Development of a prototype of a compact navigation device

Our engineers have developed a prototype of a compact navigation device which brings the user back to the starting point or a pre-marked location in a coordinate system. The product’s distinguishing features include: low power consumption, ease of use and a low manufacturing cost (about $30 in a batch of 10,000). The device is controlled with two buttons. Information is displayed on a black-and-white LCD screen: cardinal points, direction of movement and distance to a specified point.

The purpose of this development for the customer is the creation of a simple and affordable product for retirees, outdoor enthusiasts, tourists and mushroom pickers for whom the functionality of modern navigation devices is excessive.

Key features of a personal GPS navigator

  • Accurate operation
  • Compact size: it is designed to fit the user’s palm; it can be worn on a string or a bracelet
  • Intuitive use: two control buttons; it needs no preset and uses no digital maps
  • High-capacity battery and low power consumption: automatic shutdown, supply of power to the compass only at the time of measurement, several days of battery life, saving marked points in case of battery replacement 
  • Ergonomic design, enclosure design based on manufacturing technologies
