# Orbit of a satellite Calculator

## Calculates the orbital radius and period, and flight velocity from the orbital altitude. | ||

- Purpose of use
- Satellite navigation systems design
- Comment/Request
- It would be handy to have an indicator of the length of time a satellite is visible from Earth's surface, either from the horizon or - even better - above some elevation.

- Purpose of use
- Finding out how fast the 2nd stage on the latetst Rocket Lab Launch "They go up so fast" would need to be to stay in orbit
- Comment/Request
- Maybe let the user choose between km/s and km/h, as Rocket Lab reports their speed in km/h as well

- Purpose of use
- Analysis of Elon Musk's Starlink Internet over satellite service to determine theoretical data latency performance. Satellite orbit calculation should not affect latency, but "inquiring minds want to know" some of the peripheral details of putting up 550 or so low-earth satellites in phase one.

- Purpose of use
- Looking for generic formulas I can play with for various orbits, velocities, distance traveled, etc.
- Comment/Request
- I'd like to get more detailed formulas for orbits, altitude from planet with a given planet radius/diameter, velocity at given altitude, etc.

- Purpose of use
- Discussing orbital calculations with a friend of my daughter. Needed to check our calculations for correctness.

- Purpose of use
- grad school exam
- Comment/Request
- if you could write out the formulas... so we can have them to write into reports

- Purpose of use
- general curiosity
- Comment/Request
- would be great to be able to specify any parameter and calculate the others
