Radiodetermination

As defined by FS-1037C and ITU Radio Regulations, radiodetermination[1] is:

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

RAAF AN-FPS-117 radar in 2007

There are two main fields to radiodetermination:[1]

  • radionavigation: "used for the purposes of navigation, including obstruction warning", which is mainly active;
  • radiolocation: "used for purposes other than those of radionavigation", which is mainly passive.

Radiodetermination service is – according to Article 1.40 of the International Telecommunication Union's (ITU) Radio Regulations (RR)[2] – defined as "A radiocommunication service for the purpose of radiodetermination."

Classification

This radiocommunication service is classified in accordance with ITU Radio Regulations (article 1) as follows:
Radiodetermination service (article 1.40)

Stations

A radiodetermination station is – according to article 1.86 of the International Telecommunication Union´s (ITU) ITU Radio Regulations (RR)[3] – 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 Radio Regulations (article 1) this type of radio station might be classified as follows:
Radiodetermination station
