26 January 2023. The Galileo navigation satellite system now has a new high-precision service, the High Accuracy Service (HAS). It is freely available worldwide to anyone with a suitably equipped receiver. Delivering horizontal accuracy down to 20 cm and vertical accuracy of 40 cm, the High Accuracy Service is enabled through an additional level of real-time positioning corrections, delivered through a new data stream within the existing Galileo signal. OHB System AG, a subsidiary of the space group OHB, is the industrial prime contractor for the Galileo FOC satellites.
