Class: Technology. Nation: Europe. Agency: ESA.

Launch vehicle test. Technological Capsule (CAT). Principal mission of the technological capsule (with ballast), which was equipped with batteries having a lifetime of approximately 8 orbits, was to transmit back to earth technological data on the first developmental flight L01 of the ARIANE launch vehicle. When the batteries were exhausted, the capsule ended its radio transmissions, and it is now inoperative but still in orbit.


Specification


CAT Chronology


24 December 1979 CAT 1 Launch Site: Kourou . Launch Vehicle: Ariane 1. Mass: 1,602 kg. Perigee: 125 km. Apogee: 14,047 km. Inclination: 17.8 deg.

Launch vehicle test. Technological Capsule (CAT). ESA registration number: ESA/79/2. Principal mission of the technological capsule (with ballast), which was equipped with batteries having a lifetime of approximately 8 orbits, was to transmit back to earth technological data on the first developmental flight L01 of the ARIANE launch vehicle. When the batteries were exhausted, the capsule ended its radio transmissions, and it is now inoperative but still in orbit.


23 May 1980 CAT Launch Site: Kourou . Launch Vehicle: Ariane 1. FAILURE: Failure.
19 June 1981 CAT 3 Launch Site: Kourou . Launch Vehicle: Ariane 1. Perigee: 227 km. Apogee: 29,240 km. Inclination: 10.6 deg.

Launch vehicle test payload. Technological capsule. ESA registration ESA/81/02. Launch time 1233:03 UT. The technological capsule, equipped with batteries for a lifetime of about six orbital revolutions, transmits to earth technological data about test flight L-03 of ARIANE. After di scharge of the battery the capsule will stop its transmissions and remain in orbit on inactive status. Frequency 136-138 MHz (transmission until 65h after launch only). Projected time of reentry 1986.


20 December 1981 Tech. capsule Launch Site: Kourou . Launch Vehicle: Ariane 1. Perigee: 199 km. Apogee: 36,051 km. Inclination: 10.6 deg.

Ariane L-04 technological capsule, ESA designator ESA/81/04. The technological capsule, equipped with batteries for a lifetime of about 6 orbital revolutions (65h), transmits to earth technological data about test flight L-04 of Ariane. After discharge of the battery the capsule will stop its transmissions and remain in orbit in an inactive status. Frequency 136-138 MHz, projected time of reentry before 1990.
