I was going to say the same thing. The rotating molten blob in the
middle makes our magnetic field way stronger. There's a feedback loop
between flowing iron passing through magnetic fields making a current
which increases magnetism which increases current, etc. I'm sure I'm
describing it poorly.
I just looked up and Mars is supposed to have localized magnetic fields
from iron deposits in the crust, but not a global magnetic field like Earth.

Does Mars have a molten core? I would think that's necessary for a
magnetic pole. In fact, the major reason Mars has very little
atmosphere is because there is no magnetic pole, or at least too
little to provide protection from the solar wind.

Assuming gyroscopic effect still works on mars? That would be one way
to keep a reference ”north”

It’s only got a 90 second flight time. So presumably it doesn’t get
very far away.
I would guess radio ranging and camera would allow it to get guidance
- similar to how missals could kick into radio station signals to
find a city back in the 60s.

I wonder how it navigates. I presume a barometric altimeter
will work there. But how would they get bearing and distance
from the ground vehicle? You could use a Doppler antenna
array to get a bearing I suppose. And maybe some kind of DME
for distance. Like to see a write up on that.
