NASA 'YO LAUNCH CANADIAN SATELLITE

Canada's most advanced domestic communications satellite,/,NIK-3, is scheduled for launch by NASA from Cape Canaveral,Fla., on Friday, Dec. 15. The launch window that day extenc2sI'rom 7:21 to 8:59 p.m. EST.

This is a second generation satellite in a series oftencalled Telesat and ANIK-B is referred t o as Telesat-D byNASA. I t was preceded by ANIK-A1 (Telesat-A), launchedNov. 9, 1972; ANIK-A2 (Telesat-B), launched April 20, 1 9 7 3 ;and AN IK -A 3 (Tclesat-C), launched May 7, 1975,

The new satellite is to replace ANIK-A1 now positionedat 109 degrees west longitude over the equator, due south o fCalifornia. With a design lifetime of seven years, the ANIS-Bwill provide point-to-point voice, TV and data communicationstraffic to Canada's 10 provinces.

In addition to 12 commercial channels in the 6 and 4gigaHertz frequency bands, ANIK-B has four channels foroperation at the 12 and 14 GHz frequencies.

The entire capacity of the satellite's higher frequencybands will be leased to Canada's Department of Communicationsfor two years with an option for two additional years' use.Ciiese channels will be used for a series of 14 pilot projectslYrhich stem from the Communications Technology Satellite ( C T S ) ,3 joint U.S.-Canadian experimental satellite.

Included in these projects are social experiments suchas telemedicine, tele-education, teleconferencing and Eskimobroadcasting, all intended to further evaluate the use ofsatellites for reaching remote locations equipped with smallground stations.

Other, purely technical projects are designed to produceexperimental information about such subjects as signal propa-gation as well as power generation and usage.

The Delta launch vehicle will place ANIK-B into a highlyeiliptica7- rbit ranging in altitude from 185 to 3 5 , 7 8 7 kilo-meters ( 1 1 5 to 2 2 , 2 5 4 miles). The satellite will weigh9 2 2 kilograms ( 1 , 9 5 6 pounds) at liftoff, including an attachedsolid fuel rocket motor.

Several days after launch, at the seventh apogee (highpoint) of the elliptical orbit, the attached solid fuelrocket motor will be ignited to circularize the ANIK-B orbitat the geosynchronous altitude of 3 5 , 7 8 7 km ( 2 2 , 2 5 4 mi.).

At this geosynchronous orbit altitude, the velocity ofthe satellite matches the rotational speed of the Earth andANIK-B remains over the same location on the equator. Smallgas jets will 1-eep the satellite on "station" and properlyoriented towards the Earth to receive and retransmit signals.

LAUNCH OPERATIONS

The ANIK-B spacecraft will be launched from Complex 17 A,Cape Canaveral Air Force Station, Cape Canaveral, Fla., by athree-stage 3914 Delta launch vehicle.First Stage

The first stage is a McDonnell Douglas extended long-tank Thor booster with nine Castor IV strap-on Thiokol solid-fuel rocket motors. The Thor is powered by a Rocketdyne RS-27engine using liquid oxygen (LOX) and R P - 1 kerosene. The mainengine is gimbal-mounted to provide pitch and yaw control froml i f t o f f t o main engine c u t o f f (MECO). Roll control is pro-vided by Rocketdyne liquid fueled vernier engines.Second Stage

The second stage is powered by a TRW TR-201 liquid-fuel,pressure-fed engine also gimbal-mounted to provide pitch andyaw control through second-stage burn. A nitrogen gas systemuses eight fixed nozzles for roll control during powered andcoast flight, as well as pitch and yaw control during coastand after second-stage cutoff. Two fixed nozzles, fed by thepropellant-tank, helium-pressurization system, provide retro-thrust after third stage separation.Third Staae

The third stage is the TE-364-4 spin-stabilized, solid-propellant Thiokol motor. It is secured in a spintablemounted on the second stage. The firing of eight solid-propellant rockets fixed to the spintable accomplishes spin-up of the third stage spacecraft assembly.
