  • Adding multi-system functionalities to legacy navigation satellite system receivers
    Patent number: 8860610
    Abstract: Methods and apparatuses are disclosed for enabling a satellite-based navigation signal receiver to support multiple types of global navigation satellite systems (GNSS). A legacy GNSS receiver can support a plurality of GNSS types by software upgrade and with a new/modified radio frequency (RF) chip. There is no need to completely redesign a navigation host chip to support the multiple GNSS types. This invention offers a cost-efficient multi-GNSS solution without sacrificing the navigation performance. A GNSS baseband controller controls synchronization of measurement time for digitized data along a first signal processing path for a legacy GNSS signal and a second signal processing path for a non-legacy GNSS signal.
