An unmanned aerial vehicle (UAV), commonly known as a drone, as an unmanned aircraft system (UAS), or by several other names, is an aircraft without a human pilot aboard. The flight of UAVs may operate with various degrees of autonomy; either under remote control by a human operator, or fly autonomously based on pre-programmed flight plans.

Prashant Surveys have procured a DGCA type approved Survey Grade PPK UAV / Drone ‘Lookout VTOL’ from TAS, Bangalore, in 2018, with onboard PPK NovAtel GNSS for data capture and ‘Pix4D Professional Mapper’ software to produce accuracy upto 10 cm in X, Y, Z coordinates. This technology can be used to supplement the Mobile LiDAR data output in case of urban mapping projects, or highways projects having proposed bypass roads. This is also ideal for carrying out Topographic Survey of any land where speed and accuracy is of priority, with the rates comparable to primitive Electronic Total Station (ETS) method of survey.
