE ]Yes, around 5Hz is the minimum for decent MARPA performance, and 10Hz is better.

If you invest in a heading sensor, it will only give you the results you are looking for if it is a "fast" one, 10 hz being perfect.
