Other countries like India, China, USA, USSR did not take this path. They first perfected SLVs and then improved upon them to develop missiles.

SLVs don't need high accuracy and hence are the first step. A satellite launched to 500km orbit & one launched to 550km orbit will both work reasonably well. Then the SLVs are further improved to develop missiles by making them more accurate. So, by developing SLVs first, countries get the technology to deploy satellites along with the technology to launch missiles later on. Iran by directly going for missiles is missing out on the satellite launch capability. Also, it will be easier to benchmark the development by keeping progressively higher accuracy targets

Other countries are not Iran. Especially India which is punching way way below its weight with a billion hungry people. Iran is special, active, successful and with far outsized effect.

Comparison with ‘other countries’ is the very example of self-doubt and weakness.

can you then explain to me what was Juno I or Juno II which was based in PGM-19 Jupiter ?
what was sputnik rocket that was derived from R-7 Semyorka ?
can you explain why Long March 1 was based on DF-4?
or why Shavit-2 was based on Jericho ?


can you guys explain why Iran must answer for the route it choose in SLV development . the exat route everybody else took

gps i don't knew for it you must use higher altitude

Maybe I’m wrong. Maybe it refers to Iranian Starlink.

Salariyeh went on to say that the contract for the Martyr Soleimani satellite project has been negotiated and concluded, emphasizing that a contract for the design, construction, delivery, test, and launch of the telecommunication project has been finalized between the ISA and a domestic consortium.

The senior Iranian space official further said that the satellite system project is gradually being built, and will be put into orbit within the next two years as several domestically-developed satellites are already in line to be blasted off into space.

“Martyr Soleimani satellite constellation will initially provide narrowband IoT services, meaning it will mostly collect data from sensors on the ground and transmit it to a reference station. God willing, the number and capabilities of involved satellites will grow later on,” Salariyeh said.

sounds like a waste of time to me

Other views of the launch. Humorously the rocket fired at 5 on countdown….lol

Strong countries don't need to punch at all. Do you see China making unnecessary statements, screeching around like children.

do you want me post a certain section of the movie "Dictator" by sasha Baron Kohen
for gods sake what the being pointy or not pointy have to do with missile

I have seen that movie. But the reality is that pointy head means that it is meant to boost speed at the expense of payload. Satellites need large volume and pointy heads reduce that volume. This is why most of SLVs have mushroom heads.

SLVs generally involves using boosters to achieve high thrust in the initial stage. Iran has never even tried to use boosters but merely keep launching SLVs. It is understandable is they were merely sounding rockets being tested but that is not the case as Iran is even claiming to launch 100-200kg satellites in unstable orbits!

Making SLVs is critical in developing ICBM as the first step is always to test the basics or achieving decent accuracy & guidance control. Since SLVs need low accuracy due to high tolerance in orbital variaton, it is a good way of testing the guidance technology through progressively trying to achieve the targeted orbit.

The early ICBMs were made using derivatives of the thick SLVs with boosters. Iran's case is very different.

The recent sat launch was too important because I guess for the first time, the satellite moved independently between orbits. Now it's time for IRGC to increase the payload by enlarging their SLVs. They proved to be capable of using thrusters to move in inter orbital atmosphere.

When completed with an enlarged fully solid fuel SLV, we can have our own navigation sat at 20,000 to 30,000 KM orbits.

God speed IRGC.

I’m pretty sure this is not the first Iranian satellite to use gas thrusters to be able to move.

I read before of an Iranian satellite that has cold gas thrusters that allow it to make maneuvers. Although I guess the probability of a cube Sat being struck by debris is low. Nonetheless capability needs to be there as trash the size of a penny could completely destroy the satellite.

The question is how stable is the orbit and how complex are the instruments. Iran does not have semiconductor industry because of which it does not have the high performance guidance system. It can use 1960s technology to launch SLVs to orbits but for some reason Iran is unable to do even that.

Without achieving stable orbits which last for several years, it is meaningless to think ahead. Iran has been trying for over 15 years to launch a satellite and not even a single stable orbit has been achieved. This is despite Iran having received assistance for missile guidance from Russia/China and having developed many ballistic missiles. This is a really poor show

Says an Indian whose space program is a complete derivative of Russian technology.

Iran unlike Indians builds everything related to space tech from scratch.

And unlike the bullshit you spewed above, SLVs need higher accuracy compared to ballistic missiles.

I believe , they actually want to build something for remote control other devices .

you and your obsession with semiconductor industry .
nobody ever complained about iran missile precision in the last 15 years

and since when fibre optic gyroscope and semiconductors are 60s system
and for the record iran may have not industry level semiconductor industries but it has lab level ones . also many of these ICs can be bought from open markets

show your lack of information two of the 3 noor sats are in orbit and Noor-1 which is decayed remained there for 2 years while expected to just remain there for 1 year.
it had an altitude of 425km

do you think Soleimani name is more appropriate for a constellation of

1) spy imaging satellites
2) Iranian GPS to guide missiles
3) remote control

Indian PSLV is not derived from Russia. It was developed & perfected indigenously over 3 decades by studying missiles, sounding rockets and other basic technologies. The cryogenic engines did receive Russian help in the form of engine sales which India studied & then modified to suit itself. But even without the help, India would have developed a more expensive version of heavy lift PSLV.

As for accuracy, if you miss a 5000km ICBM missile by 10km, it will likely fall in some forest or some farmland instead of a city which will be a complete waste of missile. But if you place a satellite in 550km orbit instead of 500km, it will still work fine.

Fiber-optic gyroscopes are low accuracy systems and are excessively bulky. The latest technology is MEMS based INS systems and guidance on a chipset. These chipsets can't be bough off the shelf as they are military grade and have much higher accuracy, reliability and tolerance.

Iranian missiles use GPS guidance and are endo-atmospheric which means if countries jam GPS Iranian missiles will fail. Also, the endo-atmospheric missiles are easily intercepted.

They did not stay in a stable orbit for even 2 months. The orbits kept on decaying continuously and fell off after 2 years. Stable orbits stay the same for a decade
