Radar system overview
The Navico Broadband radar is a state of the art navigation aid. It provides outstanding radar
performance without the limitations of conventional pulse radars such as: dangerous high power
microwaves, standby warm up time, 30 m blind spot (mainbang), 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 has an effective range from 200 ft to 24 nm and has an operating
power consumption of 19 W and stand-by power consumption of 2 W.
The system consists of: radar scanner, an interface box and an interconnection cable. The
scanner is housed in a dome of similar size to most 2 kW radars on the market.
The interface box is used to connect displays, power and heading information. There are two
models: RI10 and RI11. Depending on the display system used, the main difference is that -
one has a SimNet (Simrad NMEA 2000) connector for heading input (RI10). The other interface
box (RI11) 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.
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 output speed of 10 Hz. Heading
sensor needs to be a rate gyro stabilized compass or better.
