The LEA-4S module combines high sensitivity, exceptionally low power consumption and a USB port in a small module measuring just 17 x 22 mm. Its -158 dBm tracking sensitivity extends positioning coverage into places where GPS was not possible before and enables solutions using smaller or covert antennas. To reduce costs, the Flash EPROM has been replaced by an internal read-only memory (ROM) in the GPS Baseband chip from which SuperSense runs.
