The MKT4052 Dual-Antenna MEMS Inertial-Satellite Integrated Navigation System utilizes high-precision MEMS (Micro-Electro-Mechanical System) gyroscopes, accelerometers, and multi-mode, multi-frequency GNSS receivers to real-time calculate the position, velocity, heading, and attitude of the carrier, achieving dual-antenna-assisted fast and high-precision orientation and integrated navigation functions. The system supports real-time GNSS RTK (Real-Time Kinematic) functionality and offers advantages such as anti-obstruction, anti-multipath interference, high precision, compact design, small size, and lightweight. It is applicable in fields such as memory parking, L2++ intelligent driving, L3+ integrated driving and parking autonomous driving (when combined with automotive suppliers’ or OEM’s domain controller systems or T-box), and L4 autonomous driving (when combined with low-speed unmanned vehicles or robotic domain controller systems). The product accessories include feedlines and antennas, with optional configurations for ground-based RTK reference stations, 4G communication modules, and more.   Performance Indicators Frequency Points GPS: L1 C/A L2C BDS: B1 B2 GLONASS: L1 L2 Positioning Accuracy Single Point≤2m (CEP) RTK≤2cm+1ppm (CEP) Velocity Accuracy ＜0.05m/s (1σ) Heading Accuracy 0.2° (Baseline Length 1m) (1σ) (Orientation) GNSS Loss of Lock Accuracy Three Thousandths (Error to Loss of Lock Distance Ratio) Initialization Time <10s TTFF <35s Update Rate 100Hz (Configurable) Output Protocol GIAVP Hexadecimal Protocol 1 Hexadecimal Protocol 2 (Custom Hexadecimal Protocol) Baud Rate 115200~460800bps (Configurable) Supports Vehicle Information Input Supports External Wheel Speed and CAN Input  (DBC Compatible) Inertial Navigation Characteristics Pitch and Roll Angle Accuracy 0.1°(1σ) Acceleromete Range: ±6g Zero Bias Stability: 0.06mg Gyroscope Range: ±300°/s Zero Bias Stability: 10°/h Physical Characteristics Operating Voltage DC/24V Rated (10~32V) Power Consumption 160mA@12V Function Interface RS232 RS422 PPS CAN Product Dimensions Length 116mm * Width 83mm * Height 37mm Module Model Description Murata634 UM982 Antenna RTK Mushroom Antenna IP Protection Rating IP65 Operating Temperature -25~65℃ Storage Temperature -30~80℃
