Resurs-P

Resurs-P[1] is a series of Russian commercial Earth observation satellites capable of acquiring high-resolution imagery (resolution up to 1.0 m). The spacecraft is operated by Roscosmos as a replacement of the Resurs-DK No.1 satellite.

The satellite is designed for multi-spectral remote sensing of the Earth's surface aimed at acquiring high-quality visible images in near real-time as well as on-line data delivery via radio link and providing a wide range of consumers with value-added processed data.

Spacecraft

The Resurs-P spacecraft was built by the Russian space company TsSKB Progress in Samara, Russia. It is a modified version of the military reconnaissance satellite Yantar-4KS1 (Terilen).[2] The spacecraft is three-axis stabilized. The design lifetime is no less than five years. The ground location accuracy is 10 metres (33 ft). The maximum daily imaging area is 1,000,000 square kilometres (390,000 sq mi).

Resurs is Russian for "Resource". The letter P stands for prospecting.[3]

gollark: <@!222424031368970240> If you're trying to make a sandbox which can't be broken even if you know it's there and are deliberately trying to remove it here are some things to watch out for- `getfenv`- `os.queueEvent` (if you run code which does basically any IO outside of the sandbox/with access to non-sandbox functions)- `debug`- `load` (it has some weird environment quirks)- `io` (due to, again, environment weirdness, depending on how you load the new FS API it might still use the regular one)- potential meddling with global APIs like `string` and/or metatables, to confuse your sandboxing codeand to hide it you probably also want to worry about- `debug`- `string.dump`- `error` (you can generate stack tracebacks in a really convoluted way using it, which could allow detecting the sandbox)- `error` (in some very convoluted way you can generate stack tracebacks using this and thus realize
gollark: Proper sandboxing is extremely hard. But if you want to protect against people/things not actively attempting to break it you can do quite well.
gollark: What happened to make you want to avoid programming anyway?
gollark: I don't really care enough about replacing DokuWiki now to pay money for it.
