With the recent PSLV-C37 launch Antrix, the commercial wing of Indian Space Research Organization has move a step forward in gaining global recognition as one of the best in the business. Since the inception of the satellite launching the focus of service providers were on building larger sized rockets with increasing launching capabilities. On the other hand Anrix under ISRO is working on Unified Launch Vehicle or ULV that can eventually replace the GSLV or Geosynchronous Launch Vehicle in the domain of satellite launching.
ULV can Replace both GSLV and PSLV
Unified Launch Vehicle or ULV developed by Antrix would not only replace the Geosynchronous Satellite Launch Vehicle but the PSLV launch services as well. This means it will replace the Polar Satellite Launch Vehicle as well bringing in uniformity in the domain of Satellite launch services across the globe. ULV designed by the Indian satellite launch service provider can launch around 15 thousand kilograms on low earth orbit or LEO. Though there are others like the spaceX owned Elon Musk that is developing Falcon Heavy and Blue Origin owned by Jeff Bezos is developing new Glenn rocket with 50 thousand kilogram orbit lifting capacity but both are in experimental stages and may encounter unforeseen problems. On the other hand the testing of ULV developed by Antrix has been successfully completed.
Why Commercial World Goes for Small Satellite
In space launching systems most commercial buyers opt for smaller and lighter saellites. Satellites developed by SpaceX and their launch vehicles may be designed for putting into orbit substantially heavy loads. This means the launching services is meant to put into orbit heavy satellites that can go up to five hundred thousand kilograms. But the requirements in respect of the commercial satellites launch required by the commercial enterprises are otherwise. They prefer smaller and lighter satellites that cost them less but perform equally well as their heavier counterparts.
Proliferation of Lighter Satellites
During the current decade and a couple of years prior to that the world has witnessed a proliferation of smaller satellites in the orbit around the earth. There are nano, micro, as well as pico satellites. They are not only less expensive but are also easier configuring as well. Private commercial enterprises and educational institutions are significant users of such satellites. This has brought in a complete transformation in the realm of commercial satellites launch. Moreover the designers and scientists are coming up with new and innovative technologies consistently and this has also brought up a change in the approaches of the satellites launch services. In such changed scenario the ULV approach adopted by Antrix is fast catching the imagination of buyers and in consequence the Indian satellite launching service has been gaining worldwide recognition.
PSLB-C37 launched by ISRO has as many as 88 nano satellites and it forms a constellation in orbit for observing earth on a daily basis. With such new and innovative inventions Antrix is walking from strength to strength becoming a lead figure in the rank of global satellites launch services and especially in respect of the commercial satellites launch in the world of space technologies.
