1.5 Characteristics
The module are characterized by the following parameters.
1.5.1 GPS Characteristics
(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.
1.5.2 Mechanical Characteristics
1.6 Handling Precautions
The GPS receiver module A2200-A is sensitive to electrostatic discharge (ESD).
Please handle with appropriate care.
