Garmin GLO Portable GPS and GLONASS Receiver
July 11, 2012 - Garmin's new compact GLO is the first wireless receiver that uses both the familiar GPS signals, and the relatively new GLONASS constellation of satellites operated by the Russians. Using both satnav systems gives the GLO 24 more satellites than using GPS alone, so it will lock on quicker and operate in difficult environments where GPS-only signals may be blocked by terrain.
The GLO uses Bluetooth to wirelessly connect to tablet devices like the iPad. Garmin says internal battery life for the GLO is about 12 hours. Because it uses both satnav constellations, average time to "lock on" is 20 percent quicker than with GPS only, and GLO can output a position update 10 times each second compared to the once per second rate for basic GPS receivers.
Garmin is offering GLO as a basic nav receiver with a list price of $99. An aviation version that includes a mount, a power cable to backup the internal battery, and a six-month subscription to Garmin Pilot, Garmin's aviation app for Apple and Android devices, is priced at $129. Street prices should be lower.
GLO for Aviation is ready for immediate delivery and will be available at AirVenture Oshkosh starting on July 23. For more information see the Garmin website.
