The Garmin GLO is a portable GPS and GLONASS receiver that brings industry-leading Garmin GPS technology to mobile devices. GLO wirelessly connects to Apple and Android devices via Bluetooth technology. It offers up to 12 hours of battery life and a position update rate of up to 10 times per second (update rate may be limited by the host device). This is approximately 10 times faster than the internal GPS receivers of most mobile devices. GLO is approved by Apple for use with its products.
When using both GPS and GLONASS satellites, the time it takes for the receiver to "lock on' to a position is, on average, approximately 20 percent faster than using GPS alone. Furthermore, when using both GPS and GLONASS, the receiver has access to 24 more satellites than using GPS alone. GLO works seamlessly with a variety of apps, including Garmin StreetPilot which provides turn-by-turn instructions.
