Administrations operating radiodetermination services ensure their effectiveness and regularity, though they accept no liability for inaccurate information or failures (28.1); doubtful observations are flagged (28.2); characteristics of stations serving maritime users are notified to the Bureau (28.3); identification avoids doubt and signals permit accurate measurement (28.4, 28.5); modifications or irregularities are notified without delay by notices to navigators (28.6 to 28.8); these rules apply to the maritime, aeronautical and general radionavigation-satellite services as stated (28.9 to 28.11); direction-finding and radiobeacon rules follow (28.12 to 28.24).
