LEA-6 / NEO-6 / MAX-6
u-blox 6 GLONASS, GPS & QZSS modules
Hardware Integration Manual
Abstract
This document describes the features and specifications of the cost
effective and high-performance LEA-6, NEO-6 and MAX-6 GPS and
GPS/GLONASS/QZSS modules featuring the u-blox 6 positioning
engine.
These compact, easy to integrate stand-alone positioning modules
combine exceptional performance with highly flexible power,
design, and connectivity options. Their compact form factors and
SMT pads allow fully automated assembly with standard pick &
place and reflow soldering equipment for cost-efficient, high-
volume production enabling short time-to-market.

1.3.2 Operating modes
u-blox 6 modules with FW 7.0x or ROM6.02 have two continuous operating modes (Maximum Performance and
Eco) and one intermittent operating mode (Power Save mode). Maximum Performance mode freely uses the
acquisition engine, resulting in the best possible TTFF, while Eco mode optimizes the use of the acquisition
engine to deliver lower current consumption. At medium to strong signals, there is almost no difference for
acquisition and tracking performance in these modes.
1.3.2.1 Maximum Performance mode
In Maximum Performance mode, u-blox 6 receivers use the acquisition engine at full performance to search for
all possible satellites until the Almanac is completely downloaded.
As a consequence, tracking current consumption level will be achieved when:
• A valid GPS position is fixed
• Almanac is entirely downloaded
• Ephemeris for all satellites in view are valid
1.3.2.2 Eco mode
In Eco mode, u-blox 6 receivers use the acquisition engine to search for new satellites only when needed for
navigation:
• In cold starts, u-blox 6 searches for enough satellites to navigate and optimizes use of the acquisition
engine to download their ephemeris.
• In non-cold starts, u-blox 6 focuses on searching for visible satellites whose orbits are known from the
Almanac.
In Eco mode, the u-blox 6 acquisition engine limits use of its searching resources to minimize power
consumption. As a consequence the time to find some satellites at weakest signal level might be slightly
increased in comparison to the Maximum Performance mode.
u-blox 6 deactivates the acquisition engine as soon as a position is fixed and a sufficient number (at least 4) of
satellites are being tracked. The tracking engine continues to search and track new satellites without orbit
information.
1.3.2.3 Power Save mode
u-blox 6 receivers include a Power Save Mode. Its operation is called cyclic tracking and allows reducing the
average power consumption significantly. The Power Save Mode can be configured for different update periods.
u-blox recommends an update period of 1s for best GPS performance. For more information, see the u-blox 6
Receiver Description including Protocol Specification [4]
Dead Reckoning, PPP and Precision Timing features should not be used together with Power Save Mode.
Power Save Mode is not supported in GLONASS mode.
1.4 Antenna supply - V_ANT (LEA-6)
LEA-6 modules support active antenna supply and supervision use the pin V_ANT to supply the active antenna.
Use a 10 Ω resistor in front of V_ANT. For more information about antenna and antenna supervisor, see section
2.6.
If not used, connect the V_ANT pin to GND.
