前記切り替えるステップを制御する制御信号は、前記受信機が現在置かれている位置に関する時間指示信号に基づくローカル環境の推定に基づいて発生され、
成功した捕捉ストラテジーを記録し、この先の基準としてそのストラテジーを特定の環境条件に相互に関連させるステップを含み、
複数のGPS受信機の間でそのようなストラテジーを共有させるために、成功した捕捉ストラテジーを決定するステップを含み、
基地局、さらなるデバイス及び/又はブルートゥース(登録商標)ビーコンネットワークのような遠隔デバイスから前記受信機に信号捕捉プロファイルを送るステップを含み、
要求信号を捕捉するためにハードウェア相関器又はソフトウェア相関器のどちらを用いるかを決定するステップを含む、
ことを特徴とするGPS受信機の操作方法。 - 前記切り替えるステップを制御する前記制御信号は、前記受信機のユーザにより直接入力させるようにユーザインタフェースにより送られることを特徴とする請求項1に記載の方法。
- 前記切り替えるステップを制御する前記制御信号は、遠隔の信号発生手段から送信されることを特徴とする請求項1に記載の方法。
- 前記制御信号は、追加の通信デバイス、基地局又はブルートゥース(登録商標)ビーコンネットワークを有する信号送信機から受信されることを特徴とする請求項3に記載の方法。
- 積分期間にわたる受信信号の処理を通してGPS信号を捕捉するためのGPS受信機であって、
前記受信機は、少なくとも2つの別個の値の前記積分期間のいずれかで操作し、前記積分期間を前記少なくとも2つの別個の値の間で切り替える制御手段を含み、前記制御手段は、前記受信機が置かれた環境を示す信号に対応し、
前記受信機は、それぞれ異なるセットの積分期間を有する複数の異なる所定の操作プロファイルを使用し、前記少なくとも2つの別個の積分期間は、前記各プロファイルの一部を形成し、
前記制御手段を制御する制御信号は、前記受信機が現在置かれている位置に関する時間指示信号に基づくローカル環境の推定に基づいて発生され、
成功した捕捉ストラテジーを記録し、この先の基準としてそのストラテジーを特定の環境条件に相互に関連させる手段を含み、
