uN3010 TECHNOLOGY Overview

The Atheros uN3010 is a high-performance GPS solution, consisting of the tiny CMOS uN3010 GPS IC teamed with the powerful ORION V2.x multi-mode navigation software. The uN3010 IC is a highly-integrated GPS RECEIVER comprised of a single-conversion RF front-end and a GPS baseband processor combined into a single die. The L1 RF front-end includes an on-chip low noise amplifier (LNA), and a configurable phase-locked loop (PLL) that supports six (6) TCXO frequencies. The uN3010 provides 20- channel GPS operation and is based on an optimized 16-bit DSP with a compact, embedded real-time operating SYSTEM (RTOS). The ORION V2.x Software is a powerful GPS navigation software PACKAGE that supports hosted, autonomous, assisted-conventional, and single-fix Assisted-GPS (AGPS) modes while exceeding all 3GPP and other AGPS performance requirements. ORION V2.x also provides ADVANCED acquisition algorithms to efficiently find weak GPS signals by utilizing the company's third-generation search engine, and advanced tracking loops. These features allow ORION to quickly adapt to the DYNAMIC conditions found in harsh urban canyons. The Atheros uN3010 solution can operate in stand-alone GPS mode (NMEA, PVT out) or host-based mode where the position is calculated by the host processor or network. In the host-based configuration, the ORION V2.x software has been designed to minimize burden on the host processor. With the uN3010, Atheros offers one of the highest performance, most cost-effective GPS solutions on the market today which also delivers on the size, power and cost requirements so important to our customers.
