Hemisphere GNSS公司(以下简称Hemisphere)发布了新一代GNSS RTK引擎—雅典娜。据悉,这款全新的、面向未来的引擎将使Hemisphere的产品拥有更稳定、更精准的导航定位性能,且更具灵活性与可靠性,能适应多种弱信号、复杂环境。

Athena has yielded outstanding performed in virtually every environment where high-accuracy GNSS receivers can be used, the company stated. Hemisphere customers have tested Athena’s performance in long baseline, in open-sky environments, under heavy canopy, and in geographic locations experiencing significant scintillation.
内置了雅典娜引擎的高精度GNSS接收机,几乎在各种环境下都表现出卓越性能。据Hemisphere的客户测试结果显示,无论在开阔天空还是严重遮挡, 或是严重闪烁的地理位置下,以及长基线的测试中,雅典娜引擎都能表现良好。

Hemisphere has designed its new core engine to maximize the company's ability to excel at the rigorous GNSS requirements in multiple market segments, supplying its customers in machine control, survey and GIS, with a design for now and in the future, Hemisphere said in a statement.
Hemisphere的新核心引擎在设计上充分考虑了GNSS各个细分市场当前和未来的需求,最大化地提升了公司的能力,无论是现在还是未来,可以充分满足用户在机械控制、测量与GIS等领域的需求。

The release of Athena is a significant milestone for Hemisphere, which promises another new product entry into the market in the coming months.
雅典娜的发布对于Hemisphere是一个重要的里程碑,这意味着,Hemisphere将在未来几个月,向市场推出另一个代表行业顶尖水平的全新产品。

Features of Athena include these capabilities:
雅典娜主要性能

● Initialization time - A reliably consistent initialization performance, less than 15 seconds at better than 99.9 percent reliability.
 初始化时间—小于15秒的可靠一致的初始化性能,其可靠性优于99.9%。

● Robustness in difficult operating environments - Extremely high productivity under the most aggressive of geographic and landscape oriented environments for GNSS, while delivering up to 50 percent better performance in user tests matched against competitive systems.
 在恶劣环境下的坚固性(鲁棒性)—在极端恶劣的地理环境下,表现出优越的GNSS性能,与竞品相比,超出50%的性能。

● Performance on long baselines — Position stability for long baseline applications, with position quality often times exceeding the performance of other leading RTK systems on the market.
 长基线性能—长基线性能稳定,定位质量往往超过市场上其他领先的RTK系统的性能。

● Performance under scintillation — Sustained accuracy under ionospheric scintillation activities, providing one of the most reliable means to work with GNSS in scintillation-affected areas.
 电离层闪烁下的性能-在电离层闪烁活动下仍能持续精准,在受到电离层闪烁影响的环境中,提供最可靠的GNSS工作手段。

Rodrigo Leandro, Hemisphere's director of engineering, GNSS Positioning Systems, gave this description of the design process for Athena.
Hemisphere的GNSS定位系统工程总监Rodrigo Leandro博士,介绍了雅典娜的设计过程。

"Development of Athena started shortly after I came to Hemisphere in August of 2013. The company has been a leader in RTK solutions for many years. During those years, we focused in certain specific market segments such as agriculture, and under new leadership we determined there was a need to address a wider spectrum of market segments, with very high accuracy and feature rich capabilities built on the strong legacy platform we had already established. So, working with Mike Whitehead, the company CTO and our main RTK technologist, we identified the goal of reengineering our RTK engine to match the needs of RTK for the next 10 years, and to provide a foundation for future product development."
“2013年8月,我加入Hemisphere后不久就开始了雅典娜的研发,当时公司已经在RTK解决方案方面领跑多年。在那几年里,我们专注于某些特定的细分市场,如农业。在新团队的领导下,我们决定依托公司已有的强大平台,开发一个能适合更广泛细分市场、具有很高精度和功能丰富的产品。所以,我与公司首席技术官暨主要RTK技术专家--Mike Whitehead一起工作,确定了我们的RTK引擎再造目标是能匹配未来10年的市场需求,并为今后的产品开发奠定基础。”

