Abstract

uso de dados de sensor inércial para melhorar posicionamento de estação móvel. uma implementação de um sistema e método a utilização de dados de sensor inercial para melhorar o posicionamento da estação móvel é provida. muitos dispositivos móveis incluem um sensor inercial. estas medições de inércia tipicamente produzem medições de inércia de baixa resolução, que podem ser utilizadas para gerar um valor de incerteza e/ou para selecionar um modelo de posicionamento do filtro. em algumas modalidades, este valor de incerteza é utilizando como um sinal de entrada de ruído de processo em um filtro de kalman ou filtro semelhante. em algumas modalidades, uma estimativa de posição é selecionada a partir de múltiplos modelos de filtro de posição de navegação operando simultaneamente, cada um calculando uma estimativa de posição separada. nestas modalidades, a estimativa de posição é selecionada com base no valor de incerteza ou com base em uma outra característica das medições de inércia.
