The 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.
