1 Introduction
Vincotech’s GPS receiver module / smart antenna A1035-H is a highly integrated
GPS antenna receiver module based on the technology of the GPS receiver mod-
ule A1084 and a ceramic GPS patch antenna. Like on the A1084-A an RF switch is
integrated on the module allowing changing of RF input from the on-module an-
tenna to an external antenna. The module is capable of receiving signals from up to
20 GPS satellites and transferring them into position and timing information that can
be read over a serial port. Small size and high-end GPS functionality are combined
at low power consumption:
•Operable at 3.3V / 24mA (typ.) @ 1fix per second
•UART interface at CMOS level
•Small form factor of 30.48 x 16.51 mm² (1.2” x 0.65”)
•Supported temperature range: -40°C to +85°C
•Single-sided SMT component, for reflow soldering
•RoHS compliant, lead-free
•Tape & reel packaging
•Excellent antenna support
oOn-module patch antenna
oAntenna input for direct connection of external active antenna
oRF switch to select between antennas
The receiver / smart antenna module is available as an off-the-shelf component,
100% tested and shipped in tape-and-reel.

1.2 Characteristics
The module is characterized by the following parameters.
1.2.1 GPS Characteristics
Channels 20, parallel tracking
Correlators 200,000 plus
Frequency L1 (= 1,575 MHz)
Tracking Sensitivity
External active antenna
On-module antenna
-159 dBm
-157 dBm
Horizontal Position Accuracy Stand alone < 2.5 m CEP (SA off)
Position Accuracy Stand alone < 10 m CEP (SA off)
Obscuration recovery (1) 0.1 s
Hot start (2) < 1 s
Warm (3) < 32 s
Time To First Fix – TTFF
(theoretical minimum values;
values in real world may differ)
Cold (4) < 35 s
Table 1: A1035-H 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.
Note: Performance (sensitivity and TTFF) might slightly decrease below -30°C.
