摘要： AltBOC-modulated satellite navigation signals transmitted in the two partial bands E5a and E5b of the so-called E5 frequency band are received using a common antenna (19) and thereafter are processed separately in an analog manner in the HF front-end in two physically different incoming signal paths for the two partial bands and then digitized and coherently summed to form a complete digital E5 band signal, which is fed to a digital signal processor, in which code acquisition and code tracking are performed using PRN reference code sequences produced in the receiver and tracking of the carrier phase is performed and raw data for the final navigation calculation are determined therefrom. From the PRN reference code sequences produced in the receiver, a PRN code calibration signal is produced, which is up-converted to the carrier frequency and then coupled into the HF front-end as a pseudo satellite navigation signal by means of a directional coupler (20) directly after the antenna, which pseudo satellite navigation signal is also tracked in the digital signal processor as an addition signal, which makes it possible to calibrate the HF front-end for the two partial bands during the normal satellite navigation signal reception.For application with Galileo satellite navigation receivers.
