GNS 202 GPS Chip Antenna Module MT3337


The new GNS202 is an easy to implement and very economical complete GPS receiver that is based on mediatek’s ROM chip technology. It can run from regulated supplies as well as directly with LiIon battery.

GPS engine, all clocks with RTC, an internal LNA, a SMPS

power management circuit, a high precision time base and a high efficient chip antenna are all integrated in the module. Adding a single power supply is all that is needed to operate. Lowest power requirements (14mA full power tracking current), small size, highest sensitivity, and many useful features make this solution an ideal choice for GPS-only applications. Further energy savings can be achieved by using one of the internal power saving functions.

The navigation performance and accuracy is further improved by using the correction data from SBAS (WAAS, EGNOS, GAGAN, MSAS), QZSS. The module measures just 15.7 by 10 by 2.0 mm.

GNS202 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. The MTAICTM (Multi-tone active interference canceller) can eliminate up to 12 channel interferences.
