Promotion Product-MC-1612-DG

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.
