The test version of a unique satellite navigation receiver has been delivered for integration testing on SSTL's Lunar Pathfinder spacecraft. The NaviMoon satnav receiver is designed to perform the furthest ever positioning fix from Earth, employing signals that will be millions of times fainter than those used by our smartphones or cars. The 1.4 kg receiver is seen connected to the Low Noise Amplifier that pinpoints and amplifies the signals to the a useable level.
