- 25. CONCLUSION • Through this project we got the knowledge about the hydropower survey ,providing the feasible site location of hydropower component • The head difference was of 24.89m which produced the energy of 529.304KW. 23 December 2015 25
- 27. INTRODUCTION • Satellite-based radio-navigation system that is capable of providing extremely accurate worldwide, 24-hour, 3- dimensional location data • The system was designed and is maintained by the US Department of Defense (DoD) as an accurate, all-weather navigation system, in 1970s • Though designed as a military system, it is available with certain restrictions to civilians 27 GP S sur vey 23 December 2015
- 28. The Working Principle of GPS • Position of a unknown object can be identified by measuring range/distance of the object from at least three known position, a well-known principle of trilateration in traditional surveying • The distance from satellite to earth is calculated by using the relationship of velocity of light signal and time taken to reach the earth • In GPS, at least three (actually, 4) known positions of satellite are used to identify the unknown position on (or above) the earth surface 28 GP S sur vey 23 December 2015
- 29. Components: Space Segment • Consist of 24 operational and 5 backup satellites • 6 orbital planes at inclination 55° and 60° apart • Satellite altitude about 20,200 km • Orbital period 12 hrs • Each GPS satellite transmits a signal, which has a number of components: two sine waves (also known as carrier frequencies): L1(1575.42 MHz) and L2 (1227.60 MHz) two digital codes and a navigation message: • Main functions of Space segment Receive and store data from control segment Maintain a very precise time Transmits coded signals to user receivers through two carrier frequencies 29 GP S sur vey 23 December 2015
- 30. Components: Control Segment Consists of Master control station (1 functional+ 1 backup) at Colarado Springs, three uploading stations, six monitor stations and ten national geodetic stations Functions Monitor the satellites Estimate the on-board clock state and define the corresponding parameters to be broadcast Define the orbits of each satellites in order to predict the ephemeris and almanac Determine the altitude and locations of satellites in order to determine the parameters to be sent to the satellites for correcting their orbits 30 GP S sur vey 23 December 2015
- 31. Components: User Segment • The user segment includes all military and civilian users • With a GPS receiver connected to a GPS antenna, a user can receive the GPS signals, which can be used to determine his or her position anywhere in the world • GPS is currently available to all users worldwide at no direct charge 31 GP S sur vey 23 December 2015
- 32. Limitations of GPS Surveying Atmospheric Errors: Ionosphere and troposphere delays Signal multipath errors Satellite clock errors Receiver clock errors Orbital/ephemeris errors Number of satellite visible Dilution of precision(DoP): VDoP, HDoP, GDoP, and PDOP Selective availability and anti-spoofing 23 December 2015 32 GP S sur vey
- 33. Positioning Methods • Commonly two type of positioning methods Absolute or point positioning : uses the single receiver, most basic and common, less accurate and fast technique, also called standalone/absolute/autonomous positioning Differential or relative positioning: uses at least two receivers (base/stationary/reference receiver and rover/ roving receiver), attain higher accuracy than point positioning, 33 GP S sur vey 23 December 2015
- 34. OBJECTIVES • The main objectives of this project is to prepare the map showing all the government offices in Pokhara municipality. • The other objectives are as follows; To know about handling handheld GPS device To use GPS as the technique of data collection for GIS 34 GP S sur vey 23 December 2015
- 35. STUDY AREA 35 GP S sur vey 23 December 2015 Geographic location: 28-50-50 N, 83-58-20 E Area: 55.222 square KM Highest elevation: 1740 m Lowest elevation :827 m
- 36. METHODOLOGY 36 Data Collection Data Transfer Map Preparation GP S sur vey 23 December 2015
- 38. CONCLUSION AND RECOMMENDATION 38 GP S sur vey 23 December 2015 GPS survey is most useful and for regional scale it is best suited for thematic mapping in the present context of surveying In this camp, all government offices are not known to us and hence all offices are not mapped in this map
