A Handheld Global Positioning System with Compass and VHF Radio Transceiver

GPS is already widely used today. Still, a device that has a multifunction VHF radio, GPS, Compass, temperature, humidity, time display, and location tracker is not yet accessible in one single device. This study aims to construct a multipurpose instrument that is portable and easy to carry-handheld machine. The device can approximate the general location of the person who’s holding the proto through the use of a Cell SMS notification. It is capable of two-way radio communication with a channel ranges from 134MHz-174MHz with an average 40.1dB result to 20 trials of the said channel. The study concluded with the successful creation of two similar multifunction devices.
