卫星地球站是一种用于与卫星通信的设备，其无线电设备的性能和质量对通信质量至关重要。噪声温度是衡量无线电设备性能的重要指标之一，因此需要对其进行准确的测量。

IEC 60510-1-5:1988规定了噪声温度测量的方法和程序。该标准要求在测量过程中，必须使用标准参考源，以确保测量结果的准确性和可重复性。同时，该标准还规定了测量设备的要求，包括测量仪器的精度、灵敏度和稳定性等。

在进行噪声温度测量时，需要注意以下几点：

1. 测量环境应该尽可能静音，以避免外界噪声的干扰。

2. 测量前应该对测量设备进行校准，以确保其精度和稳定性。

3. 测量过程中应该尽可能减少测量时间，以避免温度变化对测量结果的影响。

4. 测量结果应该记录在测量报告中，并标明测量条件和测量误差等信息。

IEC 60510-1-5:1988的实施可以有效提高卫星地球站无线电设备的性能和质量，保证通信质量的稳定和可靠。
