Our Process With Clients

GoSoft provides survey data with site coordinates on a GIS Map that helps real estate companies obtain a No Objection Certificate (NOC) from Airports Authority of India (AAI). We have years of experience and first hand knowledge of the documents and formalities necessary to obtain No Objection Certificates from AAI and the Air force for objects of vertical significance around an airport.

Methodology and Accuracy

Differential Global Positioning System (DGPS) is an enhancement to Global Positioning System that provides improved location accuracy, from the 3 to 10 meter nominal GPS accuracy to about 15 cm in case of the best implementations.

DGPS uses StarFire, which is a wide-area differential GPS developed by John Deere’s NavCom and precision farming groups. StarFire broadcasts additional “correction information” over satellite L-band frequencies around the world, allowing a StarFire-equipped receiver to produce position measurements accurate to well under one meter, with typical accuracy over a 24-hour period being under 4.5 cm. StarFire is similar to the FAA’s differential GPS Wide Area Augmentation System (WAAS), but considerably more accurate due to a number of techniques that improve its receiver-end processing.
