LEA-5H General Description

With the integrated u-blox 5 positioning engine containing 50 channels, the LEA-5H module provides unparalleled acquisition and navigation performance. A dedicated acquisition engine with over 1 million correlators is capable of doing simultaneous searches across the entire time/frequency space to find satellites instantly, even under difficult signal conditions, providing Time To First Fix (TTFF) of under 1 second and 160 dBm acquisition sensitivity. Once the signals are acquired, they are passed to the tracking engine. With innovative solutions to suppress jamming sources and mitigate multipath effects, it provides excellent navigation performance with low power consumption in most challenging indoor and outdoor locations.

The built-in Flash EPROM provides space to store userspecific configuration settings and enables future firmware updates, e.g. to process Galileo signals when Galileo is put in operation. The combination of these features makes this module suitable for a broad spectrum of GPS products whose key requirements include high sensitivity, low power consumption and small size.

LEA-5H Features

• 32 channel acquisition engine
• 18 channel tracking engine for GPS + Galileo
• Supports A-GPS solutions including
• AssistNow® Online and Offline
