USB GPS Receiver

GPS image

The USB GPS receiver has a low power consumption. It is built with SiRF III GPS Chips architecture. It is very suitable for GIS application.

Features:

  • Builds on SiRFstarIII chipset with embedded ARM7TDMI CPU available for customized applications in firmware.
  • 20 parallel satellite-tracking channels for fast acquisition and reacquisition.
  • 200,000 effective correlators for fast TTFF (Time-To-Fast-Fix), and Extremely fast TTFF’s at low signal level.
  • Built-in hardware Tracking Loop Processor WAAS/EGNOS Demodulator support.
  • Built-in repeatable and rechargeable Lithium-ion battery for Time- to- First-Fix (TTFF).
  • Support NMEA 0183 v3.0 data protocol.
  • Enhanced algorithms provide superior navigation performance in urban, canyon and foliage environments.
  • For Car Navigation, Marine Navigation Fleet Management,AVL and Location-Based Services, Auto Pilot, Personal Navigation or touring devices,Tracking devices/systems and Mapping devices application.
