The industry's first single-chip A-GPS solution has been released by Sequoia Technology, making location-based functionality easier to integrate into mobile terminals, including asset and offender tracking, personal location and other handheld terminals. The SiRF GSC3 and GSC3f from Sequoia save board space by combining the functions of several previously separate components. The two devices are the first in the industry to pack a complete autonomous GPS and A-GPS (assisted GPS) digital baseband processor, an embedded CPU and an RF front end into a single package measuring just 7 x 10mm.
Additionally, the GSC3f includes 4Mbit of Flash memory.
The GPS receivers manufactured by SiRF Technology Inc also enable end users to determine their geographical location in a wider range of environments.
Whereas traditional GPS receivers need a clear view of the sky to capture satellite signals, the GSC3 and GSC3f also operate within buildings, in urban canyons or under dense foliage.
This is due to their outstanding signal sensitivity of -158dBm.
Based on the existing SiRFstarIII architecture, the new devices replicate the proven performance and low power consumption of SiRF's earlier multichip solution.
SiRFstarIII allows for faster and deeper searching of GPS signals by implementing the equivalent of more than 200,000 correlations.
This increases both signal sensitivity and speed compared to traditional systems using several hundred or a few thousand correlators.
As a result, the GSC3 and GSC3f receivers achieve a remarkably short TTFF (time to first fix) of just 1s in outdoor environments, with assistance from the cellular network.
In case locally available networks do not support GPS, location fixes can be obtained from GPS satellite signals alone, using the SiRFSoft software package.
