Zusammenfassung:	The invention provides a method for improving locating precision. According to the method for improving locating precision, under the condition that locating data of any two entities and the distance between an entity and the entities can be known, a binary equation set is established by utilizing locating data of the entity and the distance between the entity and the two entities, and estimated locating data of the entity can be obtained by solving the equation set; estimated locating data meeting the requirement are selected to serve as candidate locating data according to the situation that the distance between the original locating data of the entity and the estimated locating data is smaller than a first threshold; high precision locating data of the entity is selected from the candidate locating data. According to the method for improving locating precision, the entities in a small range (such as hundreds of meters) can be accurately located, locating accuracy is effectively improved, cost is very low,
