GNSS Record and Playback System
The system is designed for outside use, implementing records of GNSS signals and long-term carrier trajectory. The system playback recorded data in other sites such as laboratories and buildings.
The system is based on the NI PXI platfomr and features hardware that includes the active antenna’s power supply, RF signal preamplifing and splitting box, transceivers, and more. For user comfort, the system includes a touch panel to avoid using a keyboard and mouse.
The system software is developed in the NI LabVIEW graphical programming environment with the LabVIEW FPGA Module which significantly ease the implementation.a keyboard and mouse.
