Pinpoint anywhere on earth for better navigation



Have you ever faced an issue telling your address to a delivery agent?
Do you still depend on landmarks for navigation ?

These three words will save you from this and it's not Oh My God 🤣🤣



Problem:

Street addresses/GPS are not accurate enough to specify precise locations, such as building entrances, and parking exits because GPS with cellular tower data will have an RMSE(Root Mean square Error) of 10 meters and this number can vary depending upon satellite positioning, hardware of GPS coordinates receiver, and rural areas, etc



Why is GPS alone not enough?

GPS (Global Positioning System) mainly depends on strong signals received from satellites positioned across the globe, every smartphone has a receiver (inbuilt) to receive these signals and also uses cellular tower signals to pinpoint your correct accurate location if the object is in motion.


Many GPS devices ideally need to receive signals from at least 7 or 8 satellites to calculate location to within about 10 meters. With fewer satellites the amount of uncertainty and inaccuracy increases. With less than 4 satellites, many GPS receivers struggle to produce accurate location estimates and will report “GPS signal lost” at points during the route. Imagine pinpointing Rural areas because there is a high chance of fewer satellites.
