Earth horizon sensor
WebThe Earth’s horizon is detected by the sensor when α is within the range (ρ - ε, ρ + ε). The overlap area S in this range can be computed as a function of α, ε, and ρ as shown in Equation 21. For known values of ε and ρ, this relationship allows the sensor reading, which can be directly ...
