使用无线电计量数据进行精确的航天器导航需要了解跟踪站的位置。通过对各种空间大地测量数据的分析，许多DSN天线的位置以厘米级的精度已知。较新的DSN天线通过全球定位系统测量和常规测量相结合来确定其位置，精度为分米级。DSN天线的位置是在一个参考框架中给出的，该参考框架与例行交付给导航团队的地球定向校准一致。还描述了天线位置的不确定性。
Accurate spacecraft navigation using radio metric data requires knowledge of the locations of the tracking stations. Through analysis of a variety of space–geodetic data, the locations of many DSN antennas are known with centimeter-level accuracy. Newer DSN antennas have had their positions determined by a combination of Global Positioning System measurements and conventional survey, with decimeterlevel accuracy. The locations of the DSN antennas are given, in a reference frame consistent with the Earth orientation calibrations routinely delivered to navigation teams. The uncertainties in the antenna locations are also described.
