· Quantization bits:  4bit, 8bit, 16bit;

· Recording time: The maximum 16 hours support;

· Power output range: 20dBm ~ 50dBm;

· Data import /export interface : Ethernet;

· Support electric power supply and on-board power;

Functional characteristics

· Support the three systems: BDS, GPS, GLONASS, Galileo

· The frequency can be selected, the quantization bits can be set;

· Display the current location of satellite navigation state;

· Support fast data export.

Applications:

Satellite navigation receiver test system of vehicle and missile in a certain unit, the GNSS signal recording device is put in the car or plane, driving or flying along the established route, to collect and storage navigation satellite signal in the process.

In the factory, playback the scene recorded by the transmitting antenna, which can be used for the satellite navigation receiver, to avoid the test of repeated driving and flying.
