The temperature in the launcher building is controlled and the launcher is constructed so that the rocket is elevated and positioned in azimuth ready for launch, with the building closed. Just before launch, the roof and blast doors are opened. In the event of a hold after the opening of the building it can be closed and the temperature rapidly brought back to that desired, to protect the motor and payload. The launcher elevation and azimuth and the building roof and blast doors can be controlled locally or remotely from the blockhouse. Azimuth and elevation angles, roof and blast door positions and tower temperature are monitored on the launch console.
Power outlets are available at the payload platform.
The MRL 7.5K launcher is a 11.3 m long single rail underslung beam launcher stored in a protective house with removable roof. For each countdown the roof is removed and the beam is elevated and turned to its launch position. During stand-by for launch, the vehicle is protected by means of a styrofoam tunnel and heated by oil burners. The launcher is remotely controlled and monitored from the launch console in the blockhouse. The launcher itself is a very simple stool support with retractable locking devices that secure the motor in windy conditions.
