GNS 2301 GPS GLONASS Module SirfStar V

The GNS2301 module utilizes the new generation CSR SirF V GNSS chip that supports GPS and GLONASS simultaneously.

Due to its capability to use GLONASS and GPS at the same time, GNS2301 benefits from the higher availability of satellites in critical environments. The navigation performance and accuracy is further improved by using the correction data from SBAS (WAAS, EGNOS, GAGAN, MSAS), QZSS.

First Fixes after just a few seconds are achieved with the help of three different A-GPS technologies. The module supports self prediction CGEE. Server based AGPS (SGEE) and realtime AGPS is available on request. These services are provided by CSR and are not free of charge. They are available only for high quantities.

GNS2301 is based on Sirf chipset of the 5th generation. It includes a ROM based software code and a patch RAM for later software improvements. Using the patch option is recommended by the chip manufacturer CSR.

Several Low Power Mode options make it easy to implement this module in power sensitive, battery supplied applications.

Low power requirements (~90mW@ 3.3V, full activity) and internal voltage regulators make it easy to run the module with various power supplies and allows direct connection to LiIon batteries.

GNS2301 offers the industry’s highest level of navigation sensitivity down to -165dBm. It has superior dynamic performance at high velocity and provides effective protection against interference signals. Up to 8 independent channel interference can be eliminated or reduced.

For easy test and evalution, a Starter Kit is available.
