Nemerix SA has further extended its technology leadership in the GPS and AGPS markets by announcing a hosted GPS baseband processor which achieves indoor sensitivity as low as -158 dBm while consuming just 40mW.

The NJ2020 is available in a 6x6mm BGA package and utilizes the memory and processor resources already available on a host platform such as a PDA or mobile phone.

This architecture allows for fast integration and reduced system costs as resources on the host are often more readily available. The NJ2020 is air interface agnostic, consuming 40mW at 1Hz fixes and less than 7 MIPs with no realtime requirements from the host when paired with the Nemerix NJ1006A GPS RF IC and Nemerix Navigation Software.

The NJ2020 provides a simple path for integrating GPS/AGPS functionality into an end product. It achieves its -158 dBm sensitivity in autonomous or assisted mode across various wide area networks (GSM, WCDMA, CDMA, and iDen networks). The total solution footprint when utilizing Nemerix’s GPS RF NJ1006A is less than 90sq. mm. Nemerix’s NJ2020 also places no real time demands on the host CPU and permits simple interfacing via UART, SPI, or I2C. Source code for Nemerix Navigation Software is also provided permitting faster time to market.
