iXBlue Gaps M5 Page 15 Frequently Asked Questions Manual Download

Page: 15 / 16

It is advised NOT to use Gaps in air. A few pings for testing is acceptable.

Gaps M5 IP Range has the same restriction as Gaps M7. We are working on resolving this

in a later firware release.

Gaps M5 and M7 (ex-G4) have the same mounting flange dimension, thus it is possible to

mount a Gaps M5 or a M7 on a same deployment mechanism.

GNSS lever arms measurement is very important to ensure good performances. The less

the lever arms are, the less the error will be. We advise to mount the GNSS antenna right

above the Gaps head when possible.

Yes, Gaps M5 and Gaps M7 use the same cable, available in 20, 50 and 95meters versions

and extendable to 190m using a repeater box.

Gaps M5 is compatible with all iXblue Medium Frequency range, Applied acoustics 1000

series and WB1 modulation (optional).

Yes, Gaps M5 have the same 3

party beacon compatibility as the Gaps M7.

Octans Nano provides reliable heading and attitude, but we recommend using Gaps M7 for

MBES applications.
