1. Introduction
1.1. The AS07-N2K
The AS07-N2K contains two integrated sensors within the single unit
•
a multiple GNSS positioning sensor and
•
a three-axis magnetic compass.
The AS07-0183 can be used out of the box and features superior sensitivity for consistent signal
acquisition, reliable position accuracy, and accurate speed and course-over-ground readings. The AS07-
N2K is designed for marine environments and suitable for other outdoor and vehicular use, with an IPX6
waterproof housing. Additionally, from may 2021 onwards it also features heading information.
The AS07-N2K can be connect directly to the NMEA 2000 backbone. It is powered by the NMEA 2000
backbone with no need for additional configuration.
1.2. The AS07-C (optional purchase)
The AS07-N2K can be used out of the box, to provide instant positional and heading data to your NMEA
2000 bus.
Alternatively, the AS07-N2K can be used with the AS07-C Optional Output Switch. The AS07-C provides
additional Configuration/Conversion, specifically:
1. Optional additional configuration using Windows PC,
•
Filtering of desired NMEA 2000 PGN messages, to eliminate unwanted data.
•
Adjusting the frequency of NMEA 2000 data (1/2/5/10 per second).
•
Calibratable to compensate for magnetic deviation(very rarely required)
2. Backward compatibility with NMEA 0183 devices.
1.3. GPS, Glonass and Galileo GNSS
The AS07-N2K receives and process messages from GPS, Galileo and Glonass positioning
satellites. GPS, Galileo and Glonass are all space-satellite based navigation systems, also known
as Global Navigation Satellite Systems (GNSS).
•
GPS
(Global Positioning System), was created by the US government and operated by the
US Space Force.
•
GLONASS
provides a comparable alternative to GPS. It was created by Russia.
•
GALILEO
was created by the EU through the European GNSS Agency.
Global Navigation Satellite Systems work by triangulating data from several satellites. At least three
satellites from a system must be accessible/in range to triangulate a location fix.
By accessing more than one GNSS, the AS07
-N2K
:
•
increases location accuracy
•
maximizes reliability in the event one system/satellite is out of range or inaccessible.
1.4. Compass Heading
The AS07-N2K is actually two sensors in a single unit; a multiple GNSS positioning sensor and a three-
axis magnetic compass. Simply connect it to the NMEA 2000 backbone and it will immediately start
calculating the heading of the boat and outputting this data. You can filter out this message type if not
required (using the Windows Configuration tool with AS07-C).
