Operating modes
The u-blox AMY-6M features one continuous operating mode (Eco Mode)
Eco Mode
In Eco Mode, u-blox AMY-6M uses the acquisition engine to search for new satellites only when needed for
navigation:
In cold starts, u-blox AMY-6M searches for enough satellites to navigate and optimizes use of the acquisition
engine to download their ephemeris.
In non-cold starts, u-blox AMY-6M focuses on searching for visible satellites whose orbits are known from
the Almanac.
In Eco Mode, the u-blox AMY-6M acquisition engine limits use of its searching resources to minimize power
consumption.
u-blox AMY-6M 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.
Power Save Mode and Maximum Performance Mode are not supported by AMY-6M.
Power Save Mode requires an external RTC crystal to schedule system wake-up at pre-defined
intervals.
