| Abstract: | The algorithm of integrity with different frequencies of the EGNOS system is deduced.The regional integrity of EGNOS system is simulated under GPS and GPS/Galileo systems with different frequencies.The results show that the EGNOS can provide Cat-Ⅰ integrity requirement in case of GPS/GALILEO systems with double-frequency. |
