Features

Multi-GNSS, Concurrent reception of GPS and GLONASS

The best positioning accuracy and smoothest ground tracking
Improved of robustness thanks to concurrent reception of GPS and GLONASS signals
Supports concurrent GPS, GLONASS, SBAS and QZSS

Receivable Galileo E1B/E1C

Galileo E1B and E1C signals receivable (ref. "Galileo OS SIS ICD Issue 1 Revision 1 September 2010")

Improved positioning rate with the world’s best-in-class number of acquired satellites

Twice the number of satellites in view than with GPS-only positioning thanks to Multi-GNSS
Improved success rate of positioning by receiving much more satellites even in urban canyons
Improved positioning accuracy in harsh environments where position jumps and misalignments occur with GPS-only positioning

Fast TTFF

Hot start: <1 sec

High Positioning Rate

Configurable position output update rate up to 10Hz (10 times per sec.)

Improved Noise Tolerance

Reduces effects of internal and external noise

Android™ driver and API

Furuno can provide Android driver and API, which can be used with Furuno's GNSS chip/module for Android application developers.
Android driver may help to reduce the development cost to install the GNSS chip/module in the navigation devices or the automotive devices based on Android.
