Global satellite navigation GNSS signal recording and playback device

DvBei DBS-01 Global Satellite Navigation GNSS Signal Recording and Playback Instrument：

Actual satellite navigation signals can be collected and stored in the form of records within the device, and the records can be repeated multiple times in a laboratory environmentGlobal satellite navigation GNSS signal recording and playback deviceReplay and complete the testing of the actual performance of satellite navigation terminals in a laboratory environment.
The DBS-01 series acquisition and playback device can collect and playback satellite navigation signals on multiple frequency bands with different quantization accuracies according to the requirements of testing tasks.

Features:
♦ DBS-01 has sampling information recording, storage, and playback functions. Can convert the collected satellite navigation signals into sampling information files and store them inside the device; Ability to select stored records and replay the satellite navigation signal to the tested terminal in the laboratory;
♦ Capable of recording, uploading, and downloading. Capable of using gigabit network to upload records stored inside the device to a PC, or downloading records already uploaded to a PC to the device's internal storage.
