1. Introduction
1.1. The AS07-0183
The QK-AS07 is a high-accuracy, GPS, Glonass and Galileo GNSS positioning sensor for use in
vessels, automotive, fleet vehicle, and others where that require a small, highly accurate positioning
receiver.
AS07-0183 features superior sensitivity for consistent signal acquisition, reliable position accuracy, and
accurate speed and course-over-ground readings. The AS07 is designed for marine environments and
suitable for other outdoor and vehicular use, with an IPX6 waterproof housing.
The AS07-0183 can be connect directly to the NMEA 0183 devices with RS422 interface. It is powered
by 12V.
The AS07-0183 can be used out of the box, to provide instant positional data to NMEA 0183 devices.
Alternatively, the AS07-0183 can be connected via a USB/RS422 adaptor with a Windows computer..
This provides additional configurations:
Filtering of desired NMEA 0183 sentences, to eliminate unwanted data.
Adjusting the frequency of NMEA 0183 output rate (1/2/5/10 per second).
Adjusting the data output baud rate(4.8k,9.6k,38.4k,115.2k bps)
1.2. GPS, Glonass and Galileo GNSS
The AS07-0813 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 accesses more than one GNSS, the AS07-0813:
increases location accuracy and
maximizes reliability in case one system is out of range or inaccessible.
