1U, 3U, 6U: CubeSats

A basic CubeSat is a cube 10 cm a side: that is the unit, 1U. A 2U lines up two, a 3U three (about 10 × 10 × 30 cm), a 6U six, in two columns of three. Many amateur satellites are CubeSats; AO-91 fits in a single cube.

SSTV and SSDV

SSTV (slow-scan television): an analogue picture told by sound, line after line, in FM. The ISS's can be heard with a simple handheld and a decoder on the sound.
SSDV (Slow Scan Digital Video): a JPEG picture cut into numbered packets of 256 bytes, each with its check. A lost packet costs a few blocks, not the picture; the packets received by several stations add up.

The year in the designator

Every object launched gets an international designator: 1998-067A is the ISS — the launch year, the year's 67th launch, piece A. The orbital elements carry it on line 1 (98067A): the launch year of every satellite of the game is read there.

Where it comes from The dates, the countries or organisations and the operators are those of SatMe-PC's cards, in their words, asked the same way for every satellite; the international designators, AMSAT's bulletin's (or the site's elements'); the picture satellites, SatMe's SSTV and SSDV list (SatNOGS DB). The size is asked only when a source says it. What no source says (—) is not asked.
