u-blox AG has launched a pair of GPS modules called u-blox 5 that is based on its fifth-generation positioning engine.

When the blox-5 chip and module are coupled with the company's AssistNow A-GPS service, they are capable of acquiring satellites in less than one second, according to the company.

The module is housed in the industry-standard LEA form factor for several applications, including automotive, consumer and industrial.

u-blox 5 modules employ a 50-channel GPS architecture with more than 1 million correlators and separate acquisition and tracking engines, capable of massively parallel searches. The LEA-5 modules deliver a -160dBm acquisition and tracking sensitivity.

The LEA-5 GPS module series is Pb-free and has an industrial temperature range of -40C to 85C. Its small form factor and SMT pads allow for fully automatic assembly processes with standard pick-and-place equipment and reflow soldering, enabling cost-efficient, high-volume production.

The LEA-5H GPS module comes with flash EPROM that enables easy firmware upgrades and set-up configuration saving options. The ROM-based LEA-5S offers further cost efficiencies. Both modules feature u-blox' OMA SUPL compliant A-GPS interface and support AssistNow Online and AssistNow Offline A-GPS services.
