I think 'Sonda Roketi' might just be intended as 'sounding rocket'.
Where is Turkey going to launch from and in what direction? The country's location is not exactly favourable.
Once the MSLV project currently underway at the Satellite Launch Space Systems and Advanced Technologies Research Center of Roketsan is complete, scheduled for 2026, it will be possible to place microsatellites weighing 100 kilograms and below in a Low Earth Orbit at an altitude of at least 400 kilometres. Turkey will thus gain possession of launch, testing and manufacturing capabilities, and the ability to establish a spaceport, placing it among only a few countries in the world with the necessary knowledge and infrastructure.
... MUFS (seems like its an acronym for Micro Satellite Launch System in Turkish) SLV.
Turkey tested a new sounding rocket SR-1.0 made by Roketsan. In this test, target altitude is 300 km with 100 kg payload.https://twitter.com/tuajans/status/1690413132550672384?s=20
Does this mean that the apogee of this launch was 300 km?
