The Galileo High Accuracy Service (HAS) provides free access to an accurate positioning solution using a Precise Point Positioning algorithm in real-time. HAS boasts accuracy down to around 20 centimetres, making it ideal for applications which require a higher performance than what is offered through the generic Galileo Open Service. Applications include farm machinery positioning, offshore exploration and mapping, autonomous vehicles, drone navigation and positioning systems, maritime port operations, and more!
A special module called the High Accuracy Data Generator receives data from the Galileo Sensor Stations and generates corrections for Galileo and GPS signals. The High Accuracy (HA) corrections are relayed in real-time to the Galileo core infrastructure, which compiles the information and uploads the HA data back to the Galileo satellites. Finally, these satellites broadcast the HA data, which are picked up by all HA-enabled receivers.
User receivers integrate the HA corrections to the supported Galileo and GPS signals. Then, they compute precise positioning information through advanced algorithms.
Other Galileo services
Galileo’s Open Service (OS) is a free Positioning, Navigation, and Timing (PNT) service for global users. It is embedded in almost all smart devices such as smartphones, smartwatches, wearable health devices, in-vehicle navigation devices, and many more.
The Galileo Search and Rescue Service (SAR) swiftly relays distress signals to search and rescue crews, thereby supporting life-saving missions.
The Galileo Public Regulated Service (PRS) is a robust, encrypted navigation service for the European Union and partner countries’ government-authorised users.
