Get Frequency Standards For Radar Transponders

The radar SART will not operate on other bands of radar, such as the S-band (10 cm wavelength) systems. When activated, a response from a radar SART device can be triggered by any X- band radar system operating in the vicinity of the device.

An Emergency Position Indicating Radio Beacon or EPIRB is used to alert search and rescue services in the event of an emergency.It does this by transmitting a coded message on the 406 MHz distress frequency via satellite and earth stations to the nearest rescue co-ordination centre.

A SART operates in the 9 GHz (3 cm or 'X-band') radar frequency band and, on receiving a signal from a ship or aircraft radar, transmits a series of response (homing) signals. The SART can be activated manually or automatically (in some cases) so that it will thereafter respond when interrogated.

An airplane's DME interrogator uses frequencies from 1025 to 1150 MHz DME transponders transmit on a channel in the 962 to 1150 MHz range and receive on a corresponding channel between 962 to 1213 MHz The band is divided into 126 channels for interrogation and 126 channels for reply.

the aircraft transponder transmits a coded reply on a different frequency (1090 MHz). This reply contains the aircraft identity selected by the pilot or. when the aircraft is properly equipped.

SART transponders are used to ease the search of a ship in distress or a liferaft. All GMDSS vessels up to 500 ton must carry at least one SART. Bigger vessels must carry at least two SARTs.

Transponder codes are four digit numbers with the digits limited to the range0-7. For you computer geeks, it's a 12-bit number expressed in octal notation…

In the United States, ADS-B-equipped aircraft and vehicles exchange information on one of two frequencies: 978 MHz or 1090 MHz. Mode A/C and S transponders, as well as Traffic Collision and Avoidance Systems (TCAS), use 1090 MHz.

Radars for air surveillance and air defense, for example, operate in the VHF band (30 to 300 MHz). Modern air surveillance radars with a long detection range even operate in the frequency range of up to two gigahertz (GHz). The C-band (4 to 8 GHz) is used for weather radar and monitoring the sea surface.

A SART has a receiver that detects the signals from X-band radars (9.2 - 9.5 GHz). If the SART detects a signal it immediately transmits twelve pulses on the same frequency. This signal is seen by the radar as "echoes" and will be displayed on the screen as a serie of twelve dots with a gap of 0.6 miles between them.

Transponder equivalent So, for example, the ARSAT-1 has 24 IEEE Ku band transponders: 12 with a bandwidth of 36 MHz, 8 with 54 MHz, and 4 with 72 MHz, which totals to 1152 MHz, or 32 TPE (i.e., 1152 MHz divided by 36 MHz).
