08 September 2006 – Siemens researchers have developed simulation software that can test the precision of Galileo, Europe’s satellite system of the future, even though not all of the satellites are yet in position.

Developed at Siemens’ Roke Manor research centre in southern England, the software is based on the signals to be transmitted by Galileo and includes GPS. This makes it possible to calculate whether a receiver can also detect navigation signals under unfavourable conditions. By analysing blueprint plans and ground plans of buildings as well as satellite and aerial photographs of cities, the software accurately forecasts signal strength and expected measurement errors.

Plans call for the simulation to be integrated into a system that is now being developed by experts at Siemens Communications, in Berlin. With the help of the Galileo satellites and mobile communications base stations, such as GSM and UMTS, the system will be able to precisely determine the position of mobile devices. This, in turn, will make it possible to offer attractively priced navigation services for use with mobile phones.
