BU-353N5 USB Interface G Mouse GPS Receiver SiRF Star IV Module(Black)About The ProductThe BU-353N5 is a USB GPS receiver that features a highly sensitive, low power consumption chipset in a ultra compact form factor. The BU-353N5 is powered by a SiRF Star IV GPS chipset, and will provide you with superior performance in urban canyons, and in dense foliage. With the SiRF CGEE (Client Generated Extended Ephemeris) technology, has the capability of predicting satellite positions for up to 3 days in advance,and will deliver a CGEE-start time of less than 15 seconds under most conditions without any network assistance. The BU-353N5 MicroPower mode allows the receiver to stay in a hot start-like condition almost continuously while consuming very little power.Features1. SiRF Star IV high performance GPS Chipset 2.
