GNS 902B GPS BEIDOU(BDS) Chip Antenna Module MT3333

GNS902B is a small autonomous GPS/BEIDOU receiver, based upon the MediaTek MT3333 single chip, available with a finely tuned, high-sensitivity ceramic chip antenna. The receiver supports GPS and BEIDOU 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 67mW@3.3V, tracking for GPS+BEIDOU) and internal voltage regulator makes it easy to run the receiver with various power supplies and allows direct connection to LiIon batteries.

GNS902 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 signals using MTAICTM ( Multi-tone active interference canceller). Up to 12 independent channel interference continious wave jammers <-80dBm can be eliminated or reduced.

 

The embedded logger function LOCUS with a 16-hrs on chip memory makes this GPS module a complete track logger for many applications.

In professional timing applications the outstanding high accuracy PPS (pulse per second) hardware pin is used for synchronization to GPS second. Typical accuracy is 10ns RMS.

Note: This module is designed to be operated on a mainboard, that provides a minimum of 20mm x 30mm ground plane. Sensitivity will be decreased if no groundplane is provided.
