Description

These data were obtained from a software-defined radio receiver (SDR) and Raspberry Pi single-board computer running a modified version of dump1090 software in Niswonger Hall at the Lafayette, Indiana, airport (KLAF). The logging device recorded received Mode S and Mode C transponder data over a period of 60 days in the accompanying 60 .csv files between April 1 and May 30, 2016.

The antenna was located at approximately:

40°24′58.08″N

86°55′46.10″W

The following fields are contained in each row of the file:

  • tstamp: Date and time recorded to the nearest minute
  • t.hexid: ICAO 24 bit address
  • m.ident: Aircraft tail number
  • alt: pressure altitude of aircraft
  • t.lat: Latitude of aircraft expressed in decimal degrees
  • t.long: Longitude of aircraft expressed in decimal degrees
  • sig1…sig8: The last 8 reported signal strengths
  • Signal.Avg: The average of sig1..sig8
  • ActDist: Computed distance in miles between ground received and aircraft using aircraft reported position
