Nemerix SA unveiled a hosted GPS baseband processor that can achieve an indoor sensitivity as low as -158dBm while consuming 40mW. The NJ2020 processor utilizes the memory and processor resources already available on a host platform such as a PDA or mobile phone. According to the company, 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 7MIPs with no realtime requirements from the host when paired with Nemerix's NJ1006A GPS RF IC and Navigation Software.

The new baseband IC provides a simple path for integrating GPS/AGPS functionality into an end product. It achieves the -158dBm sensitivity in autonomous or assisted mode across various wide area networks (GSM, W-CDMA, CDMA and iDen networks), places no real time demands on the host CPU, and permits simple interfacing via UART, SPI or I?C.

The NJ2020 is available in a 6-by-6mm BGA package.
