10.7 Extended Ephemeris
The receiver is capable of supporting two versions of using Extended Ephemeris
(EE) data. The first one is the version, where the EE data are calculated on a server,
are transmitted to device incorporating the receiver, and are then loaded into the
receiver. These data can be valid for up to seven days.
The second version is the internal extrapolation of available "natural" Ephemeris
data. This is done automatically and no external support is required. The internally
calculated EE data are valid for up to 3 days.
The receiver firmware will define which set of EE data to use or will neglect those in
case "natural" data are available. Both versions of EE data will help to further lower
TM
power consumption in SiRFaware
mode.
