Isro has rescheduled the high-profile launch of its advanced communication satellite GSAT-11, the heaviest made in India, from Kourou, French Guiana, for additional technical checks.

The decision comes weeks after its communication satellite with military applications GSAT-6A went missing after a perfect launch.

GSAT-11, with a lift-off mass over 5,700 kg, was initially planned to ride piggyback with co-passengers on Ariane space rocket on its mission on May 25.

"The launch of GSAT-11 scheduled during May 2018 from Kourou, French Guiana is rescheduled. The revised launch date will be communicated subsequently," the Bengaluru-headquartered Isro said in a brief statement.

The space agency gave no reason for rescheduling the launch.

However, in a statement on its website, European space transporter Arianespace said the Ariane 5 launch numbered VA243 had been postponed due to additional technical checks the satellite needs to undergo. It said the Ariane 5 launch was initially planned for May 25.

Arianespace was also scheduled to put into space Azerspace-2/Intelsat-38 along with GSAT-11, which is designed to provide 12 Gbps (gigabit per second) capacity and multi-spot beam coverage over the Indian mainland and nearby islands, bringing significant advantages to the user community.

The GSAT-11 had arrived at the European spaceport in French Guiana in South America on March 30.

In August last year, India's mission to launch its backup navigation satellite IRNSS-1H on board PSLV-C39 ended in a failure after a technical fault on the final leg following a perfect launch.
