| Abstract: |
| The reentry low altitude target's positioning technique based on 3(t p assive position-finding principles is discussed in this paper. At first its basi c principle is introduced, and we discuss the sources of errors in the existing telemetering system and corresponding precision. Some methods, which are used to improve the precision, are proposed at the end of this paper. |
