摘要 The ITU Radiocommunication Assembly,
considering
a) that the band 406-406.1 MHz has been allocated in the Radio Regulations to the mobile-satellite (Earth-space) service for use by emergency position-indicating radio beacons (EPIRBs) in cases of distress or emergency;
b) that administrations may also authorize use of personal locator beacons, emergency locator transmitters, or equivalent systems, on a national basis using transmitter radiation parameters and characteristics similar to those of EPIRBs;
c) that as part of the Global Maritime Distress and Safety System, the International Maritime Organization has required carriage of EPIRBs aboard ships operating under the Safety of Life at Sea Convention;
d) that the purpose of EPIRBs and equivalent systems is to facilitate search and rescue operations by means of satellite locating techniques;
e) that the use of satellite EPIRBs and related satellite systems is designed to save lives by efficiently bringing rescue services quickly and directly to those in distress;
f) that satellite receivers have revealed the presence of many interference sources in the band 406-406.1 MHz in regions of the Earth;
g) that presence of any interference leads to deterioration in the search and rescue satellite system which works on the basis of statistical processing of low-power signals and that such interference may threaten the safety of life or property;
h) that severe interference in the band 406-406.1 MHz has already been shown to be able to completely mask EPIRB transmissions over ocean areas covering thousands of square kilometres;
j) that the Radiocommunication Bureau has a programme of coordinating reports of interference in the band 406-406.1 MHz on a worldwide basis and communicates those reports to appropriate administrations, requesting their assistance in eliminating such interference;
k) that national radio monitoring services may be in a good position to assist in detecting, localizing, and identifying interference sources in this band and thereby significantly contribute to protection of life and property
