Description

The R4 Series GPS receiver module is

a self-contained high-performance GPS

receiver. Based on the SiRFstar IV 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 R4 Series

receiver can acquire and track up to 48

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. The

module’s standard NMEA data output makes the R4 Series easy to

integrate, even by engineers without previous RF or GPS experience.
