Portable GNSS Recorder and Playback Device

Page views：

Product overview

The Portable GNSS Recorder and Playback Device is a comprehensive test solution that integrates high-fidelity signal recording and playback,real-time forwarding,and signal monitoring.It supports synchronized recording,playback,and forwarding of full-band GNSS signals(GPS/BDS/Galileo/GLONASS,etc.)and utilizes 1 to 4 expandable channels to enable parallel processing of multiple signals.With a closed-loop monitoring feature,it provides an accurate and reliable signal environment for indoor testing.

The device is designed with user-friendly features,supporting touchscreen operation and remote control via network,simplifying the testing process.Its portable architecture allows for rapid deployment in the laboratory or field environments,effectively avoiding the signal uncertainty encountered in traditional field testing.It provides a stable and controllable testing solution for scenarios such as navigation terminal verification,anti-jamming tests,etc.

Functional advantage

Multi-Constellation Signal Acquisition and Controllable Frequency Bands

Capable of acquiring signals from major satellite navigation systems such as GPS,BDS,Galileo,GLONASS and storing the acquired signals in file format internally.The frequency bands for each acquisition channel are controllable
Flexible Signal Playback with Adjustable Power

Capable of storing the acquired satellite navigation signals,supporting playback in single or multiple iterations as specified,with adjustable playback power
Closed-Loop Monitoring and status output

Capable of closed-loop monitoring of satellite navigation signals processed within the device,providing information such as frequency points,visible satellites,and carrier-to-noise ratio(C/N0)
Dual-Mode Data Interaction Interface

Supports the import and export of stored satellite navigation signal records,enabling data interaction between the PC and the device via network ports or detachable hard drive mode
Clock Synchronization Function

Supports clock synchronization,enabling synchronized signal acquisition and playback across multiple devices
Controllable Delayed Signal Forwarding (Optional)

Capable of forwarding satellite navigation signals from major navigation systems,with controllable forwarding delay
Full System Compatibility and Precise Parameter Control

Supports signal acquisition from major navigation systems.Key parameters such as acquisition frequency bands,playback power,and forwarding delay are fully adjustable
Dual-Mode Data Interaction and Dual-Control Operation

Supports both network interface and detachable hard drive data interaction methods; features a dual-control mode with both touchscreen and Ethernet control, balancing convenience and flexibility
Multi-Device Synchronization and Closed-Loop Monitoring Capability

Uses clock synchronization technology to enable collaborative operation of multiple devices.The closed-loop monitoring function provides real-time feedback on key signal status parameters
