# Satellite Slant Range Calculator

The slant range is the distance between the two points, from radar to the target. The geocenter is the description of the universe where the earth is in the center. The angle between the horizontal plane and the line of sight is called as elevation angle. Here is the online Satellite Slant Range Calculator to calculate slant range satellite communication. Enter the inputs values, the tool will update you the distance between the geocentric & satellite and slant range of the satellite.

#### Formula:

r = h + B
D = √ [(B x Cos(ε))^{2} + r^{2} - B^{2}] - (B x Cos(ε))
**Where,**
h = Distance Between GND Station and Satellite
B = Distance Between Geocenter and Ground Station
ε = Elevation Angle
r = Distance Between Geocenter and Satellite
D = Satellite Slant Range
### Example:

Calculate the satellite slant range based on the Distance Between GND Station and Satellite of 1000 km, Distance Between Geocenter and Ground Station of 200 km and the elevation angle of 45°.

#### Solution:

r = h + B

= 1000 + 200

= 1200 km

D = √ [(B x Cos(ε))^{2} + r^{2} - B^{2}] - (B x Cos(ε))

= √ [(200 x Cos(45))^{2} + 1200^{2} - 200^{2}] - (200 x Cos(45))

= 1082.807 km
