GNS 1301
Module for GPS/GLONASS/GALILEO
The GNS1301 module utilizes the new generation MediaTek MT3333 GNSS chip that supports GPS and GLONASS simultaneously. Upgrading firmware, GNSS sytstems like GALILEO can be supported. Choosing the prevered GNSS system, GPS+GLONASS or GPS+GALILEO GNSS signals can be handled.
Due to its capability to use GLONASS and GPS at the same time, GNS1301 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).
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 module 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 90mW@ 3.3V) and internal voltage regulator makes it easy to run the module with various power supplies and allows direct connection to LiIon batteries.
