GetSatellite {spectator}

Gets info for a satellite

Description

Gets the information about the specified satellite, and possibly its current position.

Usage

GetSatellite(satellite, positions = TRUE)

Arguments

satellite

character name of the satellite for which to retrieve the trajectory. The satellite name is not case sensitive, and can be abbreviated as long as an unambiguous match can be obtained. Only one satellite can be queried at a time.

positions

logical indicating if the current position should be included. Default: TRUE

Value

If positions is FALSE, a single row data frame with following attributes:

id

integer identifier

name

character satellite name

norad_id

integer satellite catalog number

open

logical whether the data produced by the satellite is freely accessible

platform

character platform name

sensor_name

character name of the sensor available on the satellite

sensor_swath

integer swath width of the sensor available on the satellite

sensor_type

character type of the sensor available on the satellite (SAR or Optical)

If positions is TRUE, a single row object of class 'sf' with 'POINT' geometry type, with the same attributes as above.
