GPS と BeiDou GEO の混合解析による BeiDou GEO の影響調査 BeiDou の GEO 衛星は静止衛星であり、衛星の仰角、方位角が一定である。マルチパ ス誤差は一般的に仰角により変化するが、静止衛星では変化が小さくなるため、マルチ パス誤差が大きい場合、測位に悪影響を及ぼすことが懸念される。そこで、GPS と BeiDou の GEO 衛星のみを使用し、GPS と BeiDou で位相差を取らない混合解析で基 線解析を行い、解析結果の残差の確認を行った。 0m 基線観測条件の 8 月 9 日 24... から、表 2-20 と報告と同様に、BeiDou GEO とそれ以外との衛星との間に L1 の みにおいて、0.5 サイクルに相当する約 10cm の搬送波位相の差が確認された。 42 ●フィックス解、●フロート解 擬似距離残差 搬送波位相残差 BeiDou GEO GPS, BeiDou MEO, BeiDou IGSO SNR と仰角 図 2-31 GPS と BeiDou の混合解析結果 L1 残差、SNR... モデル 対流圏補正 Saastamoinen モデル 除去衛星 BeiDou C02 解析結果を衛星系の組み合わせごとに表 2-65 から表 2-68 に示す。また、フィックス 解の割合のプロット図及び座標の精度のプロット図を図 2-54 から図 2-61 に示す。 なお、表の補正の分類は下記のとおりである。  BeiDou のみ BeiDou のみの解析  混合解析 BeiDou と他の衛星系で位相差を取らない混合解析  統合解析 全補正なし BeiDou と他の衛星系で位相差を取る統合解析 擬似距離 ISB、搬送波位相 ISB とも補正なし  統合解析 擬似距離 ISB 補正なし BeiDou と他の衛星系で位相差を取る統合解析 擬似距離 ISB 補正なし、搬送波位相 ISB 補正あり  統合解析 搬送波位相 ISB 補正なし BeiDou と他の衛星系で位相差を取る統合解析 擬似距離 ISB 補正あり、搬送波位相 ISB 補正なし  統合解析 全補正あり BeiDou と他の衛星系で位相差を取る統合解析 擬似距離 ISB、搬送波位相 ISB とも補正あり BeiDou のみの解析では、フィックス率が 100%、 、BeiDou と他の衛星系の組み合わせ による混合解析でも 100%のフィックス率であった。座標の精度については BeiDou の みと比較し混合解析の方が向上した。 BeiDou と他の衛星系の組み合わせによる統合解析では、BeiDou と Galileo の組み合 わせ以外、擬似距離 ISB 補正と搬送波位相 ISB 補正の両方を補正することで 99.9%以上 のフィックス解が得られた。BeiDou... の補正値が小さいためと推測される。しかし、擬 似距離 ISB のみの補正では座標の精度が補正ありに比較し低下した。 BeiDou と GPS、GLONASS、Galileo の組み合わせでは、BeiDou のみと比較し、統 合解析においても座標の精度向上がみられた。 BeiDou と QZSS の組み合わせでは QZSS が 1 機のため座標の精度向上はわずかであった。 BeiDou と他の衛星系の組み合わせによる統合解析において、擬似距離 ISB、搬送波 位相 ISB を補正することでフィックス解が得られることが確認できた。また、BeiDou 単体より混合解析同様に座標の精度が向上することが確認できた。 なお、アンビギュイティ決定モードを「Continuous」にした場合、L1 一周波解析では擬 似距離 ISB、搬送波位相 ISB 両方を補正することで 100%近いフィックス解が得られたが、 二周波解析では BeiDou と GPS、BeiDou と GLONASS の組み合わせで 20%以下となる現 象がみられた。BeiDou と Galileo の組み合わせでは共通の信号が L1 一周波のためこの現象 はみられず、BeiDou と QZSS の組み合わせでは共通の信号が二周波であるが、GPS や GLONASS のようなフィックス率の低下はみられなかった。この原因についてはまだ不明で あり、原因解明にはより詳細な調査が必要である。 表 2-65 ISB 補正基線解析結果(BeiDou.... BeiDou と他の衛星系間で位相差を取ることを可能にする方法 2.2 の「BeiDou の系統誤差の補正方法」のこれまでの調査結果を踏まえ、BeiDou と 他の衛星系間で位相差を取ることを可能にする方法について検討した。 BeiDou と他の衛星系間の統合解析では、擬似距離 ISB、搬送波位相 ISB を補正する ことでキネマティック基線解析においてフィックス解を得ることができた。しかし、受 信機機種にもよるが表 2-74 の通り搬送波位相 ISB が受信機再起動によって変化するた め、事前に推定した補正値をテーブルとして与えて補正することができない。この解決 策としては、BeiDou と他の衛星系の組み合わせでは衛星系間で位相差を取らない混合 解析とすることで、擬似距離 ISB、搬送波位相 ISB とも発生しないため、受信機再起動 で変化する搬送波位相 ISB を考慮する必要がなくなる。 なお、平成 25 年度の業務での調査結果では GLONASS と他の衛星系間で受信機再起 動により搬送波位相 ISB が変化し、本業務では BeiDou...
