| description | To allow simple retrofit of CRPA antennas to existing airframe designs as well as simple and inexpensive installations on new aircraft designs.SOLUTION: A satellite navigation system includes a digital controlled reception pattern antenna (DCRPA) subsystem and a global navigation satellite system (GNSS) receiver. The overall system is designed so that all radio frequency (RF) processing and digital sampling are incorporated in the DCRPA subsystem. The RF signal from each element of the DCRPA array is digitized separately. Then the resultant digital samples are combined into a single bit stream which is transmitted to the GNSS receiver. Preferably the GNSS receiver is a software defined radio. The arrangement allows the DCRPA subsystem and the GNSS receiver to be connected with a single coaxial cable.SELECTED DRAWING: Figure 1
【課題】既存の機体設計においてＣＲＰＡアンテナを簡単に改造し、新しい航空機設計への簡単で安価な設置を可能とする。【解決手段】デジタル制御受信パターンアンテナ（ＤＣＲＰＡ）サブシステム、及び全地球的航法衛星システム（ＧＮＳＳ）受信機を含む衛星航法システム。全体的なシステムは、すべての無線周波（ＲＦ）処理及びデジタルサンプリングがＤＣＲＰＡサブシステムに組み込まれるように設計されている。ＤＣＲＰＡアレイの各素子からのＲＦ信号は個別にデジタル化される。次いで、結果として得られたデジタルサンプルは、ＧＮＳＳ受信機に送信される単一のビットストリームに組み込まれる。好ましくは、ＧＮＳＳ受信機は、ソフトウェア無線である。この構成により、ＤＣＲＰＡサブシステムとＧＮＳＳ受信機を単一の同軸ケーブルと接続することが可能になる。【選択図】図１ |
