Abstract: Изобретения относятся к наземной навигационной технике и могут быть использованы для определения высоты в произвольной точке маршрута движения относительно начальной точки движения на борту автомобиля или другого наземного подвижного объекта при проведении геодезической, топографической и других видов съемки как во время движения, так и во время стоянки. Способ заключается в последовательном измерении на исходном и каждом промежуточном пунктах маршрута атмосферного давления и температуры воздуха, обработке результатов измерений с определением высоты в каждом промежуточном пункте маршрута. Перед началом движения наземного подвижного объекта во время стоянки на начальной точке маршрута в течение некоторого времени производят измерение атмосферного давления посредством датчика давления. Записывают полученные значения величины атмосферного давления в запоминающее устройство. При этом отрезок времени, в течение которого производят запись значений атмосферного давления, измеряют посредством таймера. С момента начала движения запись в запоминающее устройство прекращают. По записанным в запоминающее устройство значениям атмосферного давления вычисляют среднюю скорость изменения атмосферного давления, поправку к измеренному атмосферному давлению и высоту в каждой точке маршрута по соответствующим формулам. Определение поправки к измеренному значению атмосферного давления и высоты в каждой точке маршрута производят с помощью вычислителя непосредственно на борту наземного подвижного объекта в реальном масштабе времени и во время движения наземного подвижного объекта и во время стоянки. Устройство для измерения высоты содержит датчик атмосферного давления, датчик температуры воздуха, вычислитель, запоминающее устройство, датчик движения и таймер, которые соединены между собой соответствующим образом. Технический результат состоит в повышении точности определения высоты, снижении стоимости оборудования, получении информации о текущем значении высоты в реальном масштабе времени непосредственно на борту наземного подвижного объекта в процессе движения и на стоянке. 2 с.п. ф-лы, 1 ил.
