Eurasia Announces Launch of Miranda GPS System

The United Kingdom of Eurasia announced the initial launch of their Miranda Global Positioning Satellite System early this morning, with the first satellite just reaching its desire geosynchronous orbit position.

This is the first of thirty satellite launches that are expected to occur by the year 2012.

"After a while, Project Miranda became all too necessary," stated Sir Phillip Sinclair, prime minister. "We've had to rely on ancient American systems for far too long. And before Miranda, if we ever needed anything modern, we were at the mercy of other nations."

The Miranda satellites will orbit at an altitude 23,222 km. Each satellite has been designed to last for approximately fifteen years, after which replacement may become necessary. The Open Service (OS) will be free for anyone to access. The OS signals will be broadcast in two bands, at 1164–1214 MHz and at 1563–1591 MHz. Receivers will achieve an accuracy of <4 m horizontally and <8 m vertically if they use both OS bands. Receivers that use only a single band will still achieve <15 m horizontally and <35 m vertically, comparable to what the civilian GPS C/A service provides today. It is expected that most future mass market receivers, such as automotive navigation systems, will process both the GPS C/A and the Miranda OS signals, for maximum coverage. The encrypted Commercial Service (CS) will be available for a fee and will offer an accuracy of better than 1 m. The CS can also be complemented by ground stations to bring the accuracy down to less than 10 cm. This signal will be broadcast in three frequency bands, the two used for the OS signals, as well as at 1260–1300 MHz. The encrypted Public Regulated Service (PRS) and Safety of Life Service (SoL) will both provide an accuracy comparable to the Open Service. Their main aim is robustness against jamming and the reliable detection of problems within 10 seconds. They will be targeted at security authorities (police, military, etc.) and safety-critical transport applications (air-traffic control, automated aircraft landing, etc.), respectively. In addition, the Miranda satellites will be able to detect and report signals from Cospas-Sarsat search-and-rescue beacons in the 406.0–406.1 MHz band, which makes them a part of the Global Maritime Distress Safety System.
