LEA-5H

u-blox 5 Programmable GPS Module

GALILEO-ready

17 x 22.4 mm

Powered by the 50-channel u-blox 5 positioning engine, the LEA-5H module provides unparalleled acquisition and navigation performance. The LEA-5H is the optimal choice for applications requiring a high performance GPS receiver and fast weak signal acquisition capability. It enables solutions using smaller or covert antennas thanks to the built-in SuperSense Indoor GPS technology. Additionally, the LEA-5H comes with a Flash EPROM, allowing firmware updates.

u-blox 5's dedicated acquisition engine, which boasts over 1 million correlators, is capable of doing massive parallel time/frequency space searches, providing a Time To First Fix (TTFF) of under 1 second. The engine's -160 dBm acquisition sensitivity enables acquisition and tracking performance in the harshest signal environments, including weak signal environments such as urban canyons or covert locations. Once the GPS signals are acquired, the acquisition engine passes them to a dedicated tracking engine and switches off. This enables efficient power management without compromising on performance. Innovative technologies suppress jamming sources and mitigate multipath effects, giving u-blox 5 GPS receivers excellent navigation performance in the most challenging environments.
