Inhaltsangabe:
- <p>System Purpose</p> <p>This FPGA firmware implements a complete Navigation and Solar Position subsystem for an AESA radar platform. It integrates three independent sensor pipelines into a unified data bus:</p> <p>| Pipeline | Sensor | Interface | Primary Output | |----------|-------------------|------------------------|-----------------------------------------| | GNSS | u-blox ZED-F9P | SPI (UBX protocol) | Position, velocity, UTC time, PPS | | IMU | Xsens MTi-630 | CAN 2.0B 1 Mbit/s | Attitude, inertial data, SDI, HR data | | SPA | Computed | Internal | Solar azimuth, elevation, zenith |</p> <p>The system also provides:</p> <ul> <li>GPS-disciplined 1 Hz PPS output with IEEE 802.1AS / TSN timestamping</li> <li>Full NREL Solar Position Algorithm (SPA) including sunrise/sunset/transit/EoT</li> </ul>
