SPST 305 Orbital Mechanics

A blunted cone re-entry vehicle is returning to Earth with a re-entry flight path of 12 degrees and a velocity of 6.8 km/s. Use this information and data from Table 10-2 for Questions 1-4

Answer these 8 questions based on the following information: A rocket is launched from Kwajalein Missile Range in the Marshall Islands (9.24 degrees N, 267.29 degrees E) that is delivering a microsatellite to a parking orbit with a right ascension of the ascending node of 123 degrees at an inclination of 21.5 degrees. At the launch site, the current LST is 0200. 1. What is the inclination auxiliary angle? a=i=21.5 ° 2. What is the launch-direction auxiliary angle? sin γ= cosα cos LO ...

A satellite is launched into a low-Earth (parking) orbit with an altitude of 222 km and need to be moved into a geosynchronous orbit with an altitude of 38,622 km. Based on this information, perform the following 12 calculations: 222 km + 6378 km = 6600 km 38622 km + 6378 km = 45000 km 1. Determine the semimajor axis of the transfer orbit.

Answer the questions below based on the following information about a reconnaissance satellite: The satellite has an apogee altitude of 6,822 km and a perigee altitude of 1,542 km. The inclination is at 42 degrees, the right ascension of the ascending node is 85 degrees, and the argument of perigee is 52 degrees. The current true anomaly is 196 degrees. Be sure to carry all radian figures out to 4 significant decimal places. Special Note: Ensure your calculator mode (degrees or radians) mat...
