According to Skaloud [1999], the inertial sensor errors are composed of long term errors (low frequency components) and short term errors (high frequency components). Therefore, a conceptual plot of the frequency spectrum of the inertial sensor errors in the measurements can be illustrated as in Figure (1).

German government makes funds available for Galileo development work
The German federal government will provide funds to the tune of 2.5 million Euros for research and development work in Rostock on the European satellitebased navigation system Galileo.
In the course of a visit to the Rostockbased technology company RST, Wolfgang Tiefensee, the Federal Minister responsible for promoting the industries of the eastern federal states that used to make up the German Democratic Republic, said that the groundwork R&D in the field of aerospace technology carried out by companies in Mecklenburg West-Pomerania was of an outstanding quality. Substantial funds would now be invested in Galileo application research, he added.
Within the context of research undertaken by RST, four transmitters will be set up in the port of Rostock capable of giving off Galileo signals. During the test phase the signals, which allow the receiver to pinpoint the position of the sender exactly, will be picked up by a ship of the ferry line Scandlines. www.heise.de

Siemens wireless modules XT75 and XT65
In December 2006, the Siemens Communications Group, Munich will bring to market two new modules for tracking and navigation applications: the XT75 and the XT65. Both modules contain a GPS receiver that allows global positioning, and EDGE or GPRS technology for transmitting data to a mobile device. The modules are based on JavaT and have quadband capability, which means they can be used in all GSM mobile networks worldwide.
