u-blox 5 ROM-based GPS receiver module The LEA-5S is a stand-alone, compact GPS receiver module designed to allow easy, straightforward migration from its LEA-4S and LEA-4A predecessors and featuring u-blox' KickStart weak signal acquisition technology. Its built-in antenna supervisor makes LEA-5S ideal for solutions that use small active or passive antennas. u-blox KickStart provides accelerated startup at weak signals, and our featured SuperSense® Indoor GPS is capable of acquiring and tracking even extremely weak signals. This offers unmatched tracking and acquisition performance in harsh signal environments such as parking lots and dense urban environments. The module's architecture further ensures that costs are minimal by replacing costly Flash EPROM with an internal Read-Only Memory (ROM) in the GPS baseband chip.
