GI3002 GPS Surveying Syllabus:
GI3002 GPS Surveying Syllabus – Anna University Regulation 2021
COURSE OBJECTIVES:
To understand the working principles of satellite geodesy and its applications to solve the surveying problems.
UNIT I INTRODUCTION TO GPS
Overview-segments-satellite generations-current GPS satellite constellation-control sites positioning service-signal structure-receivers-modernization-time systems-Pseudo range and carrier phase measurements-cycle slips-linear combinations
UNIT II GPS POSITIONING MODELS AND ERRORS
Point and relative positioning-static surveying- stop and go surveying-RTK GPS-real time differentialreal time versus post processing-communication links-GPS ephemeris errors-selective availability, multipath, Antenna-phase-center variation, receiver measurement noise, satellite and receiver clock errors, ionospheric and tropospheric delay, satellite geometry measures, GPS mission planning, user equivalent range error
UNIT III GPS DATA AND CORRECTION SERVICES
Datum-geodetic co-ordinate system-datum transformations-map projections-marine nautical chartslocal arbitrary mapping systems-height systems-antenna swap method-on the fly ambiguity resolution-data service-DGPS radio beacon systems-wide area DGPS systems-multisite RTK system
UNIT IV GPS FORMATS AND INTEGRATION
RINEX and NGS-SP3 format-RTCM SC104 standards for DGPS services-NMEA 0183-IntegrationGPS/GIS, GPS/LRF, GPS/dead reckoning-GPS/INS, GPS / pseudolite, GPS/cellular-GLONASS satellite system-Chinese regional satellite navigation-regional augmentations-future European global satellite navigation system
UNIT V APPLICATIONS
Utilities and industry-forestry and natural resources-precision farming-land seismic surveying marine-airborne mapping-seafloor mapping-vehicle navigation-transit systems-cadastral surveying navigation