Leandro continued, "As part of this, we made a decision to build an expanded, world-class software development team, pulling great talent from around the industry to create a group of 11 totally focused on what we should do to move GNSS technologies forward - looking at all types of positioning techniques, not just RTK. Athena is just the first result of that work to become publicly available - you will see plenty more coming from the team over time."
Leandro博士说:“作为计划的一部分,我们决定扩充人才建立一个强大的世界级软件开发团队,我们因此在全行业集结了11个优秀的人才,这些人完全专注于‘我们应该做些什么来驱使GNSS技术进步’的所有定位技术,而不只是RTK技术。雅典娜是我们这个团队公开的第一个结果,在未来,你们还会看到更多。”

"Looking at Athena specifically, we did a complete review, touching every part of the engine - from how we deal with the atmosphere, quality-control of the data, modeling the clock of the receiver, and so on, through to how to do external corrections, whether single-based or network-based. We even looked at and modified the receiver system, improving the multitasking architecture to more actively use the CPU for our computational work." Leandro said.
“具体而言,我们对雅典娜做了一个完整的回顾,涉及到该引擎的每一个部分--从如何处理大气、数据质量的控制、该接收机的时钟模型等等,到如何做外部校正,无论是基于网络还是单基。我们甚至研究并修改了接收机系统,改善了多任务架构,使其更为活跃地使用CPU为我们的计算工作服务。”Leandro说。

"I'm proud to say that the results of all that work match up to what we envisioned. RTK is a pretty mature technology at this point, so improving on what is available in the industry is a tough ask. However, our extensive competitive testing shows that the engine performs really well in terms of initialization, accuracy, and stability across a range of different environments, for instance in long baselines and under tree canopy, and our tests of scintillation are showing great results as well. Overall, we have seen excellent accuracy coming out of this engine compared to legacy as well as others in the marketplace. It's hard to win every single time in a toe-to-toe comparison, as systems and conditions differ in every test, but our broad testing shows us not only matching, but beating competitive systems pretty consistently."
“我很自豪地说,所有的工作的结果是符合我们的设想的。RTK是一个相当成熟的技术,在此基础上再做提升,对于整个行业都是一个棘手的问题。然而,我们广泛的对比测试表明,引擎(雅典娜)在初始化,精度方面和稳定性上表现非常好,并且在各样不同环境下,比如在长基线和树木遮挡下,我们对闪烁的测试结果也显示出良好的性能。总的来说,我们已经看到了这项引擎超出市场上同类产品的优越性能,为了测试出每一个细节指标的优胜性比较难,因为每一个测试系统和环境条件都不同,但我们的广泛的测试表明,我们各项性能均能超出竞争产品。”

"In our user base, both Hemisphere branded products and our OEM boards, we get exposed to a wide variety of applications and environments, from agriculture and marine, through machine control applications and survey systems," Leandro said. "Our goal from the start was to build a system that performed across that user base, and we are proud to say that we have delivered with Athena."
“Hemisphere品牌产品和OEM板卡的用户群,涉及到各种各样的应用程序和环境,从农业到海洋,到机械控制和测量系统,“Leandro博士说。“雅典娜引擎的设计目标从一开始就是要建立一个跨用户运行的系统,我们很自豪地说,我们已经通过雅典娜实现了这个目标。”

"In terms of availability, we want to get the Athena engine on as many current and legacy systems as possible, so our users have the best possible experience. However, we have also been improving the legacy engine as well, delivering gradual steps of improvement to our customers, so whatever version they are using, their experience should be much improved," Leandro concluded.
“在可用性方面,我们会尽可能多地将雅典娜引擎载入当前和已有的系统中,使我们的用户获取最好的体验。我们也一直在改进传统引擎,并提供给我们的客户试用不断改进的版本,所以无论他们使用的是什么版本,都会体验到更多的改善。”Leandro总结到。
