The paper provides an assessment of compatibility among NavIC, GPS and Galileo systems. Simulations are performed taking into account the intersystem interference between NavIC and GPS system in L5 band and NavIC and Galileo in L5 and E5a band on Indian region. Parameters considered in simulation are Space Constellation, ground cycle repeat time of satellite, EIRP etc. It is shown that the intersystem interference of Galileo caused by NavIC is slightly larger than interference of IRNSS due to Galileo. Similarly, the intersystem interference of GPS caused by NavIC is slightly larger than interference of NavIC due to GPS. Maximum interference is considered for all the cases.
