Description
The R4 Series GPS receiver module is a self-contained high-performance
GPS receiver with an on-board LNA and SAW filter. 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. These
features, along with the module’s standard NMEA data output, make it
easy to integrate, even by engineers without previous RF or GPS
experience. The Linx R4 Series GPS modules offer a simple, efficient and
cost-effective method of adding GPS capabilities to any product.
The evaluation module contains the surface mount R4 Series GPS module,
SMA connector and a ferrite bead (used to supply power to an external
active antenna, such as the Linx SH Series active GPS antenna) on a single
board with through-hole headers. This small board makes prototyping with
the R4 Series module very easy.
