Abstract: Изобретение относится к электронным цепям приемников, используемых в Глобальной Системе Определения Местоположения Абонента. Достигаемым техническим результатом является уменьшение частотной погрешности гетеродина приемника путем введения компенсации в соответствии с рабочими условиями. Частотная погрешность гетеродина минимизируется с помощью характеризации гетеродина. Опорный сигнал от внешнего источника, содержащий минимальную частотную погрешность, подается на электронное устройство. Внешний сигнал используется как опорная частота для оценки частотной погрешности внутреннего источника частоты. Электронное устройство отслеживает параметры, которые влияют на точность частоты внутреннего источника. Одним из параметров, влияющих на частоту внутреннего источника, является температура. Электронное устройство собирает и запоминает величины таких параметров, а также величины соответствующей им частотной погрешности внутреннего источника частоты. Полученная характеристика внутреннего источника частоты используется для его компенсации, когда на него не поступает внешний опорный сигнал. 2 н. и 15 з.п. ф-лы, 7 ил.
