    • The present invention relates to satellite systems and more particularly, to the provision of novel systems and methods for verifying the in-orbit performance and operation of satellite communications subsystems. In contrast to traditional Payload IOT (in-orbit test), the invention operates without an uplink signal, by generating hardware-specific signatures using isolated, internally generated, thermal noise. It has been found that this noise provides a very stable, repeatable signal for testing. Prior to launch, a repeater command sequence is executed to generate a hardware-specific signature based on the internally-generated noise. The same repealer command sequence is then executed in-orbit to determine whether the hardware-specific signature has changed. The two signatures may be recorded and compared using a simple tool such as a spectrum analyzer. The methods also include novel use of the sun as a test signal source to calibrate equipment, to quantify atmospheric effects and to be used as an intermediate reference power level during measurements.
    • 本发明涉及卫星系统,尤其涉及提供用于验证卫星通信子系统在轨性能和操作的新颖系统和方法。 与传统的有效负载IOT(在轨测试)相比,本发明在没有上行链路信号的情况下通过使用隔离的内部产生的热噪声产生特定于硬件的签名来工作。 已经发现,这种噪声为测试提供了非常稳定,可重复的信号。 在启动之前,执行中继器命令序列以基于内部产生的噪声生成硬件特定的签名。 然后在轨执行相同的排斥器命令序列以确定硬件特定的签名是否已经改变。 这两个签名可能会被记录下来,并使用频谱分析仪等简单工具进行比较。 这些方法还包括将太阳作为测试信号源的新型用途,以校准设备,量化大气效应并在测量过程中用作中间参考功率电平。
