イプシロン3号機の（仮＝借り）KMLに含まれる座標を
WolframCloudに読み込んで作図してみた。線の色は次の通り。
赤 第１段 燃焼中
緑 第１段 燃焼終了・分離
橙 第２段 燃焼中
青 第２段 燃焼終了・分離
黄 第３段 燃焼中
これを描くプログラムの処理部分はこんな感じ。たったこれだけで描ける。
右下で色が薄くなっているのは太陽があたっている部分。
NightHemisphere関数で一発描画可能。上図はリフトオフ時刻のもの。
時刻を進めるとこの境界はどんどん西に移動してくる。
背景は GeoBackground -> GeoStyling["StreetMap"] で指定する。
ReliefMapの方がきれいだけど日当たりの状況がわかりにくいので...
画像を貼ってしまったが秒は13ではなく11だったので訂正必要 ↓
自分でWolframCloud上で試したい人のためにKMLデータを代入するところも含んだ全てのソースを貼っておく。KMLには時刻情報も含めているのでアニメーションも作れるはず。少し加工すればKMLファイルに復元することも可能。
以下コピペ用ソースのすべて。貼り付けてShift+Enterで実行される。
慣れた人ならもっとエレガントに書けると思う。
というか、テレメータ等で取得した本物の軌道データ、欲しいなぁ...
森田先生お願いします。 m（..）m
