1.5 GNSS

u-blox MAX-7 positioning modules are GNSS receivers and can singly receive and track GPS (including SBAS and

QZSS) and GLONASS signals. QZSS and SBAS signals (by default) can be received concurrently with GPS signals.

1.5.1 GPS

u-blox MAX-7 positioning modules are designed to receive and track the L1C/A signals provided at

1575.42 MHz by the Global Positioning System (GPS).

1.5.2 GLONASS

The Russian GLONASS satellite system is an alternative system to the US-based Global Positioning System (GPS).

The MAX-7 series modules are capable of receiving and processing GLONASS signals using the same hardware

and provides the lowest power GLONASS functionality in the industry at low cost and with minimal integration

effort. In order to take advantage of GPS and GLONASS, dedicated hardware preparation must be taken during

the design-in phase, see the MAX-7 / NEO-7 Hardware Integration Manual [1] for u-blox design

recommendations.

The ability to receive and track GLONASS L1OF satellite signals with the same hardware results in an optimized

hardware BOM and allows design of GLONASS ready receivers where required by regulations.

GLONASS and GPS signals cannot be received and tracked simultaneously by u-blox MAX-7 modules.

1.5.3 QZSS

The Quasi-Zenith Satellite System (QZSS) is a navigation satellite overlay system for the Pacific region covering

Japan and Australia which transmits additional GPS L1C/A signals. u-blox MAX-7 positioning modules are able to

receive and to track these signals simultaneously with GPS, resulting in better availability, especially under bad

signal conditions e.g. in urban canyons.

1.6 Augmented GNSS
