Functional Description 1.1. Overview CruizCore®GD8000是DR / GNSS信号处理模块，可提供持续精确的导航 严酷的GNSS环境中的信息。该产品需要外部里程表和后退 用于DR / GNSS操作的信号（或通过RS-232C的速度信息）。该产品保证连续 位置报告甚至所有GNSS信号都被遮挡。在许多城市驾驶的情况下，高层建筑和 狭窄的街道掩盖了大部分或全部GNSS信号。这些城市峡谷也会降低其能见度 GNSS通过反射或多路径发出信号。在城市峡谷条件下，该产品具有 拒绝降级的信号条件。 GD8000提高了定位精度和可用性 航位推算功能。它通过联邦卡尔曼滤波器优化汽车的位置信息 方法。里程表，陀螺仪和加速度计的测量结果集成在产品中 与GNSS导航信息。里程表，陀螺仪和加速度计的测量是 与GNSS导航信息集成，提供更准确的位置估计 独立系统。该产品将在地图上报告地图辅助DR / GNSS导航解决方案 帮助消息从地图软件输入GD8000。 1.2.

System start-up Table 1 Start-up mode Start-up modes Description *DR cold start 在冷启动期间，系统需要稳定时间，这可能需要大约10分钟（GNSS修复和超过 40km / h的速度驾驶条件） DR warm start 设置参数后，DR / GNSS将以热启动模式启动。 * 在稳定时间期间，DR / GNSS的性能主要基于GNSS，一旦确定了参数，DR / GNSS将所有传感器 数据组合到估计位置。 4 CruizCore® GD8000 SPECIFICATION 1.5. Installation Mounting in the Vehicle GD8000 must be mounted securely in the vehicle so that it cannot move. Mounted angle of GD8000 is allowed within ±30deg. For the best performance of GD8000, zero mounted angle is recommended. Pay careful attention to the forward direction when installing the product.

Microinfinity can provide customized formats as an option. The CruizCore® DR/GNSS communicates with external devices using a serial RS232 interface with following parameters. Table 2 Serial Default Setting Baud Rate per second 115,200 Data bits 8 Stop bits 1 Parity Check No The GD8000 provides information to external devices using NMEA like messages. Table 3 NMEA Message NMEA Record Function Description GPDRH Microinfinity DR data Transmit from CruizeCore® GPGGA Global positioning system fixed data Transmit from GNSS GPRMC Recommend minimum specific data Transmit from GNSS --GSV GNSS satellites in view Transmit from GNSS --GSA GNSS DOP and active satellites Transmit from GNSS All messages are NMEA compatible 6 CruizCore® GD8000 SPECIFICATION 2.

Speed & direction operation GD8000可以使用“命令模式”或“里程表脉冲模式”运行。 当同时执行串行输入和脉冲输入时，它以“命令模式”运行，并忽略脉冲。 至少有一个有效数据，它 在“命令模式”下运行。 一旦检测到模式，它将一直保持到发动机停止。 因此，如果在操作期间交替执行命令和脉冲输入，则可能会发生故障。 ■ Command mode Name Type Value Units STX unsigned char 0xAF Start of Packet MSG unsigned char 0x20 Message Type LEN unsigned char 0x03 Length of DATA INDEX unsigned char 0 ~ 255 Index of Packet SPEED unsigned short int (Byte order : Little endian) 0.01 Km/h Description Speed information Ex) 12345 = 123.45Km Backward Direction, DIR_BACK CS unsigned char 0x00 : Forward, 0x01 : Backward Exclusive-OR(XOR) of all the bytes in the message between the MSG and DIR_BACK. unsigned char The initial value of CS is 0x00.
