2016年5月22日 · A TACAN can be installed on ships or mobile stations. The TACAN antenna is externally similar to a conventional VOR. A TACAN in Alaska during an exercise: (Source: Wikipedia) The cylinder contains the rotating antenna system. In more modern TACAN, the mechanical rotation has been replaced by electronically scanned arrays, reducing the size:

2004年3月8日 · TACAN is more accurate because, instead of having a single rotating reflector producing an AM cardioid (or is it a limacon?), TACAN has 9 extra rotating reflectors. Rather than using an omnidirectional FM signal, TACAN uses timing pulses: a 'Master Reference Burst' and others that tie in with the small reflectors.

2018年1月23日 · The TACAN station produces signals in response to the TACAN interrogation to determine range (by time measurement from the aircraft interrogation to the time of response receipt at the aircraft) and receives phase shifted signals to determine azimuth (bearing), whereas the (L-Band frequency) DME only produces range and the VOR operating at a ...

2003年3月30日 · The formula to get the DME(VOR) frequency from a TACAN channel is the following: There are two 'keynumbers' - 1063 and 1053 - which you have to add to the TACAN channel to get the DME frequency. Up to channel 59 you have to add 1063. From channes 70 on you have to add 1053. Example: TACAN channel is 44: 44 + 1063 = 1107 = 110.7MHz …

2017年12月26日 · Totally legal to tune it up & use it. If it is a VORTAC, it will work just like every other VORTAC out there. If it is a TACAN, you may be able to get DME from it, but you won”t get bearing from it without a TACAN receiver. Many, perhaps most VOR’s out there are in fact VORTAC’s — the TACAN station is colocated with the VOR.

TACAN stands for TACtical Air Navigation, a military system that is similar to VOR but with higher accuracy. It works on frequencies between 960 and 1215 MHz. Part of the TACAN is DME (Distance Measurement Equipment), which works in the same frequency band. The DME used in TACAN is the same that can be used by civil aircraft.

2020年7月24日 · DME transponders and interrogators are abbreviated TACAN transponders and interrogators. Civilian aircraft only use DME but that just means they ignore the rest of the TACAN ground station broadcast when they interrogate a TACAN ground station. A ground station will never have both DME and TACAN transponders: if it has TACAN, DME is redundant.

2020年6月4日 · A TACAN or VOR station actually transmits two signals: a reference signal whose phase shift is independent of azimuth angle; a signal that is phase shifted, where phase shift (0-360°) equals the azimth angle; At the receiver side the phase difference of both signals is determined. The phase difference equals the bearing.

2020年11月10日 · Your supposition is correct. Tuning the paired frequency will allow you to receive DME information from the TACAN. If your DME tuning is through your VOR/ILS receiver, the VOR output will be flagged no computed data (NCD) as there's no VOR signal to receive. The DME will tune the appropriate paired frequency and the DME should display normal data.

2021年11月19日 · If I understand correctly, originally DME and the equivalent distance measurement aspect of TACAN had only the "X" channels where the pulse pairs are 12 μs apart, and later the "Y" channels were introduced (to TACAN only?) with 30 μs separation. When did this happen, in the late 60s/70s era?
