GPS systems require that at least 3 satellites be visible. Most classrooms do not have adequate exposure to 3 or more satellites. Graymark's Re-Radiating System delivers satellite signals from the school's roof to the classroom, enabling GPS receivers to function properly. If a notebook computer is available, students can perform outdoor navigation exercises.
