LOCOSYS MC-1612-DG is a single-band multi-system with an ARM base processor. It not only supports GPS, GLONASS, GALILEO, QZSS , but also has a flash memory, TCXO, RTC crystal, LNA and SAW filter, and embedded MEMS sensors (6-axis accelerometers gyros), 1-hole pressure (option) Micro-Electro-Mechanical Systems (MEMS) sensor, equipped with DR software. The extended Kalman filter algorithm combines GNSS and MEMS sensor data with a weighting function that relies on GNSS signal quality. With adverse GNSS conditions in urban canyons, tunnels, or parking garages where DR boosts the accuracy, and the software fills the gaps. It supports three dimensional DR, Standard NMEA output, fully supports various map mapping demand.

LS2003D-2RE is a complete standalone GPS smart antenna module, including embedded patch antenna and GPS receiver circuits.

LS2003D-2RE is a complete standalone GPS smart antenna module, including embedded patch antenna and GPS receiver circuits. The module's functionality is using MediaTek lateast GPS, MT3337E, ROM chip and it can
acquire a lot of satellites at a time while providing fast time-to-first-fix and low power consumption. Besides,
it can provide you with superior sensitivity and performance even in urban canyon and dense foliage
The new module supports self-generate orbit prediction, called EASYTM, to achieve faster cold start
and warm start. The EASYTMis no need of both network assistance and host CPU’s intervention. The
prediction is valid for up to 3 days and updates automatically from time to time when GPS module is powered
on and satellites are available.
It is easy to install without both RF connector and coaxial cable that are needed in a separated GPS
active antenna. In other words, reduce the cost and size. Also, speed up the time to market by eliminating
R&D efforts on RF matching and stability between separated GPS antenna and module. Furthermore, it can be
directly powered by a lithium battery without any external voltage regulators. Therefore, LS2003D-2RE of
miniature size and brilliant performance is the best choice to be integrated into your slim devices.
