Explanation:

IRNSS has three satellites in geostationary and four satellites in geosynchronous orbits: This statement is correct. The IRNSS consists of three satellites in geostationary orbit and four satellites in geosynchronous orbit that have an inclination to the equatorial plane. This configuration is designed to provide accurate position information services to users in India as well as the region extending up to 1500 km from its boundary.

IRNSS covers the entire India and about 5500 sq. km beyond its borders: This statement is inaccurate in terms of the area mentioned. IRNSS is designed to provide accurate position information services to users in India and the region extending around India up to approximately 1500 km from its boundary, which is significantly less than 5500 square kilometers.

India will have its own satellite navigation system with full global coverage by the middle of 2019: This statement is incorrect., the IRNSS, also known as NavIC (Navigation with Indian Constellation), is primarily a regional navigation system, not a global one. It was designed to provide accurate position information services in India and its vicinity, rather than global coverage.

Therefore, out of the statements given, only statement 1 is correct.
