The program runs under Geodetic Survey Branch (Previously known as Trigonometrical Survey Branch ) which was created in B.S. 2026 to help in establishing a network of trigonometrical points or control points for cadastral mapping works. These control points are now used, not only to tie in various maps to the national control network system, but also, to study the crustal movements of the Himalayas.

This program is involved in the measurement of geodetic data of the country and is presently involved in the preparation of a geoidal model for Nepal. Its other responsibilities include taking GPS observations, establishing higher order control points, establishing leveling network in the country, taking astronomical and gravity measurements. Various Geodetic research works have been undertaken through this program. It has established eleven absolute gravity stations in the country in a North-South sector, several GPS tracking stations. It has been taking supplementary observations at regular intervals. These tracking stations are taking continuous GPS measurements in different parts of the country for tracking the crustal movement of the Indian plate towards the Himalayas.
