GPS & BEIDOU module GNS 3301B Datasheet
▲The GNS3301B module supports GPS and BEIDOU simultaneously. With a very small form factor of just 10.0 by 9.3 by 2.0 mm, GNS3301B 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 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 BEIDOU and GPS at the same time, GNS3301B 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 (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.
▲GNS3301B 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.
