Abstract

"PSEUDóLITO, RECEPTOR, BANCO DE RECEPTORES DE GPS DE N-CANAIS E CONVERSORES DE FREQuêNCIA ANEXOS E PROCESSO COMPUTACIONAL PARA DETERMINAR TODAS AS AMBIGuIDADES DE FASE DE PORTADORA PARA CADA SINAL DE PSEUDóLITO RECEBIDO". Aparelho e método para resolver ambig³idades de integridade na determinação de posição. Um modo de realização da invenção inclui um sistema de referência, aumentado com pseudólitos de múltiplas freq³ências usando uma implementação de GPS de diferencial de fase de portadora, e um sistema móvel. Em um modo de realização, os componentes do sistema de referência incluem um ou mais pseudólitos de múltiplas freq³ências, um ou mais receptores de referência de múltiplas freq³ências, um enlace de dados separado ou construido nos pseudólitos, e as antenas associadas a cada um destes elementos. Os componentes do sistema de referência podem ser estacionários. O sistema móvel pode incluir um receptor de múltiplas freq³ências e suas antenas associadas. Devido ao sistema móvel poder receber informação passivamente, um numero ilimitado de sistemas móveis pode ser incluido em qualquer dado modo de realização da invenção. Um pseudólito de múltiplas freq³ências usa uma única fonte de freq³ência para sintetizar todas as múltiplas freq³ências de portadora e todos os múltiplos sinais de faixa base modulados sobre freq³ências de portadora para transmissão.
