1.5 Characteristics
The modules are characterized by the following parameters.
1.5.1 GPS & GLONASS Characteristics
Channels
Correlators
Frequency
Tracking Sensitivity
Horizontal Position Accuracy
Time To First Fix – TTFF
(theoretical minimum values;
values in real world may differ)
(1) Typical with good antenna – see also paragraph "3.2 Antennas"
(2) The calibrated clock of the receiver has not stopped, thus it knows precise time (to the µs level).
(3) The receiver has estimates of time/date/position and valid almanac and ephemeris data.
(4) The receiver has estimates of time/date/position and recent almanac.
(5) The receiver has no estimate of time/date/position, and no recent almanac.
Note: Performance (sensitivity and TTFF) might slightly decrease below -30°C.
