摘要

目前在加拿大有超过700个全球导航卫星系统(GNSS)参考站(主动控制站- ACSs)积极广播校正。自21世纪初以来,这一数字一直在持续增长。2009年,加拿大地理信息委员会(CCOG)的联邦、省和地区成员认识到,GNSS校正数据的消费者几乎没有能力核实服务提供商是否遵循了确保其工作质量的最佳做法。测量员通常会划定财产边界或确定具有重大经济价值的民用基础设施的位置,因此在没有质量保证的情况下依赖另一方被视为一种重大风险。此外,这种对商业ACSs进行GNSS校正的新依赖对加拿大位置值的一致性构成了威胁。为了解决这一问题,CCOG责成其加拿大大地测量参考系统委员会(CGRSC)制定一项计划,以描述、验证和提供业界使用的GNSS校正服务的认证。本文总结了加拿大自然资源部(NRCan)高精度GNSS服务合规计划的发展,以及它如何使加拿大的专业测量师受益。

NRCan’s Compliance Program for high accuracy, GNSS services: ensuring compatibility with the Canadian Spatial Reference System
There are currently over 700 Global Navigation Satellite System (GNSS) reference stations actively broadcasting corrections (Active Control Stations — ACSs) in Canada. This number has been consistently growing since the early 2000s. In 2009, the federal, provincial, and territorial members of the Canadian Council on Geomatics (CCOG) recognized that consumers of GNSS corrections data had very little ability to verify that service providers were following best practices to ensure the quality of their work. It is common for surveyors to delineate property boundaries or to define the location of civil infrastructure with significant economic value, so being dependent upon another party without quality assurance was perceived as a major risk. Additionally, this new dependence upon commercial ACSs for GNSS corrections posed a threat to the consistency of position values in Canada. To address this concern, CCOG tasked its Canadian Geodetic Reference System Committee (CGRSC) with developing a plan to describe, validate, and provide certification of the GNSS corrections services consumed by industry. This paper summarizes the development of Natural Resources Canada’s (NRCan) Compliance Program for High Accuracy, GNSS Services, and how it can benefit professional surveyors across Canada.

期刊介绍: Geomatica (formerly CISM Journal ACSGC), is the official quarterly publication of the Canadian Institute of Geomatics. It is the oldest surveying and mapping publication in Canada and was first published in 1922 as the Journal of the Dominion Land Surveyors’ Association. Geomatica is dedicated to the dissemination of information on technical advances in the geomatics sciences. The internationally respected publication contains special features, notices of conferences, calendar of event, articles on personalities, review of current books, industry news and new products, all of which keep the publication lively and informative.
