Overview:
AM-318 is an easy to use, ultra-high performance, low power GPS smart antenna module with patch antenna for handheld/AVL applications.
The built-in SiRFstarIII chip and our experienced design provide fast acquisitions and excellent tracking performance. |
Applications:
- Personal navigation devices
- Child/elderly/personal locator and security system
- GPS clock and digital camera
- Automatic vehicle location
Features:
- Ultra-small (18x21 mm) and easy to use with built-in patch antenna, backup battery, and 5 soldering pins
- Based on SiRF's GSC3f low power single chip
- High performance: -159dBm tracking sensitivity
- Low power: 40mA at continuous tracking
- Push to fix reduces power by as much as 98%.
- SBAS (WAAS and EGNOS) support
- Fully EMI shielded
- Industrial operating temperature range: -40 ~ 85°C
