6.3 GPS Power Management Features
Power management schemes implemented for any GPS system requires an optimally
tuned performance for both accuracy of the position fixes and the average power consumed for
best user experience. TC6000GN-P1 architecture achieves both these aspects by providing flexibility
and design choices for the system integration based on wide range of use cases and by leveraging
on the proven silicon methodologies. Also TC6000GN-P1 provides position, velocity and time (PVT)
measurements without any host loading. This, coupled with the optional built-in power
management option, reduces the overall system power budget.
Power management features
APM feature provides overall GPS system power consumption of 27mW in tracking mode
under open sky conditions
Can provide PVT solution without any load on the host, allowing a reduction in overall
system power consumption.
Position update rates selectable by order option. Max of 1 Hz update rate.
6.4 GPS almanac and ephemeris data
For quick re-acquisition of the GPS after off-times, the GPS engine should have access to almanac
and ephemeris data. This data is permanently stored inside TC6000GN module. When the GPS is
powered-up again, the data will be used to allow a quick re-acquisition, as soon as a coarse time
information is available.
6.5 Push to Fix
The Push to Fix signal is used to initiate a GPS fix session. The signal is defined as active high when
starting a GPS fix session. The session can be a cold, warm or host start fix, depending upon the
availablility and age of the assistance data.
