The SG and SR series of GPS modules can be easily applied and blend high performance, low power, and cost effectiveness into a single, compact SMD package. The module’s SiRFstar III low-power chipset minimizes power consumption and provides exceptional sensitivity, even in dense foliage and urban canyons. The receivers feature an on-board LNA and SAW filter, as well as an integrated antenna (SR version) or external antenna (SG version), which further lowers cost and reduces complexity. No other RF components are needed and the module’s standard NMEA data output makes them easy to integrate, even by engineers without previous RF or GPS experience.
