Acquisition capabilities of GNSS Scintillation Receiver GSV4004A/GSV4004B
Last modified at May 8th, 2022, 11:30 GMT
Description
The instrument collects the GNSS signals from the line-of-sight satellites and tracks their numerical counterparts. The RF front-end down-converts the input signal to a predefined Intermediate Frequency (IF) prior to its sampling and quantization. Eventually, it provides prompt In-Phase and Quadrature samples which can be used to estimate the signal Amplitude variations, while the signal Phase variation can be derived through the output of the loop filter in charge of tracking the IF carrier. The GSV4004A/GSV4004B provides the raw GPSsamples at 50 Hz for all the visible GPS satellites (up to 10) for signal types L1-C/A and L2-P, and up to 3 SBAS-GEO satellites.
