array of mobile devices, all featuring a high level
of design and integration ease.
uN3010 Technology Overview
The Atheros uN3010 is a high-performance GPS
solution, consisting of the CMOS uN3010 GPS IC
teamed with the powerful ORION™
v2.2
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 v2.2
Software is a powerful GPS navigation
software package that supports autonomous,
assisted-conventional, and single-fix Assisted-GPS
(AGPS) modes while exceeding 3GPP AGPS performance
requirements. ORION v2.2
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.
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.
