1 INTRODUCTION

The GNS3303 module supports GPS and GLONASS and GALILEO simultaneously. With a very small

form factor of just 10.0 by 9.3 by 2.0 mm, GNS3303 is an ideal GNSS solution for many

applications.

GNS 3303 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 EPO

(Extended Prediction Orbit)

and the EASY

“self generated orbit prediction” algorithm. EASY

(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 and GALILEO at the

same time, GNS3303 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 sensitive, battery supplied

applications. Very low power requirements (typ. 72mW@ 3.3V) and internal voltage regulator

makes it easy to run the module with various power supplies and allows direct connection to LiIon

batteries.

Further power savings re possible with AlwaysLocate

power management feature. 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.

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 jitter.

GNS3303 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 using MTAIC

( Multi-tone active interference canceller). Up to 12 independent

channel interference continuous wave jammers can be eliminated or reduced.

The embedded logger function LOCUS

with a 16-hrs on chip memory makes this GNSS module a

complete track logger for many applications.
