DESCRIPTION
The SG Series GPS receiver module is a self-
contained high-performance GPS receiver with an
on-board LNA and SAW filter. Based on the SiRFstar
III chipset, it provides exceptional sensitivity, even in
dense foliage and urban canyons. The module’s very
low power consumption helps maximize runtimes in
battery powered applications. With over 200,000
effective correlators, the SG Series receiver can
acquire and track up to 20 satellites simultaneously in
just seconds, even at the lowest signal levels.
Housed in a compact reflow-compatible SMD
package, the receiver requires no programming or
additional RF components (except an antenna) to form a complete GPS solution.
Five GPIOs are easily configured through simple serial commands. These features,
along with the module’s standard NMEA data output, make the SG Series easy to
integrate, even by engineers without previous RF or GPS experience.
