Antaris4 Single-chip Gps Receiver - Atmel Corporation

The ATR0630 is a low-power, single-chip GPs receiver, especially designed to meet the requirements of mobile applications. It is based on Atmels ANTARIS4 technology and inte- grates an Rf Front-End filtering, and a baseband processor in a single, tiny 7 mm 10 mm 96 pin BGA package. Providing excellent RF performance with low noise figure and low power consumption. Due to the fully integrated design, just an RF SAW Filter a GPs XTAL (no TCXO) and blocking capacitors are required to realize a stand-alone GPs functionality. The ATR0630 includes a complete GPs firmware, licensed from u-blox AG, which performs the GPs operation, including tracking, acquisition, navigation and position data output. For normal PVT (Position/Velocity/Time) applications, there is no need for external Flash- or ROM-memory. The firmware supports e.g. the NMEA protocol (2.1 and 2.3), a binary protocol for PVT data, configuration and debugging, the RTCM protocol for DGPS, SBAS (WAAS, EGNOS and MSAS) and A-GPS (aiding). It is also possible to store the configuration settings in an optional external EEPROM Due to the integrated ARM7TDMI processor and an intelligent Radio architecture, the ATR0630 operates in a complete autonomous mode, utilizing on chip AGC in closed loop operation. For maximum performance, we recommend to use the ATR0630 together with a low noise Amplifier (e.g. ATR0610 . The ATR0630 supports assisted GPs By ATMEL Corporation
