HASPPP: an open-source Galileo HAS embeddable RTKLIB decoding package

Galileo supports global precise point positioning (PPP) service by delivering precise products via satellites, which is known as high accuracy service (HAS). To improve reception efficiency, the Galileo HAS employs a high-parity vertical reed-solomon encoding scheme, increasing the complexity of HAS corrections recovery. To promote research and application of the HAS, an open-source C/C + + decoding package, HASPPP, has been developed for seamless embedding into the prevalent C/C++-based software, such as RTKLIB. HASPPP provides interfaces for effortless decoding support of raw HAS binary data from various manufacturers. The HASPPP manual offers code analysis along with simple to complex examples to aid users in swiftly mastering decoding. HASPPP has undergone rigorous validation of its decoding accuracy and reliability.
