The Linx Technologies SG Series and SR Series GPS receiver modules are self-contained, high-performance GPS receivers with an on-board LNA and SAW filter. The SG / SR GPS receiver module is based on the SiRFstarIII chipset and provides exceptional sensitivity even in dense foliage and urban canyons. These Linx Technologies GPS receiver modules provide very low power consumption and help maximize runtimes in battery powered applications. The SG series can acquire and track up to 20 satellites simultaneously in just seconds even at the lowest signal levels and requires no programming or additional RF components (except an antenna) to form a complete GPS solution. The SR Series includes an integrated antenna. The SG and SR Master Development System kits give designers all the tools necessary to correctly incorporate the SG and SR series into an end product.
