1.1 1.1 1.1 1.1 Introduction Introduction Introduction Introduction The GPS-622F a highly integrated smart GPS module w ith a ceramic GPS patch antenna. The antenna is connected to the module via an LNA. The module is with 54 channel acquisition engine and 14 channel track engine, which be capable of receiving signals from up to 68 GPS satellites and transferring them into the precise position and tim ing information that can be read over UART port. Small size and high-end GPS functionality are at lo w power consumption, the LVTTL-level signal interface is provided on the interface connector, supply voltage of 3V~5.5V is supported. The compact 22mm x 22mm form factor allows it to be used in many applications. The smart GPS antenna module is available as an off-the-shelf component, 100% tested. The smart GPS antenna module can be offered for OEM applicati ons with the versatile adaptation in form and connection. Additionally, the antenna can be tuned to the final systems’ circumstances. 1.2 Features 1.2 Features 1.2 Features 1.2 Features /square4 68 Channel GPS L1 C/A Code /square4 Perform 8 million time-frequency hypothesis testing per second /square4 65 Channel GPS L1 C/A Code /square4 Perform 8 million time-frequency hypothesis testing per second /square4 Open sky hot start 1 sec, Open sky cold start 29 se c /square4 Signal detection better than -165dBm /square4 Multipath detection and suppression /square4 Accuracy 2.5m CEP /square4 Maximum update rate 20Hz /square4 Tracking current ~33Ma /square4 Supports external active antenna 1.3 Applications 1.3 Applications 1.3 Applications 1.3 Applications /square4 Automotive and Marine Navigation /square4 Automotive Navigator Tracking /square4 Emergency Locator /square4 Personal Positioning

Particularly difficult is close-in multipath in which the reflected secondary signals arrive only slightly later (within about 100 nanoseconds) than does the direct-path signal, having been reflected from objects only a short distance from the receiver antenna. GPS-622F deploys the advanced multi-path detection and suppression algorithm to reduce multipath errors, the GPS signals themselves can be designed to provide inherent resistance to multipath errors
