Abstract

mitigação de impacto de fase de código de filtro rejeita-faixa. técnicas são fornecidas para a utilização de filtros rejeita-faixa para superar o bloqueio de banda estreita. um método de exemplo para determinar um alcance para um veículo de satélite com um receptor inclui receber um sinal a partir do veículo de satélite, determinar uma ou mais configurações de filtro rejeita-faixa, determinar um código de ruído pseudo-aleatório e uma frequência doppler associada ao sinal, determinar um valor de correção de fase de código com base pelo menos na uma ou mais configurações de filtro rejeita-faixa, no código de ruído pseudo-aleatório, e na frequência doppler, e calcular o alcance para o veículo de satélite com base, pelo menos em parte, no sinal e no valor de correção de fase de código.band-reject filter code phase impact mitigation. Techniques are provided for using band-reject filters to overcome narrowband blocking. An example method for determining a range for a satellite vehicle with a receiver includes receiving a signal from the satellite vehicle, determining one or more band-reject filter settings, determining a pseudorandom noise code and a doppler frequency. associated with the signal, determine a code phase correction value based on at least one or more band-reject filter settings, the pseudorandom noise code, and the doppler frequency, and calculate the range for the satellite vehicle based, at least in part, on the signal and code phase correction value.
