फिक्र न कर

कहते है की असफलता ही सफलता की कुंजी है ,ये बात तो बहुत छोटी सी है लेकिन सफलता का राज इसमें छिपा है | कोई भी सब कुछ सीख कर पैदा नहीं होता ,सब यही सीखते है इसी  दुनिया में , यहाँ आदमी सिखने के लिए ही पैदा होता है | हाँ ये बात अलग है की कोई बड़ा जल्दी सीख लेता है और कोई थोड़े समय में ,और हम सिखने के क्रम में कितनी बार हारते है ,असफल होते है और अंततः सीख लेते है समझिए सफल होते है | शायद यही बात प्रतियोगिता , परीक्षा के लिए भी लागु होता है  हम हमेशा सीखते है हारकर भी , 
इसलिए   कर्म किये जा ,फल की तू फिक्र न कर ||


सिने में तूफान  छुपा है ,
आँखों में आसमान  है |
दुनिया हो मेरी  मुठी में 
ऐसे ही अरमान है ||

कस्ती लगेगी किनारे 
ऐ मन तू फिक्र न कर |
आगे देख चलता रह ,
रुकने की तू जिक्र न कर ||

जिन्दा है तू तो संघर्ष कर ,
मंजिल ही तेरा सुकून है |
तू जिन्दा है ,इस धरती पर ,
जब तक तुझमे जूनून है ||

जिद

एक सूनापन सा है आँखों में ,
दिल में एक तन्हाई सी है |
कुछ कचोटता है सिने में ,
दिल की खुद से बेवफाई सी है |


जीवन की राहें  रूकती नहीं ,
और जीनें की जज्बा है की झुकती नहीं |
लौ सुलगती  रही है उठने  को ऊपर,
पर  झुकाने को निचे ,बारिश है की रूकती नहीं ||

अब सोच की छतरियों से काम नहीं चलता ,

हिम्मत से कम लेनी पड़ेगी ||
चोट भले ही थोड़ी  खानी पड़े ,
पर  राह - ए मंजिल बनानी पड़ेगी ||

Locational Accuracy

Angels of locational accuracy

Satellite navigation system consist of satellites that provide spatial positioning and enables hand held devices to determine accurate position using time signal

Current global satellite navigation systems

    Global positioning system (GPS) :

    the most utilised system .consist of up to 32 medium orbit satellites. Operational            since 1978 and globally available since 1994

    GLONASS (Global navigation satellite system ) :

   consists of 24 satellite ,operated by Russian aerospace defence forces

   DORIS ( Doppler orbitography and radio positioning integrated by satellite )

   French precision navigation system based on static emitting station around the world.    Limited in uses and coverage. used with other global navigation satellite system           (GNSS)

Navigation system under development

          Galileo

           To be managed and operated by the European union (EU) and European space              agency (ESA)

         BeiDou

          Managed by china .currently functional in Asia pacific as a  16 satellite system

India and its satellite navigation plan

             India has a two pronged satellite navigation Sat Nav plan

           GAGAN

           GPS aided geo augmented navigation

           IRNSS

            Its full form is  Indian regional navigation satellite system

            It is a 7 satellite navigation system.   In this Indian space agency ISRO have already established 4 satellite in orbit ,and by march 2016 all satellite will be in orbit and by mid . 2016.

Volga The longest river in Europe

Volga  The longest river in Europe

Volga, river in western Russia, longest and one of the most important rivers of Europe. The Volga River rises northwest of Moscow in the Valday Hills and flows 3,700 km to the southeast before emptying into the Caspian Sea near the city of Astrakhan . It is navigable for about 3200 km  and large numbers of ships ply its waters with freight and passengers. The Volga is fed by more than 200 tributaries (about 70 of which are navigable), including the Kama, Samara, Oka, and Vetluga. Together, the Volga and its tributaries occupy a watershed covering about 1,450,000 sq. km  or about 40 percent of European Russia.

Danube River

Danube River

Danube is second longest river in Europe, it is longest river in European union region, and one of the principal transportation arteries on the continent. It is the only major European river to flow from west to east. It rises in the Black Forest region of Germany and flows in a generally easterly direction for a distance of about 2850 km, emptying, on the Romanian coast, into the Black Sea. The delta of the Danube is a region of desolate marshes and swamps, broken by tree-covered elevations. The Danube is navigable by ocean vessels to Brăila, Romania, and by river craft as far as Ulm in Germany, a distance of 2,600 km. About 60 of the approximately 300 tributaries of the Danube are navigable. The principal ones, in the order in which they merge with the Danube, include the Lech, Isar, Inn, Morava, Váh, Raab (Rába), Drava (Drau), Tisza, Sava, Siret, and Prut.

The Danube basin, more than 777,000 sq. km in area, includes parts of Germany, Austria, Slovakia, Hungary, Serbia and Montenegro, Croatia, Bosnia and Herzegovina, Slovenia, Bulgaria, Romania, and Ukraine. Important cities on the river include Ulm, Regensburg, and Passau, in Germany; Linz and Vienna, in Austria; Bratislava, Slovakia; Budapest, Hungary; Belgrade, Serbia; and Galaţi and Brăila, in Romania. Canals link the Danube to the Main, Rhine, and Odra (Oder) rivers, providing a commercial route between the Black and North seas. The Danube Valley between Linz and Vienna, Austria, is noted for its beautiful scenery.
