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.

ADR mode, MC-1612-DG have high-precision positioning and dead reckoning performance, offers real-time 1.5m accuracy positioning and heading with low-power consumption. The software includes features to receive and use data from the built-in sensors along with external signals for wheel speed and Forward/Reverse direction, the vehicle signals are used to provide a high level of accuracy in the navigation solution. It features high sensitivity, low power and ultra-small form factor, and provide user the superior performance.

UDR mode, MC-1612-DG when under the environment with pool signal like tunnels, urban and under grounder also unable to gain the speed through vehicle, UDR will play the role to keep positioning by the built-in MEMS which means MC-1612-DG keeps to perform the capacity of seamless positioning with UDR where the application at the environment above.

MC-1612-DG have both GNSS/ADR/UDR | 3-in-1 Seamless Positioning

MC-1612-DG offers the full-coverage positioning functionalities wherever the poor-signal environment or the installation position and keep to output high positioning performance for your applications might be under harsh environment. In the mean time, your design will be benefited from applying MC-1612-DG, the 3-in-1 solution so that easy to design (You can choose to have physical speed input or not) saving time and efforts and boost the high positioning performance exceed your expectation.
