1. First satellite of world
5. these satellites can cover high altitudes
7. elevation for geostationary orbit with equator
10. provides an average value of angular position of satellite wrt perigee
11. when day and night are of equal lengths
12. angle on horizontal plane in antenna look angles
13. Orbit direction is opposite to earth’s rotation
14. point on earth vertically under satellite
16. The point where the orbit crosses the equatorial plane going from south to north
19. horizontal lines on earth are called
20. is the rotation of the vehicle about its vertical axis
22. Area covered by satellite

2. the equipment used to provide the service for which the satellite has been launched
3. second stage of satellite launching
4. Rotation of a geosynchronous satellite means
6. orbit is direction as earth’s rotation
