GPS receiver A1082-A
1 Introduction
Tyco Electronics’ GPS module A1082-A is a highly integrated GPS receiver module
that can be used as an SMT component. It is capable to receive signals from up to
12 GPS satellites and transferring them into position and timing information that can
be read over a serial port. This new generation of GPS module combines small size
and high-end GPS functionality at lowest power consumption:
• Operable at 1.8V / 65mW (typ.) @ trickle power mode
• Small form factor of 13.97 x 11.43 mm (0.55” x 0.45”)
• Cost-effective antenna input
• Single-sided SMD-BGA component, for reflow soldering
• Tape & reel packaging
The A1082-A GPS receivers are available as off-the-shelf component, 100% tested
and shipped in standard tape-and-reel package.

Table 1: A1082 GPS characteristics
(1) The calibrated clock of the receiver has not stopped, thus it knows precise time (to the µs level).
(2) The receiver has estimates of time/date/position and valid almanac and ephemeris data.
(3) The receiver has estimates of time/date/position and recent almanac.
(4) The receiver has no estimate of time/date/position, and no recent almanac.
(5) CEP 50% 24 hours static
