NemeriX推出更高敏感度的主GPS/AGPS產品
(技術新聞, 2005年9月21日)
|
NemeriX SA recently released a hosted GPS baseband processor that achieves indoor sensitivity as low as -158 dBm while consuming just 40 mW. The NJ2020 is available in a 6 x 6 mm 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 40 mW at 1 Hz fixes and < 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 WANs (GSM, WCDMA, CDMA, and iDen). The total solution footprint when utilizing NemeriX's GPS RF NJ1006A is less than 90 sq. 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.
