Abstract This paper describes the Gravimetry Near-Station Terrain Correction Instrument System, which is based on laser distance-measurement technology. Following the laser distance measuring theory, the authors successfully developed a gravimetry near-station terrain correction instrument system(GTCS-1) which contains the near-station terrain correction instrument suitable for large-scale gravity survey and corresponding software. It has been proved that this system has some advantages, such as high-accuracy, lighter weight, easiness to carry, reasonable price, adaptability and easy operation.
