As defined by FS-1037C and ITU Radio Regulations, radiodetermination is:
<blockquote>the determination of the position, velocity or other characteristics of an object, or the obtaining of information relating to these parameters, by means of the propagation properties of radio waves</blockquote>
There are two main fields to radiodetermination: – defined as "A radiocommunication service for the purpose of radiodetermination."
Radiodetermination-satelliteservice is – according to Article 1.41 of the ITU-RR
In order to improve harmonisation in spectrum utilisation, the majority of service-allocations stipulated in this document were incorporated in national Tables of Frequency Allocations and Utilisations which is within the responsibility of the appropriate national administration. The allocation might be primary, secondary, exclusive, and shared.
- primary allocation: is indicated by writing in capital letters
- secondary allocation: is indicated by small letters
- exclusive or shared utilization: is within the responsibility of administrations

Stations
A radiodetermination station is – according to article 1.86 of the ITU-RR – defined as "A radio station in the radiodetermination service."
A radiodetermination station uses reception of radio waves in order to determine the location of an object, under the condition that this thing is reflecting and/or transmitting radio waves. This designation may also be the collective name of any radar set in general, up to target location, illuminating, acquisition and tracking, as well as radar sigh, altimeter and precision-guided munitions or bombs.
Each radiodetermination station shall be classified by the radiocommunication service in which it operates permanently or temporarily. In accordance with ITU-RR (article 1) this type of radio station might be classified as follows:
<br />
Radiodetermination station
- Radionavigation mobile station (article 1.87) of the radionavigation service (article 1.42)
- Radionavigation land station (article 1.88) of the radionavigation service
- Radiolocation mobile station (article 1.89) of the radiolocation service (article 1.48)
- Radiolocation land station (article 1.90) of the radiolocation service
- Radio direction-finding station (article 1.91)
