Time of Perigee Passage Solution

STEP 0: Pre-Calculation Summary

Formula Used

Perigee Passage = Time in Minutes-(Mean Anomaly/Mean Motion)
L_perigee = t_min-(M/n)
This formula uses 4 Variables

Variables Used

Perigee Passage - (Measured in Second) - Perigee passage refers to the moment when a satellite reaches its closest point to Earth during its orbit.
Time in Minutes - (Measured in Second) - Time in Minutes is the time measurement in minutes which is equivalent to 60 seconds.
Mean Anomaly - (Measured in Radian) - Mean Anomaly is the fraction of an elliptical orbit's period that has elapsed since the orbiting body passed periapsis.
Mean Motion - (Measured in Radian per Second) - Mean Motion is angular speed required for a body to complete an orbit, assuming constant speed in circular orbit that takes same time as variable speed elliptical orbit of actual body.

STEP 1: Convert Input(s) to Base Unit

Time in Minutes: 20 Minute --> 1200 Second (Check conversion here)
Mean Anomaly: 31.958 Degree --> 0.557772322352243 Radian (Check conversion here)
Mean Motion: 0.045 Radian per Second --> 0.045 Radian per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

L_perigee = t_min-(M/n) --> 1200-(0.557772322352243/0.045)

Evaluating ... ...

L_perigee = 1187.60505950328

STEP 3: Convert Result to Output's Unit

1187.60505950328 Second -->19.7934176583881 Minute (Check conversion here)

FINAL ANSWER

19.7934176583881 ≈ 19.79342 Minute <-- Perigee Passage

(Calculation completed in 00.020 seconds)

FAQ

What is Time of Perigee Passage?

The Time of Perigee Passage formula is defined as the time of the satellite passage through the closest approach to the earth and is represented as L_perigee = t_min-(M/n) or Perigee Passage = Time in Minutes-(Mean Anomaly/Mean Motion). Time in Minutes is the time measurement in minutes which is equivalent to 60 seconds, Mean Anomaly is the fraction of an elliptical orbit's period that has elapsed since the orbiting body passed periapsis & Mean Motion is angular speed required for a body to complete an orbit, assuming constant speed in circular orbit that takes same time as variable speed elliptical orbit of actual body.

How to calculate Time of Perigee Passage?

The Time of Perigee Passage formula is defined as the time of the satellite passage through the closest approach to the earth is calculated using Perigee Passage = Time in Minutes-(Mean Anomaly/Mean Motion). To calculate Time of Perigee Passage, you need Time in Minutes (t_min), Mean Anomaly (M) & Mean Motion (n). With our tool, you need to enter the respective value for Time in Minutes, Mean Anomaly & Mean Motion and hit the calculate button.
