Addressing the current issue of low positioning accuracy in Beidou navigation and positioning receivers under high dynamic and complex electromagnetic environments, this paper, based on an understanding of satellite navigation principles, introduces the design of an embedded Beidou navigation receiver based on DSP+FPGA, to meet the high-precision navigation and positioning requirements for UAVs, individual soldiers, robots, and other applications in high dynamic and complex electromagnetic environments.

Compared to the TMS320C6678 + Kintex-7 combination, the TMS320C6678 + ZYNQ combination offers more hardware resources, most notably the addition of two ARM Cortex-A9 cores, and features native Ethernet, USB, UART, CAN, SPI, I2C and other interfaces, as well as 16 GTX transceivers and up to 444K logic resources.

Key Aspects of the Solution

(1) Image Data Acquisition

High-speed, high-precision image data acquisition is performed using programmable logic devices (e.g., FPGA), with flexible connectivity to various cameras such as CameraLink, SDI, PAL, etc.

(2) Target Tracking and Analysis

Acquired image data is transmitted via high-speed data buses (e.g., SRIO, PCIe) to a digital signal processing platform (e.g., DSP), where algorithms are used for positional analysis of the image data.

(3) Target Image Monitoring

Processed images are displayed in real-time via interfaces such as CameraLink, HDMI, and the visualization interface can be controlled.
