SkyNav
GB10
Ultra Fast
TTFF and All in One GPS Receiver Board
General
Description
The SkyNav GM11 is a 12
channel continuous tracking GPS receiver optimized for high sensitivity and
low cost applications. The GPS signal is applied to the antenna input of the
module, and a complete serial data message with position, velocity and time
information is presented at the serial interface.
The GM11 contains a low noise
amplifier for passive antenna operation, RF down converter, baseband
processor, flash memory and navigation software. The module provides
excellent navigation performance under static or dynamic conditions in areas
with limited sky view like urban canyons, fast TTFF for weak signal
operation. Power saving mode make this product suitable for handheld and
battery-operated devices.
