Имеются ли статистические данные о времени, затраченном различными космическими аппаратами на связь с сетью дальнего космоса NASA (DSN)?
Было бы интересно сравнить, какие космические миссии более требовательны к времени нисходящей линии связи. Кроме того, стоимость связи DSN примерно пропорциональна затраченному времени .
Где эту информацию можно найти?
Хотелось бы увидеть ответ в виде:
"spacecraft 1 - X1 hours in year 2017"
"spacecraft 2 - X2 hours in year 2017"
или/и
"spacecraft 1 - Y1 hours during all the mission's lifetime"
"spacecraft 2 - Y2 hours during all the mission's lifetime"
РЕДАКТИРОВАТЬ:
Возможно , этот ответ касается проблемы, но я не уверен.
Я отправил запрос FOIA для каждого контакта, установленного DSN с 2010 г. (я получил контакты с 1 января 2010 г. по 1 сентября 2018 г.)
Вот краткое изложение времени контактов для всех 86 миссий, с которыми DSS связался за это время, отсортированное по общему времени (в часах).
