名前種類概要
createSatellites関数Make a group of satellites from their element sets.
DEFAULT_MAX_AGE_DAYS定数How old, in days, an element set may be at the moment shown before the satellite is left out: SGP4's error grows by a few kilometres a day, so a fortnight is as far as a picture should trust.
ElementSet型One satellite's orbital elements in the "GP" format that CelesTrak and Space-Track both serve as JSON (CCSDS OMM, one object per satellite).
MAX_SATELLITE_SPEED定数The fastest clock, in game seconds a second, at which the space view still places a group of satellites: above it the two moments SGP4 is run at would be too far apart to interpolate, so the group is hidden rather than drawn wrongly.
RefusedElementSet型A satellite the group could not use, and why: its elements did not start SGP4 (bad numbers), or it had decayed at its own epoch.
SatelliteInfo型What a page can tell a reader about one satellite at a moment: its name, its number, how old its elements are, how high and how fast it is.
SatelliteRef型A satellite chosen from a group: which group and which place in it.
Satellites型A group of satellites, ready to give positions for any moment: what createSatellites returns, and what <chikyu-space> takes in setSatellites.
SatellitesOptions型What createSatellites can be told.
