GPS & GLONASS module
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
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 66mW@ 3.3V) and internal voltage regulator makes
it easy to run the module with various power supplies and allows direct connection to LiIon
Further power savings re possible with AlwaysLocateTM 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.
GNS3301 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 MTAICTM ( 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.
