Range capabilities
The range capabilities of an acoustic system are dependent of
the vessels noise level and attenuation of the transponder signal
level due to ray bending. The transponder source level and the
signal to noise ratio are crucial factors for calculating maximum
range capability. The below figures are recommended guideline
for maximum operating range.
Please also be aware of:
The figures are valid for HiPAP® 501/351/451
Figures for cNODE
®
are when used in Cymbal mode
(Wideband)
The HiPAP® system will in many cases have longer range
capabilities that specified below due to its narrow receiving
beam.
The figures are approximate values for guidance.
Ray bending can limit the maximum range
Ray bending normally not a problem for vertical positioning
operation
