The launch of the second GPS III satellite from Cape Canaveral, scheduled for 25 July, has been put back to 22 August at the earliest.
The United Launch Alliance (ULA) has confirmed that the delay is due to an anomaly in a component in the upper stage of the Delta 4 launch vehicle. The first Lockheed Martin GPS III satellite was successfully launched on 23 December 2018.
GPS III satellites have an extended lifespan of 15 years. The manufacturers claim 3-times better accuracy and up to 8-times improved anti-jamming capabilities compared with the newest GPS II satellites. They will also transmit the L1C civil signal, making them compatible with other GNSS such as GLONASS, BeiDou and Galileo. It is hoped that full GPS III functionality - although still employing some GPS II satellites - will be achieved by January 2023.
