GNS702

GPS/GLONASS receiver GNS702 Datasheet V1.2 preliminary specification 1 INTRODUCTION GNS702 is a small autonomous GPS/GLONASS receiver, based upon the MediaTek MT3333 single chip, available with a finely tuned, high-sensitivity ceramic chip antenna. The receiver supports GPS and GLONASS simultaneously. The navigation performance and accuracy is further improved by using correction data from SBAS (WAAS, EGNOS, GAGAN, MSAS), QZSS. 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 or assist data from the host. The excellent low power design makes it easy to implement this receiver in power sensitive, battery supplied applications. The new AlwaysLocateTM power management feature will improve this behaviour additionally. It adaptively adjusts power consumption depending on the environment and motion conditions, in order to achive a balance between fix rate, power consumption and position accuracy. Very low power requirements (typ 93mW@ 3.3V, tracking for GPS+GLONASS) and internal voltage regulator makes it easy to run the receiver with various power supplies and allows direct connection to LiIon batteries. GNS702 offers the industry’s highest level of navigation sensitivity up to -165dBm1. It has superior dynamic performance at high velocity and provides effective protection against interference ...
