TRAJECTORY MAKER FEATURES
Trajectory Maker is a professional simulation and design tool for scientists
and engineers involved in mission analysis and orbital operations.
1. Trajectory Maker generates precision trajectories
o Earth orbiting satellites.
o Space probes.
o Ballistic missiles.
2. Four Acceleration Models
o Keplerian two-body motion.
o Gravity perturbations.
o Atmospheric drag perturbations.
o Gravity perturbations with atmospheric drag effects.
3. Graphics Visualization
o Displays trajectory ground traces as they are generated.
o Displays three conformal map projections.
o Displays altitude history trend.
o Displays time and altitude numerical data.
4. Five Numeric Output Formats
o Geographic coordinates: geodetic latitude, longitude and
altitude.
o Common radar coordinates: range, azimuth, elevation and range
rate.
o Geospherical inertial coordinates: radius vector magnitude,
right ascension, declination, velocity magnitude, velocity
azimuth and flight path angle.
o Earth centered inertial coordinates: rectangular position,
velocity and acceleration.
o Echoed input data with period, nodal regression rate and line
of apsides rotation rate, initial true anomaly, eccentric
anomaly, mean anomaly, energy, altitude bounds, Kepler flight
time, solar data, etc.
5. User Controlled Time Parameters
o Date and time of injection.
o Mission duration time.
o Granularity of computations.
o Output sampling frequency.
6. Initial State Vector Input Options
o Classical orbital elements.
o Earth-centered-inertial coordinates.
7. English or Metric Units
TRAJECTORY SCAPE FEATURES
Trajectory Scape is a companion program that may be used to display several
trajectories, created by Trajectory Maker, on various world map projections.
1. Views Multiple Trajectories
2. Five World Map Presentations
o Mercator projection.
o Stereographic projection of the northern hemisphere.
o Stereographic projection of the southern hemisphere.
o Hammer-Aitoff equal area projection.
o Mollweide equal area projection.
3. Three Map Resolutions
o Fine resolution.
o Medium resolution.
o Coarse resolution.
4. Three Central Viewing Regions
o Greenwich meridian.
o American Region.
o Soviet Region.
5. Both Programs are easy to install and use.
These two programs are powerful analysis tools offered at an excellant value.
