A dataset containing CPR's for 41 flights flying over Europe. One on 4th , 19 on 5th and 21 on 6th Feb 2017.
Format
A data frame with 53940 rows and 10 variables:
- cpm_id
CPR Message (CPM) line number
- tact_id
TACT Id, TACT (a.k.a. ETFMS) is an NM system
- timestamp_etfms
time of CPM reception by the ETFMS system
- timestamp_track
time of track
- block
block number. ETFMS internal use
- record
record number. ETFMS internal use
- entry_node_sac
Entry Node (EN) system area code (SAC). To avoid ambiguity in the exchange of Surveillance related data, each system using the ASTERIX data format gets assigned a unique identifier composed of two values called
SAC/SIC
. See https://www.eurocontrol.int/services/system-area-code-list- entry_node_sic
Entry Node (EN) system identifier code (SIC). To avoid ambiguity in the exchange of Surveillance related data, each system using the ASTERIX data format gets assigned a unique identifier composed of two values called
SAC/SIC
. The System Identification Code (SIC) is allocated nationally by the responsible Air Traffic Services Organisation. It identifies each individual system (surveillance sensor, surveillance data processing system, etc) within the respective area defined by the SAC. See https://www.eurocontrol.int/services/system-area-code-list- callsign
Callsign for the flight as provided in the FPL (Flight PLan). It may be the registration marking of the aircraft or the ICAO designator for the aircraft operating agency followed by the flight identification
- adep_icao
ICAO location identifier of the Airport of Departure (ADEP)
- ades_icao
ICAO location identifier of the Airport of Destination (ADES)
- eobt
Estimate Take-Off Date and Time (EOBT), the estimated time at which the aircraft will commence movement associated with departure
- longitude
longitude (decimal degrees)
- latitude
latitude (decimal degrees)
- flight_level
flight level of the aircraft. Flight levels are surfaces of constant atmospheric pressure which are related to a specific pressure datum, 1013.2 HP (Hecto-Pascal). The expression `Flight level times 100' is sometimes, not quite correctly, referred to as altitude in feet
- track_service
Determines whether the CPR is the first (Begin), an intermediate (Continuing) or the last (End) CPR sent by the corresponding system for the relevant flight. (Begin_And_End is also possible)
- ssr_code
A 4-Digit octal code used in the transponder to identify an aircraft (SSR Mode 3/A). See https://en.wikipedia.org/wiki/Aviation_transponder_interrogation_modes
- track_speed
calculated ground velocity (knots) based on the previous radar position
- track_heading
calculated heading of aircraft with respect to the magnetic North (decimal degrees)
- climb_rate
Climb (positive) or descend (negative) rate (knots)
- track_vertical_mode
a categorical value for the rate of climb, it can be one of CLIMB, DESCENT, LEVEL_FLIGHT or UNDETERMINED
- ifps_id
a unique flight plan identifier assigned by the IFPS system
- aircraft_address
a unique identification of the aircrafts frame (24-bit ICAO aircraft address)
