switching between full power in tough GPS environments and low power in strong GPS signal areas. When signal
levels drop, the receiver returns to full power so that message output rates remain constant. This results in variable
power savings but much more reliable performance for a fixed output rate. Applications using ATP should give
performance very similar to full power, but with significant power savings in strong signal conditions. ATP is best
suited for applications that require solutions at a fixed rate as well as low power consumption and still maintain the
ability to track weak signals. With ATP at a 1 second update, a power saving of 50% can easily be achieved with
minimal degradation in navigation performance.
3.4.2 Push-To-Fix mode
Push-To-Fix mode always forces the GPS software to revert to a continuous sleep mode after a navigation position
fix. It will stay in sleep mode until woken by activation of the WAKEUP input , and compute a fresh position. If
the ephemeris data become invalid, the RTC has the ability to self activate and refresh the data, thus keeping the
restart TTFF very short. This mode yields the lowest power consumption of the module, and is ideal where a battery
powered application requires very few position fixes. For further information refer to the Low Power Operating Modes
application note, Navman NMEA reference manual and the SiRF Binary Protocol reference manual.
