Sažetak
In the introduction, described how in the past 30 years resized dimensions of GPS receivers from of large size instruments to small size in mobile phones. In the same time also the significantly increased the accuracy of the GPS receivers, but still not solved all the problems. For example, problems when receivers cannot receive GPS signals which broadcast the GPS satellites. In such cases, can be used inertial systems (gyroscopes and accelerometers) that currently have a relatively low accuracy. In order to solve these problems the British Ministry of Defence has decided to improve it. Therefore, they financed projects for construction a more accurate atomic interferometric gyroscopes and atomic accelerometers, i.e. the atomic inertial devices. To do that they used lower the temperature by three pairs of lasers in mutually opposite directions as proposed in the discovery for which the Nobel Prize in Physics in 1997. In addition, they are using Sagnac's and Raman's effects.
