Confused about your GPS not working well in urban or outsides under only one or a few satellite module? Then you should not miss our new Grove-GPS (Air530). It’s a high-performance, highly integrated multi-mode satellite positioning and navigation module to use with Arduino. It supports GPS / Beidou / Glonass / Galileo / QZSS / SBAS, which makes it suitable for GNSS positioning applications such as car navigation, smart wear, and drone. Meanwhile, this module is capable of receiving more than 6 satellites at the same time and is able to work excellently even if there's a very bad signal.
Feature
- Highly Integrated Multi-mode Satellite Positioning: Multi-mode satellite positioning & navigation and support more than 6 satellites at the same time
- High precision Positioning: Positioning error within 10 meters,and the position still quickly and accurately under the condition of bad signal
- The Integrated Design of RF Baseband: Adopt the integrated design of RF baseband, which integrates DC/DC, LDO, LNA, RF front-end, baseband processing, 32-bit RISC based chip, RAM, FLASH storage, RTC, and power management functions
- Low Power Consumption: Low power consumption at only 31uA
- High Compatibility: Compatible hard/soft interface for other modules
