Unity内のオブジェクトが変な場所に飛ぶことを解決したい

前提・実現したいこと

緯度経度を基にしてUnity内のオブジェクトを動かしたい
最初に現在地の緯度経度の場所を基準点を基に現実世界とUnity内の空間を縮尺した距離を求めオブジェクトを配置します。次に、その場所から移動先の緯度経度と基準点を基に場所を求め移動させたいです。

double型でオブジェクトの座標を取得したい
Unity内の空間は90m×90m
現実空間は30m×40m

発生している問題・エラーメッセージ

オブジェクトが平面を配置した場所以外のどこかに移動してしまう

You are trying to create a MonoBehaviour using the 'new' keyword.  This is not allowed.  MonoBehaviours can only be added using AddComponent(). Alternatively, your script can inherit from ScriptableObject or no base class at all
UnityEngine.MonoBehaviour:.ctor()
Location:.ctor(Double, Double) (at Assets/Location.cs:11)
Lookdis:Update() (at Assets/Lookdis.cs:63)
