| LEA-5A u-blox 5 ROM-based GPS Module - GALILEO-ready |
|
Powered by the 50-channel u-blox 5 positioning engine, the LEA-5A module is ideal for applications that require excellent GPS performance without the need for weak signal acquisition. This is typically the case in applications that use an active external antenna, such as u-blox' ANN high performance GPS antenna. The LEA-5A module is ROM-based, which cuts costs by replacing a more costly Flash EPROM by the internal read-only memory of the module's 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. 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.
