GPS Receiver Modules GN-80
Miniature high-performance GPS receivers have been greatly expanding the application field for GPS receivers in the last few years. Leading the way in this world trend, Furuno has developed a new all-purpose GPS receiver, model GN80, with greatly improved performance characteristics and incredibly low power consumption.
Higher sensitivity and faster TTFF has been realized thanks to newly developed signal processing technology and high-speed search engines integrated into each of the GN80's 16 channels.
This new GPS receiver, Furuno's 5th generation since 1992, will surely provide users with optimum solutions in various applications.
Characteristics
- Faster TTFF: 46 seconds typical in Cold Start has been realized thanks to high-speed search engines integrated into each channel
- Significant improvement in higher sensitivity - 8dB better than our former Model GN-79
- Miniature and lightweight - 40% less than our former Model GN-79
- Low power consumption - 48mA while tracking satellites (1/3 less than previous Model GN-79) without sacrificing performance
- Selection of mounting methods including Vertical and Horizontal
mount types
- Selection of various antenna connectors
- WAAS ready available as an option
- Antenna detection circuitry incorporated
- 1PPS output synchronized with UTC
- Flash ROM containing user application can be integrated into Digital ASIC (optional)
