if noise level is 80 dB ref µPa: max range is 2 300 m (example of a vessel
manoeuvring, Gaps at a reasonable distance from the thrusters)

if noise level is 90 dB ref µPa: max range is 1 300 m (example of a vessel
manoeuvring, Gaps very closed from the thrusters)
Gaps M5
Gaps M5 maximum range is 995 m, making it free-of-export restrictions.
Try to use lever arms 10x as accurate as your measurement. For example, within 10cm for
a 1 m accurate GPS. This will make sure your lever arms will not affect the performance of
your system.
The Gaps systems cable can be 95m maximum long because of the limitation of Cat 5
Ethernet maximum length. If longer distances are required between Gaps head and Gaps
box, it is possible to connect 2 x 95 m cables through a repeater box (total length is then
190 m).
The reference point of the USBL is the SUBCON connector, on top of Gaps M7 and M5
heads.
Because of its specific antenna composed of 4 hydrophones, that form a tetrahedron. This
is a 3D antenna than enables to position a beacon with good accuracy on 3 axis (X, Y and
Z). Gaps M7 and M5 have an aperture of 200° which means we can track a beacon less
deep than the antenna.
Almost all navigation softwares have Gaps driver (QINSY, NAVIPAC, HYPACK, STARFIX,
WINFROG, GECDIS). If your navigation software is not in this list, Gaps M7 and M5 can
emulate third party protocols (GPGGA, SONARDYNE, KONGSBERG) Most of the time,
