I think 'Sonda Roketi' might just be intended as 'sounding rocket'.

You are correct. "Sonda roketi" is the Turkish translation of the sounding rocket.

Turkish Space Ageny released their maiden flight prediction for the indigenous SLV.

Şimşek (Lightning) 1: 550 km circular orbit (42.5-45 degree inc) - launch prediction:2027

Şimşek 2 : 700 km SSO - launch prediction: 2029-30

Şimşek 3: MEO-GEO - launch prediction: 2036

Where is Turkey going to launch from and in what direction? The country's location is not exactly favourable.

They're saying that they'll launch their SLVs from a new space center that is being built in İğneada. Not sure if they're clear with used up stages falling on Eastern Turkey/Levant for low inclination missions or on Egypt on SSO, but we'll see.

Seems like Turkish SLV development is divided up to 4 stages.

First is development of underlying technologies with sounding rockets. This was up to the most recent SR-0.1 model.

Up next is what I think is a proof-of-concept stage with SR-1.0 sounding rocket. SR-1.0 could be a direct implementation of designs they will use for their MUFS(seems like its an acronym for Micro Satellite Launch System in Turkish) SLV. According to what Roketsan wrote in their homepage :

Quote
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.

So when they are done with SR-1.0, MUFS is next to follow. It will probably leverage most of the SR-1.0 and scale it up for the 1st stage and 2nd stage. According to information I've found, third stage seems to be liquid fueled. I think it is a pressure fed engine up there. SR-1.0 will be launched on autumn this year according to Turkish sources.

Then there's another rocket called Şimşek, a liquid-fueled rocket series. I'm not sure if it is a incremental program that follows after MUFS or concurent. I personally think that they are concurrent programs, considering that the scheduled launch dates are only a year apart and they use different fuels.

Whatever it really is, I'd say it's a pretty darn ambitious plan, to put it lightly. I've thought that these kind of schedules are trademark for your average new space start-ups whose launch schedules postponed every year. Of course Roketsan, which seems to build missiles for the Turkish army including ballistic missile, would be better off than most of those start-ups in terms of meeting their goal, though I'm still dubious about their plan to launch Şimşek by 2027.

From the looks of it, both the first and second stage are powered by turbopump fed engines, most probably a GG cycle. If they were to develop an engine for a future SLV that will fly by 2027, there should have been a lot of progress regarding the turbopump development by now. I can't find any of it. In case they are getting them Yuzhmash, which seems very possible, it's still weird there ain't any information regarding the engine prototypes.

Anyways, their plan regarding liquid fuel rocket development and the lack of information regarding the engine is surely very weird. I'll stay dubious about the Şimşek until they show at least something about their engine, but MUFS seems plausible enough, albeit with very real possibilities of delays.

... MUFS (seems like its an acronym for Micro Satellite Launch System in Turkish) SLV.

indeed:

Thanks for clearing this SR-MUFS-MSLS-Simsek confusion.

Turkey tested a new sounding rocket SR-1.0 made by Roketsan.

In this test, target altitude is 300 km with 100 kg payload.

Does this mean that the apogee of this launch was 300 km?

According to the officials that was the apogee of the suborbital flight.

Does this mean that the apogee of this launch was 300 km?
