测绘装备野外计量保障系统的设计与实现

在野外条件下,测绘装备的伴随保障对于保证测绘装备技术性能、提升装备的保障能力,随时遂行各种测绘任务至关重要。本文系统地介绍了测绘装备野外计量保障系统的设计目的、原则和依据;车载式长度、角度、频率检定标准装置的组成和建立方法,野外维修保障设备的配备、计量保障方舱的重心偏移量。分析了野外条件下长度、角度标准的测量不确定度,证明了测绘装备野外计量保障系统完全可以满足检定和维修大地测量装备的要求。

Design and Implementation of the Field Metrological Support System of Mapping Devices

Under the field conditions,the support system of the mapping devices is important to guarantee the technical performance of the mapping devices,hoist the support ability,and complete every kinds of mapping tasks at any moment.This article systematically introduces the design objective,basis and foundation of the mapping devices filed metrological support system,the composition and construction method of the vehicle-carrying length,angle and frequency of the verification standard equipment,and the outfit of the filed maintenance support equipment.The measurement uncertainties of length,angle and frequency under the filed conditions,and the offset of the gravity center of the metrology support system are also analyzed.This paper also proves that the mapping device field metrological support system can totally meet the needs of the verification and maintenance of the geodesy equipment.
