Level

The ‘LEVEL’ option should be enabled (set to YES) when the antennas are mounted within 10

o

of each other (from the

horizontal), and not expected to exceed 10

o

during testing. With the LEVEL option enabled the GPS engines maintains

its RTK lock more efficiently and the Slip and Pitch channels are less likely to drop out.

If the expected angle between the antennas will be greater than 10

o

then the ‘LEVEL’ option should be disabled (set to

‘NO’).

Note: When the antenna separation is <2 m the RTK lock is very resilient in most conditions and scenarios when the
‘Level’ option is not enabled.
