Time scales and reference systems chapter

[jorgepiloto]

Time scales is a very important topic that is not covered on many astrodynamics or orbital mechanics books. I would like to include this after the introductory chapter #1. Following models should be covered:

• Time scales

• [ ] Universal time
• [ ] Julian Date
• [ ] Sidereal Time
• [ ] Atomic Time
• [ ] Dynamical Time

• Reference systems

• [ ] Celestial Equatorial Systems
• [ ] Terrestrial Equatorial Systems
• [ ] Celestial Ecliptic Systems

Some algorithms may be included in this chapter together with astropy and poliastro examples if required.

A good reference book for this which includes beautiful drawings is:

• Methods of orbit determination for the micro-computer, Dan Boulet
