Introduction to the Navico Broadband radar system | 7
Radar system overview
The Navico Broadband radar is a state of the art navigation aid providing outstanding radar
performance with out the limitations of conventional pulse radars such as dangerous high power
microwaves, Standby warm up time, high power consumption and large open arrays which is
what would be required to obtain the same image quality at shorter ranges . The Navico
Broadband radar as an effective range from 1/16 to 24 nm. and has an operating power
consumption of 17 W.
The system consists of radar scanner, an interface box and a interconnection cable. The scanner
is housed in a dome on is of similar size to most 2 kW radars on the market.
The interface box is used to connect displays and heading information. There are two models
(RI-10 and RI-11) depending on the display system used the main difference being one has a
SimNet connector for heading input (RI-10). The other interface box (RI-11) has a connector to
interface to RS422 displays and NMEA 0183 heading sensors. both interface boxes have a
Network connector to interface to Ethernet displays.
Note Lowrance HDS units sold in the USA do not require an interface box and the scanner
connects directly to the display or ethernet switch

*For best chart overlay performance use a heading sensor. Course over ground can be used but
only when moving
** For MARPA it is essential to use a heading sensor with an out put speed of 10 hZ or faster
