TEHRAN,Iran -- Iran's state TV is reporting the country's navy relaunched one of its Russian-made submarines after repairing its systems with locally-made replacement parts.
Iran has tried to build a self-sufficient military program since 1992.
The Tuesday report says that navy personnel overhauled the Taregh, one of its three Kilo class submarines, replacing 18,000 components including radar-evading cover, engine parts, propellers and radars.
State TV showed video of the relaunch from a dry dock in an Iranian port .
Iran added the three Kilo class submarines to its underwater fleet in early 1990s soon after it founded its submarine unit. Several smaller Iranian-built submarines have also been deployed by its navy.

Jeste to su njihovi nazivi projekta i obe varijante su označene tako i bespilotna koja podrazumjeva i borbenu bespilotnu verziju a i projekt stelth borbenog aviona je naziva SOFRE MAHI,vjerovatno je to naziv projekta koji če poslje nazvati drugačije za svaku varijantu.

Ovo je izgled buduceg aviona, a ona letelica na klipu je koliko mi se cini meta za PVO.

Na klipu je letjelica koja je ista kao i prva letjelica na prvoj fotki samo s jednim vrtikalcom i ona je bila na paradi zajdno s ove dvje ali nemam te fotke,radi se o tome da su oni radili prvo prototip za te letjelice u umanjenom modelu od 1:7 i to vjerovatno koriste kao metu za PVO i ona letjelica koja je oborena u klipu je UAV naziva ADABIL,inače prvi UAV koji su napravili za vrjeme rata s Irakom .

Iranci su najavili su da će ove godine lansirati 4 satelita.Znam malo o tome, ali me je zanimalo na koji način ih šalju na tačno određenu visinu i putanju, jer sumnjam da im dozvoljavaju upotrebu GPS u tu svrhu. Ovo su predstavili danas: "Star - finder system Nasir - 1" Evo linka i opisa funkcioniranje te naprave. Kombinacija inercijalnog navođenja i pozicioniranja na osnovu položaja zvijezda????? Postoji li u svijetu nešto slično i da li je već korišteno? Koliko je ovo upotrebljivo na duže staze?

Nasir-1 is used to accurately determine position of moving satellites in orbits and position of stars. It can record video of satellites in desired points.
This system composed of various subsystems such as Image Processor, Pattern Recognition, Optic, Electronic, Computer and Navigation, By integrating all of these systems its is possible to find exact position of satellites, aircrafts and spacecrafts.
Generally in simple satellites, INS system is used, But INS systems produce errors over the time, So for reduction of this error to determine position and guide and control satellites with more accuracy, another navigation system should be used in parallel to INS system.
INS systems uses gyroscopic sensors for positioning satellites. Position of stars can be used to reduce errors of INS system.
Human uses position of stars for navigation. This method can be used by computers in spacecrafts. Images produced by Star positioning system is analysed by image processor, stars in images are find by image processor and then position of satellites are determined by using position of stars.
In GPS systems locations are determined but in star positioning systems angles of satellites are determined.
