Description
The Teseo-LIV3F module is an easy to use Global
Navigation Satellite System (GNSS) standalone
module, embedding Teseo III single die
standalone positioning receiver IC working
simultaneously on multiple constellations
(GPS/Galileo/Glonass/BeiDou/QZSS).
The Teseo-LIV3F modules bring the proven
accuracy and robustness of Teseo chips to the
reach of everyone: the embedded firmware and
the complete evaluation environment save
development time, while the compactness and
cost-effectiveness of this solution make it ideal for
several applications, such as insurance, goods
tracking, drones, tolling, anti-theft systems,
people and pet location, vehicle tracking,
emergency calls, fleet management, vehicle
sharing, diagnostics and public transportation.
Within its 9.7x10.1 mm tiny size, Teseo-LIV3F is
offering superior accuracy thanks to the on board
26 MHz Temperature Compensated Crystal
Oscillator (TCXO) and a reduced Time To First Fix
(TTFF) relying to its dedicated 32 KHz Real Time
Clock (RTC) oscillator.
Thanks to the embedded 16 Mbit flash Teseo-
LIV3F offers many extra features such as data
logging, 7 days autonomous assisted GNSS, FW
reconfigurability as well as FW upgrades.
Teseo-LIV3F provides also the Autonomous
Assisted GNSS able to predict satellite data
based on previous observation of satellite.
Teseo-LIV3F module, being a certified solution,
optimizes the time to market of the final
applications with a temperature operating range
from -40°C to 85°C.
