EXPECTED COURSE OUTCOMES: ENT 190

 

The purpose of this course is to give an overview of the space technology career field and how the technology is applied at NASA Goddard SFC in particular. This course is intended to be taken during the freshman year and is required of all Space Technology degree seekers. The mathematical content will be kept to a basic algebraic college level. Emphasis will be placed upon satellite technology.

 

The student will demonstrate a proficient knowledge of:

 

1.      Satellite-Launch vehicle and propulsion systems

        Satellite building blocks and structures

        Basic orbital mechanics including establishing an orbit and maneuvering

        Orbit maintenance

        Launcher performance (payload capabilities)

 

2.      Satellite power systems

        Solar arrays

        Storage cells

        Batteries

        Power conditioning and control electronics

 

3.      Spacecraft environment and remote sensing applications (as missions)

        Remote sensing principles

        Sensors as hardware

        Spacecraft effects caused by the space and launch environments

 

4.      Control and command of satellites

        Telemetry

        Tracking

        Navigation principles

        Antennas & sensors (link calculations, spectral power, BW, gain)

        Operations (ground and space)

        Tele-command (detection, decoding, routing)

 

5.      Satellite propulsion

        Basic thruster and propellant considerations

        Transducers that monitor launch

 

6.      Spacecraft performance testing and specifications

 

7.   Spacecraft systems, operational testing, and reliability considerations
