Table 4-108. Intelsat-III F-7 Characteristics

Date of launch (location):

Apr. 22, 1970 (ETR)

Launch vehicle:

Thrust-Augmented Long-Tank Thor-Delta

Weight (kg):

146 (orbital)

Shape:

Cylindrical with an antenna mounted on one end

Dimensions (m):

1.04 height (1.98 with antenna)

1.42 diameter

Power source:

Solar cells plus NiCd batteries

NASA's role:

Launch vehicle and ground support (reimbursable)

Cooperating organizations:

NASA and Communications Satellite Corporation, representing the International Telecommunications Satellite Consortium (Intelsat)

Prime contractor:

TRW Systems Group

Objectives:

Commercial communications support for rive years from synchronous orbit above the equator (Atlantic link).

Results:

Successful; placed in lower transfer orbit than planned due to launch vehicle guidance system anomaly, but was successfully placed into synchronous orbit by the spacecraft's apogee motor.
