GPS Trainer

 

 

The GPS Trainer Model 7524 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 GPS10 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 signaloperation. Power saving mode make this product suitable forhandheld and battery-operated devices.
