ISO 17123-1:2010提供了评估和表示测量不确定度的一般规则的指南，用于ISO 17123-2、ISO 17123-3、ISO 17123-4、ISO 17123-5、ISO 17123-6、ISO 17123-7和ISO 17123-8的测试程序规范。 根据ISO/IEC指南99，ISO 17123-2、ISO 17123-3、ISO 17123-4、ISO 17123-5、ISO 17123-6、ISO 17123-7和ISO 17123-8仅规定了大地测量仪器的现场测试程序，而不确保可追溯性。为了确保可追溯性，拟提前在测试实验室对仪器进行校准。 ISO 17123-1:2010是基于ISO/IEC指南98-3的简化版本，涉及与大地测量测试特定领域相关的问题。

ISO 17123-1:2010 gives guidance to provide general rules for evaluating and expressing uncertainty in measurement for use in the specifications of the test procedures of ISO 17123-2, ISO 17123-3, ISO 17123-4, ISO 17123-5, ISO 17123-6, ISO 17123-7 and ISO 17123-8. ISO 17123-2, ISO 17123-3, ISO 17123-4, ISO 17123-5, ISO 17123-6, ISO 17123-7 and ISO 17123-8 specify only field test procedures for geodetic instruments without ensuring traceability in accordance with ISO/IEC Guide 99. For the purpose of ensuring traceability, it is intended that the instrument be calibrated in the testing laboratory in advance. ISO 17123-1:2010 is a simplified version based on ISO/IEC Guide 98？3 and deals with the problems related to the specific field of geodetic test measurements.
