摘要：
Due to hypersonic vehicle's high velocity, large attitude maneuver and wide envelope, unreasonable antenna layout will lead to bad performance of satellite navigation, such as the reduction of received GNSS satellite numbers or even non-positioning. In this paper, a GNSS antenna layout evaluation method for hypersonic vehicle is proposed to handle this problem. A hypersonic vehicle mission simulation and GNSS antenna layout evaluation environment based on STK/Matlab is established to validate the method, including the aircraft's typical trajectory and attitude data, navigation satellite constellation, and two different antenna layout models. The advantages and disadvantages of the two antenna layouts are analyzed. Based on the proposed method, the proper antenna layout which meets the flight safety and mission requirements is found out by calculating the receiving satellite numbers and PDOP of the GNSS receiver.
