The PBOX is a compact tight coupling navigation receiver independently developed by A&I. This receiver adopts a vehicle-grade chip solution and ruggedized interfaces, making it more suitable for operation in harsh environments. The receiver supports full constellation and full frequency band, and is equipped with Ethernet, RS422 serial port, RS232 serial port, CAN, and PPS interfaces. With the unique measurement-free / self-calibration algorithm and the multi-strategy positioning algorithm engine, it can still output stable and reliable position and attitude information in challenging environments such as dense foliage obstruction and urban canyons.
Automotive-grade Design
The receiver is equipped with an automotive-grade GNSS chip and an IMU with ASIL B functional safety level. It uses automotive-grade connectors such as FAKRA, which are commonly found in vehicle front-end applications, ensuring both safety and reliability with excellent cost performance.
Redundant Backup Algorithm Engine
The positioning engine integrates the advantages of various algorithms such as PVT, RTK, loose and tight coupling navigation. It incorporates multi-strategy redundant backup and establishes two sets of interference and anomaly signal detection algorithms for GNSS and IMU, enhancing positioning reliability and accuracy in harsh environments.
Rich Peripheral Interfaces
Supports multiple interfaces, including Ethernet, CAN, RS422, RS232, and PPS. It also supports PPS, GPTP, and NTP time synchronization, enabling seamless integration with other sensors (such as Lidar, domain controllers) for coordinated operation.
Scene Optimization
The system is optimized for typical scenarios such as low-speed vehicle applications, ports, and mines. It is capable of handling complex road conditions (such as speed bumps, rough roads, overpasses, tunnel entrances and exits), providing continuous, stable, and reliable real-time high-precision position and attitude services for various vehicle types, including tracked and wheeled vehicles.
