It provides no latitude for the navigator (7)

Ross

I believe the answer is:

equator

I'm a little stuck... Click here to teach me more about this clue!

'it provides no latitude' is the definition.
The definition suggests a singular noun which matches the answer.

'for the navigator' is the wordplay.
I cannot quite understand how this works, but
'for' could be 'to' (eg both can mean 'in the opinion of') and 'to' is found in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for equator that I've seen before include "It's at zero degrees latitude" , "Circle round the globe" , "Hemisphere divider" , "Imaginary circle round the earth" , "A circle around earth's centre" .)

I've seen this clue in The Globe and Mail.
