Integrating a different air module with HERE base module for RTK

ArduCopter Copter 3.5

Hi guys,

While the heading problem with the HERE GPS air module persists, I cannot rely on this module to fly my copters:

But the thing is that I have a HERE GPS base module, that I was intending to link with my HERE GPS air module to enjoy RTK navigation and geotagging of the pictures taken.

Since I cannot rely on my HERE GPS air module, due to the aforementioned issue, my question is: which GPS air module can I use to link with my HERE GPS base module in order to have RTK navigation?

Thanks in advance,

JM
