The BU-353-S4’s slim profile housing is completely water resistant and incorporates an active patch antenna for the highest level of GPS accuracy. The BU-353-S4's MicroPower mode allows the receiver to stay in a hot start-like condition almost continuously while consuming very little power. 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-353-S4 is powered by a SiRF Star IV GPS chipset, and will provide you with superior performance in urban canyons, and in dense foliage. The BU-353-S4 is a USB GPS receiver that features a highly sensitive, low power consumption chipset in a ultra compact form factor.
