GPS full form is Global Positioning System. GPS ek satellite-based navigation system hai jo aapki exact location (latitude, longitude, altitude) duniya mein kahin bhi batata hai — 24x7, free mein.
Quick Answer: GPS = Global Positioning System
GPS ka Full Form Kya Hai?
| Short Form | Full Form |
|---|---|
| GPS | Global Positioning System |
GPS Kya Hota Hai?
Global Positioning System (GPS) US Department of Defense ne develop kiya tha — originally military use ke liye. 1983 mein civilian use ke liye open kiya gaya. Aaj 32+ GPS satellites Earth ke orbit mein hain jo continuously signals bhejte hain.
India ka खुद का navigation system bhi hai — NavIC (Navigation with Indian Constellation) — jo ISRO operate karta hai.
GPS Kaise Kaam Karta Hai?
Satellites Signal Bhejte Hain
32+ GPS satellites continuously radio signals bhejte hain jisme unka location aur exact time included hota hai.
Aapka GPS Receiver Signals Catch Karta Hai
Aapka phone ya GPS device multiple satellites se signals receive karta hai — minimum 4 satellites se accurate location ke liye.
Trilateration Calculate Hota Hai
Device calculate karta hai ki har satellite se aapka distance kitna hai — isse aapki exact 3D position determine hoti hai.
Location Display Hoti Hai
Latitude, longitude, aur altitude calculate hokar map pe show hota hai — Google Maps ya any navigation app mein.

- Police — vehicle tracking, criminal location
GPS vs AGPS vs GLONASS
| System | Full Form | Country | Accuracy |
|---|---|---|---|
| GPS | Global Positioning System | USA | 3-5m |
| GLONASS | Global Navigation Satellite System | Russia | 5-10m |
| Galileo | — | EU | 1m (paid) |
| NavIC | Navigation with Indian Constellation | India | 5-10m |
| AGPS | Assisted GPS | — | Faster fix |
AGPS vs GPS: AGPS internet use karke satellites dhundne ka time kam karta hai — isliye phone ka GPS AGPS use karta hai jo zyaada fast hota hai.
