avico Holding AS has acquired the
radar operations of Italy’s Consilium AB.
As part of the transaction, Navico
takes over all aspects of Consilium’s
radar business, including research
and development, product management and manufacturing.
Navico and Consilium have
also entered into a sales and
distribution agreement, under
which Consilium will continue
to sell and service the Consilium
Selux radar line as well as distribute Navico’s complete portfolio of
Simrad Professional products throughout its global sales and distribution network.
“This strategic acquisition further secures Navico’s position at the forefront of professional marine electronics by adding top quality radar products and competencies to its
Simrad Professional range of products,” according to Navico.
Leif Ottosson, president and CEO of Navico Holding AS, said, “The professional marine
market is a strategic priority for our growth ambitions. With the acquisition of Consilium’s
radar business and the sales and distribution agreement, we will obtain a very strong
proven technology and product portfolio to drive our continued expansion and success
within this sector.” (See interview on page 40.)
As part of this acquisition, Navico adds a highly talented team of professional radar
experts from design to manufacturing and sales to its core staff. The Consilium research
and manufacturing facilities in Italy, with over 50 years of radar experience, are now also
part of Navico.

By properly controlling the signals to these elements, the system can
shape and steer the output pulse. To accomplish this the sonar system
requires essentially the same DSP system as the radar system.
The situation with range resolution is similar to that of radar. To put
enough energy into the water to be able to identify distant targets
requires long duration pulses. However, to achieve good target resolution (separation) requires pulses of short duration. DSP enables the
adjustment of the pulse length as a function of the range setting so that
you can reach deeper depths without reducing the frequency and without loss of resolution. CHIRP sounders also make good use of DSP’s
noise and matched filtering capabilities.
VHF and SSB radio
An obvious area for applications of DSP is in marine radio communications. Icom has employed DSP in its M801 and 802 HF SSB and in
its new IC-506 VHF marine transceivers. Icom’s Active Noise Cancelling
feature uses digital signal processing technology in both the transmit
and receive modes. According to Icom, this feature reduces background
noise up to 90% in the received signal and 30% in the transmit mode.
A word of caution here. The underlying mathematics of digital sig-
nal processing gets a little too deep for wading or toe dipping. “If you
turn to the textbooks to learn and use DSP, you’re likely to find that it’s
page after page of equations, obscure mathematical symbols, and unfa-
miliar terminology,” says Dr. Smith. “It’s a nightmare! Much of the DSP
literature is baffling, even to those experienced in the field. However,
most practical DSP techniques can be learned and used without the tra-
ditional barriers of detailed mathematics and theory.”
After all, you don’t have to design these systems; you just have to
know how they work to know when they’re not. ME

depreciation allowance or 90% of the preceding year’s depreciation.
Under the proportionate depreciation allowance method, corporations estimate their depreciation deduction based on assets placed in
service as of the end of the previous year and by the end of the installment period. Using 90% of the preceding year’s depreciation to calculate
estimated tax payments may provide a tremendous benefit to taxpayers
reporting substantial tax depreciation under 2013’s favorable bonus
depreciation rules. ME
