GNSS Signal Acquisition Platform Design
This paper mainly focuses on a GNSS IF signal acquisition platform; the platform is comprised of RF module, control module, buffer module, transmission module and a data acquisition routine. RF module is designed as a single-circuit board to facilitate for replacement, GNSS signal is converted to IF digital signal by filtering, amplifying, down conversion and sampling in the RF module; Programmable logic device is used in control module, so it is flexible and upgradeable. The entire data flow control is completed by programmable logic device; USB2.0 controller is used in transmission module, which provides high speed performance to meet the requirement of GNSS IF signal. It is used to transmit the IF digital signal to the USB bus; Data acquisition routine running on the computer collects GNSS IF digital signal from the USB bus and stores it in the computers storage medium.
