Abstract
【解決手段】クライアント/サーバアーキテクチャにおいて衛星位置決めシステム(SPS)受信機を操作するための装置および方法。方法の1事例において、第1の時間に第1の複数の擬似距離が決定され、第1の時間の後の第2の時間に第2の複数の擬似距離が決定される。第1の複数の擬似距離および第2の複数の擬似距離は記憶される。第2の時間の後、第1の複数の擬似距離および第2の複数の擬似距離は、通常1つの送信でロケーションサーバに送信される。該ロケーションサーバはその後、該第1の複数の擬似距離から第1位置を決定し、該第2の複数の擬似距離から第2位置を決定する。1つの特定の例においては、該第1の複数の擬似距離および該第2の複数の擬似距離は、所定の種類の事象に応答して送信され、該ロケーションサーバは、時間にわたり収集されたディファレンシャルGPSデータの集合を記憶する。
