N2 - Considering the fuel consumption of the Mars lander, collision avoidance and elevation angle requirements in real missions, a three-phase Zero-Effort-Miss/Zero-Effort-Velocity (three-phase ZEM/ZEV) guidance law with elevation angle constraint is developed. The three-phase ZEM/ZEV guidance algorithm introduces altitude constraint for minimum safe altitudes and determines guidance parameters to meet it. By incorporating landing elevation angle constraint, trapezoidal constraint is proposed to provide solutions for complex landing scenarios. The three-phase ZEM/ZEV guidance algorithm meets the proposed trapezoidal constraint through the design of the second and third phases. Simulation tests show that the three-phase ZEM/ZEV guidance algorithm is reliable and robust. Also, parameter sensitivity analysis shows that its fuel efficiency is comparable to that of the classical ZEM/ZEV guidance.
