QK-AS07-0183 Manual

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.
