While cruising, the system needs to fix on at least one object per minute to avoid drifting more than 50 metres off course. That's good enough for reconnaissance, if not precision bombing.
在巡航过程中，该系统需要每分钟至少锁定一个物体，以避免偏离航线50米以上。这对于侦察来说已经足够了，即使不能进行精确轰炸。
To improve accuracy and allow night flights, MindCraft.ai is incorporating a heat-sensing infrared camera. The upgrade should be ready by the end of this year.
为了提高准确性并允许夜间飞行，MindCraft.ai正在整合一台热感应红外摄像头。升级应该在今年年底前完成。
MindCraft.ai has also developed a NOGPS feature for what they call semi-automated autonomous targeting.
MindCraft.ai还开发了一项NOGPS功能，用于他们所谓的半自动自主瞄准。
Now being tested by clients, it allows drone operators to lock onto targets they spot in live video.
现在正在接受客户的测试，它允许无人机操作员锁定他们在实时视频中发现的目标。
If jamming subsequently severs the video link, the system delivers the munition without further human input.
如果干扰随后切断了视频链接，系统将无需进一步的人工输入即可投放弹药。
This function is valuable because jamming typically gets worse as drones approach enemy assets, says Mr Bosyi, who is also MindCraft.ai's lead data scientist.
这项功能很有价值，因为干扰通常会随着无人机接近敌方资产而变得更糟，Bosyi先生说，他也是MindCraft.ai的首席数据科学家。
MindCraft.ai's clients serially manufacture NOGPS models for a unit cost of between ?200 euros and 500 euros ($217-$550). Other systems cost more.
MindCraft.ai的客户批量生产NOGPS模型，单位成本在200欧元至500欧元（217美元至550 美元）之间。其他系统的成本更高。
Midgard says the componentry in its designs costs its manufacturer clients roughly 1,500 euros per unit.
Midgard表示，其设计中的组件每台成本约为1500欧元。
Their systems augment optical navigation with inertial data from accelerometers and gyroscopes like those used in smartphones.
他们的系统利用来自智能手机中使用的加速度计和陀螺仪的惯性数据增强光学导航。
To stay on course while cruising, Midgard's optical system needs to find a match between a terrain feature below and one in an onboard map only every 20 minutes or so.
为了在巡航时保持航向，Midgard的光学系统需要每20分钟左右匹配下方地形与机载地图。
Mr Varavin says that in ideal conditions precision is within several metres. That is comparable to GPS Demand for optical navigation is rising elsewhere, too.
Varavin先生表示，理想条件下，精度在几米之内。这与GPS相当，其他地方对光学导航的需求也在增加。
An Israeli firm called Asio reports brisk sales of an optical-navigation unit to the Israel Defence Forces and American firms. (Israel forbids exports of such technology to Ukraine.)
一家名为Asio的以色列公司报告称，以色列国防军和美国公司光学导航装置的销售情况良好。（以色列禁止向乌克兰出口此类技术。）
Introduced in 2021, the roughly $20,000 system, now dubbed AeroGuardian, weighs as little as 90g, draws just five watts of power and is accurate, in good conditions, within a metre or so, says David Harel, Asio's boss.
Asio的老板David Harel说，该系统于2021年推出，价值约20000美元，现在被称为AeroGuardian，重量仅为90克，功耗仅为5瓦，在良好条件下，精度在一米左右。
Asio expects sales this year to exceed $10m, double the figure for 2023.
Asio预计今年的销售额将超过1000万美元，是2023年的两倍。
Ukraine now sees optical navigation as a capability "focal point", says Anders Fogh Rasmussen, a former chief of NATO.
前北约秘书长安诺斯·福格·拉斯穆森表示，乌克兰现在将光学导航视为能力的“焦点”。
Ukraine's defence ministry has provided detailed terrain maps to Atlas Aerospace, a drone manufacturer in Riga, Latvia.
乌克兰国防部已向拉脱维亚里加的无人机制造商Atlas Aerospace提供了详细的地形图。
One way to better compare such maps with a drone's view is with lidar techniques, which record the travel time of laser pulses bounced off the ground.
激光雷达技术可以更好地比较此类地图与无人机视野，该技术记录从地面反射的激光脉冲的传播时间。
As lasers reduce stealth, Atlas designed a "virtual lidar" system.
由于激光降低了隐身性，Atlas设计了一种“虚拟激光雷达”系统。
This measures what founder Ivan Tolchinsky calls "optical flow"—the time it takes a pixel representing a terrain feature to transit the onboard camera's view.
该系统测量的是创始人Ivan Tolchinsky所说的“光流”——代表地形特征的像素传输到机载摄像头视野所需的时间。
Since an initial shipment in October, Atlas has delivered over 200 reconnaissance drones with such a system to Ukraine's army, and more have been ordered.
自10月首次发货以来，Atlas已向乌克兰军队交付了200多架配备此类系统的侦察无人机，并且已订购更多。
