Reference Time in Julian Centuries Solution

STEP 0: Pre-Calculation Summary
Formula Used
Reference Time = (Julian Day-Julian Day Reference)/Julian Century
tref = (JD-JDref)/JC
This formula uses 4 Variables
Variables Used
Reference Time - Reference Time is the time period for which statistical results are collected or calculated and to which, as a result, these values refer.
Julian Day - (Measured in Second) - Julian Day refers to a system of timekeeping that is commonly used to synchronize various operations and events.
Julian Day Reference - (Measured in Second) - The Julian day reference is a system used to represent dates and times in a standardized format.
Julian Century - (Measured in Second) - Julian Century is used to simplify calculations of the positions of celestial objects in the sky, such as the sun, moon, and planets.
STEP 1: Convert Input(s) to Base Unit
Julian Day: 427 Day --> 36892800 Second (Check conversion here)
Julian Day Reference: 7 Day --> 604800 Second (Check conversion here)
Julian Century: 300 Day --> 25920000 Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
tref = (JD-JDref)/JC --> (36892800-604800)/25920000
Evaluating ... ...
tref = 1.4
STEP 3: Convert Result to Output's Unit
1.4 --> No Conversion Required
FINAL ANSWER
1.4 <-- Reference Time
(Calculation completed in 00.004 seconds)

16 Satellite Orbital Characteristics Calculators

Position Vector
Go Position Vector = (Major Axis*(1-Eccentricity^2))/(1+Eccentricity*cos(True Anomaly))
Kepler's First Law
Go Eccentricity = sqrt((Semi Major Axis^2-Semi Minor Axis^2))/Semi Major Axis
Mean Anomaly
Go Mean Anomaly = Eccentric Anomaly-Eccentricity*sin(Eccentric Anomaly)
True Anomaly
Go True Anomaly = Mean Anomaly+(2*Eccentricity*sin(Mean Anomaly))
Universal Time
Go Universal Time = (1/24)*(Time in Hour+(Time in Minutes/60)+(Time in Seconds/3600))
Reference Time in Julian Centuries
Go Reference Time = (Julian Day-Julian Day Reference)/Julian Century
Julian Day
Go Julian Day = (Reference Time*Julian Century)+Julian Day Reference
Julian Century
Go Julian Century = (Julian Day-Julian Day Reference)/Reference Time
Nominal Mean Motion
Go Nominal Mean Motion = sqrt([GM.Earth]/Semi Major Axis^3)
Mean Motion of Satellite
Go Mean Motion = sqrt([GM.Earth]/Semi Major Axis^3)
Local Sidereal Time
Go Local Sidereal Time = Greenwich Sidereal Time+East Longitude
Kepler's Third Law
Go Semi Major Axis = ([GM.Earth]/Mean Motion^2)^(1/3)
Range Vector
Go Range Vector = Satellite Radius Vector-[Earth-R]
Orbital Period of Satellite in Minutes
Go Orbital Period in Minutes = 2*pi/Mean Motion
Anomalistic Period
Go Anomalistic Period = (2*pi)/Mean Motion
Universal Time Degree
Go Universal Time Degree = (Universal Time*360)

Reference Time in Julian Centuries Formula

Reference Time = (Julian Day-Julian Day Reference)/Julian Century
