1.5 GNSS
u-blox 7 positioning modules are GNSS receivers and can singly receive and track GPS, GLONASS, or Galileo
signals. QZSS signals may be received concurrently with GPS signals.
1.5.1 GPS
u-blox 7 receivers 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 u-blox 7 module is 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.
Note: GLONASS and GPS signals cannot be received and tracked simultaneously by u-blox 7 modules.
1.5.3 Galileo
When Galileo-L1 signals become available, u-blox 7 flash-based receivers will be capable of receiving and
processing them via a firmware upgrade. The ability to receive and track Galileo satellite signals will result in
higher coverage, improved reliability and better accuracy.
1.5.4 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 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.
