Leadtek LR9450 GPS Smart Antenna

The Leadtek LR9450 GPS Smart Antenna is a highly sensitive and compact GPS receiver featuring the SiRF StarIII GSC3f series chipset with 20-channel tracking capability. Measuring 60x60x19 mm and weighing 80g, this waterproof GPS mouse includes a magnetic mounting base for secure vehicle-top placement and features a non-slip underneath surface. The device delivers fast positioning with time-to-first-fix of 42 seconds (cold start), 35 seconds (warm start), and 1 second (hot start), with a reacquisition time of just 0.1 seconds. It provides autonomous horizontal position accuracy of less than 2.5 meters, enhanced to less than 2.0 meters with SBAS (WAAS and EGNOS) support. The antenna operates on L1 frequency (1575.42 MHz) with tracking sensitivity of -159 dBm and acquisition sensitivity of -142 dBm. It connects via RS232 interface with RJ11 connector and 1.5-meter cable, supporting NMEA-0183 protocol at 4800 bps default baud rate (SiRF Binary also available). The unit operates from -30°C to +70°C, supports altitudes up to 18,000 meters and velocities up to 515 meters/second, and runs on 5VDC power with 370mW consumption (75mA current draw). Additional features include an RF metal shield for noise immunity, built-in high gain amplifier and bandpass filter, GPS status LED indicator, and RoHS compliance for environmental standards.
