GNS3301

GPS & GLONASS module GNS 3301 Datasheet preliminary specification 1 INTRODUCTION The GNS3301 module supports GPS and GLONASS simultaneously. With a very small form factor of just 10.0 by 9.3 by 2.0 mm, GNS3301 is an ideal GNSS solution for many applications. GNS 3301 is based on the advanced new generation MediaTek MT3333 GNSS chip. First Fixes after just a few seconds are achieved with the help of A-GPS using EPOTM (Extended Prediction Orbit) and the EASYTM “self generated orbit prediction” algorithm. EASYTM (Embedded Assist System) does not require any resources and does not need any information from the network. Due to its capability to use GLONASS and GPS at the same time, GNS3301 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 or DGPS(RTCM). The low power design makes it easy to implement this module in power sensit...
