[DG] [DG11] Heading sensor for radar overlay

[Derek - Raymarine - Moderator]

Hi Lshulan,
Thank you for your enquiry

The GA150 is an external GPS antenna which can be connected to an AXIOM PRO to improve it's GPS performance in cases where the AXIOM PRO will not be in a good position to receive reliable GPS position information - for example below decks in a Steel vessel.
So the GA150 will not provide heading data to the AXIOM, it will only provide COG data which is not the most accurate data source for radar overlay.

The best source of data for heading to give you reliable and stable heading would be either an EV1 heading sensor or an AR200 Clearcruise AR sensor. Either of these can be connected via STng to the AXIOM and will give accurate heading data to support the radar overlay feature.

I hope this helps?
Regards
Derek
