<p align="justify">Tilt Compensator in Real-Time Kinematic positioning method already developed using Micro Electromechanical System (MEMS) Inertial Measurement Unit (IMU) that detect movement and tilt from lever-arm. Tilted-RTK gives advantages that receiver doesn’t need to be hold vertically, so receiver could avoid obstruction such as canopy or tree and reach more satellite signal. The ability to detect the tilt and movement is the main objective of this research, which will subtract the reference coordinates and tilted-RTK. The methodology of this research is calculating the difference between tilted-RTK coordinates and reference coordinates and calculating the RMSE after it. Primer data will be used in this research that taken in Insitut Teknologi Bandung in three different places, the first place is open-wide area and near the walls area which is Gedung Pusat Pengembangan Teknologi Industri (PPTI) and land measurement area in Lapangan Sipil area. For each area, the combination of satellites constellation are GNSS, GPS+BeiDou, and GPS only. The tilt arrangements are 15°, 30°, 45°, 55°, dan 60°. After that the difference will be analyzed by the value of RMSE that grouped by the area, tilt, and constellation. The results is good accuracy that gained from tilted-RTK, which horizontal accuracy range at 1-12-centimeter and vertical accuracy range at 1-14-centimeter, and the slight tilt and combination of satellite constellation will give the better coordinates.
