The Russian Glonass-M navigation satellite launched into orbit in late May will go into operation on 22 June, the GLONASS information centre said Wednesday, adding that a previous device has been transferred to an orbital reserve.

"According to GLONASS System Control Centre, the Glonass-M 758 (orbital slot 12) is set to enter the orbital constellation on 22 June 2019", the centre said in a statement.

The Glonass-M 758 satellite will replace Glonass-M satellite 723, which has exceeded its expected service life by some 50 percent.
