## Abstract
Abstract A system that can position objects while working in the field is very important as a navigational reference for a smart tractor. In this research, a local positioning system based on rotating lasers with 4 receiver poles was developed. The method used is to rotate the laser (transmitter) with a constant speed, then calculate the trigger time on each pole (receiver), so that the angle between the laser and each pole can be determined. Then the coordinate’s position of the laser is calculated by the triangulation method, with a mean of 4 predicted positions. The static tests were carried out in a field with a length of 10,000 cm and a width of 5,000 cm under daytime and night time conditions. Measurements were carried out at 5 critical positions, namely in the middle (ps1), the lower left corner (ps2), top left corner (ps3), top right corner (ps4) and bottom left corner (ps5). The average error on position reading is not too different, that is 16.8 cm during the day and 23.2 cm at night. The smallest error is 5.7 cm in ps4 while the biggest error is 37.4 cm in ps1 all of which were tested at night.
