这次起飞的翼龙-2H 无人机是从贵阳附近起飞的,抵达河南上空后依然能提供 5 小时的滞空时间,算上来回飞行时间和预案里预留的任务冗余,整个滞空能力至少是 20 小时往上。

一个被经常问到的问题是「为什么只出动了一架」而非「多架次接力保证全时覆盖」,因为现在只有这一架,真的没有多。

这个项目中航去年年中才做出来,还在进行进一步的测试和改进,要把基站上天、信号中继、组网等各种功能全部集成在吊舱里,还要做到极高的可靠性、可用性,还要能保证能耗不高,能配合长时间滞空的任务需要,真的非常难。(初号机永远滴神!)

这次河南的灾情对这套系统可以说是第一次实战级别的检验,而相信这个项目投产以后,我们的应急航空能力也会大幅提高。如果下次有需要的话,可能起飞的就不是一架无人机,而是一个能提供全时通讯能力覆盖的机群了。

河南加油,中航加油。

Telegram auto-delete message, expiring invites, and more

elegram is updating its messaging app with options for auto-deleting messages, expiring invite links, and new unlimited groups, the company shared in a blog post. Much like Signal, Telegram received a burst of new users in the confusion over WhatsApp’s privacy policy and now the company is adopting features that were already part of its competitors’ apps, features which offer more security and privacy. Auto-deleting messages were already possible in Telegram’s encrypted Secret Chats, but this new update for iOS and Android adds the option to make messages disappear in any kind of chat. Auto-delete can be enabled inside of chats, and set to delete either 24 hours or seven days after messages are sent. Auto-delete won’t remove every message though; if a message was sent before the feature was turned on, it’ll stick around. Telegram’s competitors have had similar features: WhatsApp introduced a feature in 2020 and Signal has had disappearing messages since at least 2016.
