摘　　要：鉴于数字卫星新闻采集在电视传输的广泛应用,方便、快速和准确地寻找卫星变得非常重要。依靠iOS系统的设备,iOS卫星参数计算器软件能够轻易地在移动电话上使用,因此它也可以成为许多包含有卫星参数计算器功能的天线控制器的备件。首先,介绍了寻找卫星的几个参数,之后提出了核心计算方法。最后,仿真器测试和i Phone测试表明该软件可以支持快速寻找卫星。Considering digital satellite news gathering （DSNG） is widely used in TV transmission, the convenience, high speed and accuracy is important in satellite searching. Based on iOS instruments, the iOS satellite parameter calculator software, which is shown in this paper, can be easily used in cell phone, so that it can be a standby instrument for many antenna controllers which may always contain satellite parameter calculator. Firstly, in this paper, satellite searching parameters are introduced, then the ker- nel calculating method is described. At last, simulator tests and iPhone tests indicate that this software can support satellite search- ing rapidly.
