SkyNav GM10
Ultra Fast TTFF and Low Power GPS Receiver Module
General Description
The SkyNav GM10 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 GM10 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.
