Abstract

Изобретение относится к способу (50) оценки разности длин путей передаваемого космическим аппаратом или самолетом (20) сигнала, приходящего соответственно на первую приемную антенну (32а) и вторую приемную антенну (32b) приемной базы. Способ (50) содержит этап (500), на котором измеряют полезную разность фаз между сигналами, соответствующими целевому сигналу, принятому соответственно первой приемной антенной (32а) и второй приемной антенной (32b); и этап (502), на котором оценивают разность длин путей на основе измерений полезной разности фаз. Упомянутый способ (50) дополнительно содержит этап (504), на котором передают калибровочный сигнал на приемную базу; этап (506), на котором измеряют калибровочную разность фаз между сигналами, соответствующими калибровочному сигналу, принятому первой приемной антенной (32а) и второй приемной антенной (32b); и этап (508), на котором компенсируют вариации измерений калибровочной разности фаз относительно измерений полезной разности фаз. Изобретение также относится к системе (30) оценки разности длин путей.
