Abstract
A multi-standard single chip integrated within a multi-standard mobile device concurrently receives multi-standard radio frequency signals by corresponding two or more integrated radios. The multi-standard single chip generates full GNSS measurement comprising pseudo-range information using the received radio frequency signals. The multi-standard single chip comprises a GNSS radio and multiple non-GNSS radios such as Bluetooth. The full GNSS measurement is generated using GNSS radio frequency signals received by the integrated GNSS radio and communicated over, for example, Bluetooth radio. GNSS satellite reference information embedded in radio frequency signals received by the integrated non-GNSS radios is extracted to assist the full GNSS measurement. A full GNSS navigation solution for the multi-standard mobile device is generated internally to and/or externally to the multi-standard single chip depending on the location of a navigation engine. The generation of the full GNSS measurement is independent of a host processor within the multi-standard mobile device.
