It can be safely commented that positioning system technology used in PA is mature.
Development of perfectly clear 3-D picture of ground terrain with ‘synthetic vision’ by the help of
GPS will create scope of precision ploughing, irrigation etc. Farther improvement by the use of
RTK DGPS, introduction of regional satellite positioning system by Quasi-Zenith Satellite System, coupling of GPS with Inertial Navigation System (INS) will make positioning technology
more robust, accurate and cheap.
