GPS receiver A1080-A
1 Introduction
Tyco Electronics’ GPS module A1080-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
20 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 low power consumption:
•Operable at 3.3V / 36mA (typ.) @ 1fix per second
•Small form factor of 19 x 16.2 mm (0.75” x 0.64”)
•Cost-effective antenna input
•Single-sided SMD component, for reflow soldering
•Tape & reel packaging
The A1080-A GPS receivers are available as off-the-shelf component, 100% tested
and shipped in standard tape-and-reel package.
1.1 Label
The A1080-A label holds the following information:

1.2 Characteristics
The modules are characterized by the following parameters.
1.2.1 GPS Characteristics
Channels 20, parallel tracking
Correlators 200.000 plus
Frequency L1 (= 1575 MHz)
Tracking Sensitivity -159dBm
Position Accuracy Stand alone < 10m CEP (SA off)
Horizontal Position Accuracy Stand alone < 2,5m CEP (SA off)
Obscuration recovery (1) 0.1s
Hot start (2) < 1s
Warm (3) < 32s
Time To First Fix – TTFF
(theoretical minimum values;
values in real world may differ)
Cold (4) < 35s
Table 1: A1080 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.
