LEA-5S

u-blox 5 ROM-based GPS Module

 LEA-5S GPS Module

RoHS compliant
17 x 22.4 mm

Powered by the 50-channel u-blox 5 positioning engine, the LEA-5S is ideal for applications that require a high performance GPS receiver and fast weak signal acquisition performance. This cost-efficient module enables solutions that use smaller or covert antennas thanks to its built-in -160 dBm built-in SuperSense® Indoor GPS technology. To reduce costs, the Flash EPROM has been replaced by an internal read-only memory (ROM) in the GPS Baseband chip.

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.
