Abstract The Global Positioning System is a navigation system designed for military use, but subsequently made freely available. It has since been utilized in a wide variety of ways including science, transportation, surveying, financial services, and recreational use. However, the changing and growing demand quickly make it obsolete, and some ways have been proposed to update the system, varying ineffectiveness, complexity, time restrictions, and cost. Introduction Global Positioning System (GPS) is a system comprised of satellites capable of broadcasting certain signals designed to provide precise time and location and used primarily for navigation in both the private and the military sectors. It also shows promising perspectives in the fields of robotics, unmanned vehicle navigation, cartography, emergency services, and a wide variety of civil recreational use. However, since its launch in 1972 both the changes in demand and technological progress have established the need for updates, as the GPS is prone to a variety of errors due to its fundamental principles of operation. This paper aims at assessing the range of flaws incorporated into the system, reviewing the current state of updating the system, and outlining the possible directions for further improvements. The reason for the scope of the paper is the success the system has had so far, the possibilities it offers in a multitude of fields and the impressive list of achievements already made possible by the implementation of GPS, which is properly credited with several awards and can not be dismissed easily. The eradication of errors and flaws characteristic for the current state of the system may not only increase performance in already established fields of use but add new possibilities. Overview of the Technology A Brief History of the System The Global Positioning System was conceived in the 1970s and was essentially a continuation of the earlier works of a similar kind. Its two primary concepts – the constellation of satellites orbiting the Earth to provide constant exposure and the analysis of radio signals from several sources for navigation purposes were borrowed from the TRANSIT military satellite navigation system and the ground-based OMEGA radio navigation systems, respectively [1]. Both systems were fully operational by 1973 and were proven successful. The GPS was initially intended for military use, with its navigational capabilities directed towards operating intercontinental ballistic missiles, strategic bombers, and submarines carrying a nuclear arsenal. The tension between the USA and the Soviet Union helped to accept the budget of the project, which comprised several billion dollars. However, the system was later given a dual-use status, meaning that it would be available for the civilian as well as military use. The cause most commonly cited is the incident that took place in 1983, when the stray civilian airliner has unintentionally breached the Soviet airspace and was shot down by an interceptor, resulting in 269 deaths. This illustrated the dire need for a readily available navigation system and prompted Ronald Reagan to issue a directive to make GPS publicly accessible as soon as it becomes operational. However, the technology became available that same year, while the full operational capability was announced only in 1995. The dual-use policy mea
