SRISAT: New Iranian Satellite

[Arminkh]

This new satellite was paraded in ELECOMP exhibition in Tehran.

SRISAT is a telecommunication and research satellite. SRISAT was designed and built last year by Iran's satellite system research center and after launch can send and receive short radio messages.

SRISAT weighs 47kg and is supposed to be launched to elliptical (250,375) orbit and will remain there for 2 months.

Its missions include:

-Test its tracking system using Iran's built GPS system.
- Test the performance luck and release system of its solar panels
- Test the performance of its power generation and transmission in real space environment.
- Test the performance of local built IMU system.
- Test new communication systems.

Specifications:

SRISAT dimensions are 480x490x610mm without the antenna and 550x780x780 with antenna. It will generate power using two dynamic 610x445mm solar panels and has three Ion-lithium 18 Amp-hour battery packs.

It uses GPS receiver and Ranging transmitter to determine its location and speed with a precision of 20m and 0.5 m/s. This is the first Iranian GPS system ever tested in space.

The other new feature is having two separate processing circuits which will back each other up in case one of them fail.

The other new feature are its folding and dynamic solar panels that will open when in orbit. They will open up 0.046 degrees every 4 millisecond and reach full 90 degree after 8 seconds.

For radio transmission it uses two bi and one directional modules. It will receive tele-commands in VHF and transmit its telemetry info in UHF.

Dimensions and materials used for its construction:

SRISAT is built out of 7000 grade aluminum. High Zn content in this alloy will give it higher strengths and resistance against heat.

Good!...any news on launch?.....I think your Safir is going to be used for its launch.....any date though?

One was planned to be launched before the anniversary of Iran revolution which is almost 1.5 month away. But not sure if it is going to be this one or another one.

Iran has 3-4 satellites in the line to be launched.

Manteghi, head of ISA said they are going to test Simorgh rocket ( with a dummy payload ) .

Waiting for five years now. Hopefully it can be more useful in practical application than Safir.

Sure , Better than Safir but still a long way to go .. I wish they would focus on solid rockets more .

Good. Making these things independently is not an easy task.

I understand the utility of solid rockets specially from the point of national defense and I believe Iran should double down on them, as they can be of dual use.

But I firmly think Iran should some time in future, separate its military program from civilian one. The goals of each are different and can not be served by a single structure. In civilian sphere for example if Iran really wants to become a serious player in earning money from space, and reap economic benefits, then the way to go is liquid rocket, specially if possible the oxygen-kerosene engines, modeled after Russia. The whole R&D approach of civilian side is different from the military side. That is why it would be important to separate these two.

I see bro . But i ( personally ) think that we don't need a full scale launch capacity . We can earn money by sending sats with cheap SLVs into LEO but a bigger program has another story . First , It's damn risky to launch a 500 million $ Geo sat with a domestic launcher , Second we can't provide GEO services cheaper than India , Russia , China. Iran is not near equator like India (means we need to make bigger rockets ).so we won't earn money . Developing a GSLV in a country with a billion population is ok but for us is wasting money . A solid rocket can be of dual use , Some level of cheap launch services , earning some money and we don't even have to waste more money for 2 parallel programs .But again, that's my personal preference .

 

[The Last of us]

Whatever happens, even when Iran gets the capability for launching much heavier satellites into space I hope development of small satellites does not stop. Micro and nano satellite technologies are something we should peruse as well and not move on simply to much larger satellite. People automatically assume a heavier satellite = better satellite. While this historically has been true, in the future, the achievement will be making small satellite which can provide the required functions. Why not have the best of both worlds and have the technology for both small and large satellites.

I see your point. But there is only one issue which is true across the board for all science and technology projects. Unless you do not aim really high enough (actually aiming to conquer the universe), then not much will happen. Space endeavors are no different. One thing leads to other.

Because it is a strong belief that propels mankind to do something great, not really money. Money is just a desirable side effect of this way of thinking.

Iran must aim for 'naming rights'. Regardless of what others do. You can't do such things with half a heart. Extreme love must be involved:

Space technology Iran is miles ahead than pakistan.
