Jumpstar A12 RTK High-Precision Terminal
4G Cat.1, IMU Inertial Navigation, Dual-Antenna Attitude Output
The A12 is a full-band RTK high-precision vehicle-mounted positioning terminal with a built-in TF card slot and SIM card slot. It supports connection to various peripherals such as digital fuel level sensors via the RS232 interface for data collection and uploading to the fleet management platform. It adopts dual-antenna positioning to output heading and pitch attitude information, and integrates an IMU inertial navigation unit to automatically calculate latitude and longitude data in environments without satellite signals.
It also supports remote vehicle power/fuel cut-off and restoration through an external relay. Widely used in intelligent transportation, IoV, intelligent driving, logistics, freight and long-distance transportation scenarios.
RTK 2cm±1ppm, IMU dead reckoning, dual-antenna heading, IP66, 4G Cat.1 — A12 is the ultimate high-precision vehicle terminal.
