"The paper presents the concept and preliminary design of a single photon counting laser altimeter (lidar) dedi- cated for deep space rendezvous missions towards an asteroid. Overall estimated device weight and volume should not exceed 2 kg and 2 dm2 with the power consumption below 20 W. The altimeter range evaluation precision should be on the order of 5 cm. A complex software simulator of the entire laser ranging and photon counting link has been developed and verified. The simulator framework incorporates both the three-dimensional space- craft ight mechanics and topographical maps of the surface. Altimeter performance metrics are proposed and evaluated considering the topographical surface slope, environmental conditions, footprint coverage, gate range settings, and spacecraft-to-asteroid range and velocity. The asteroid topographical mapping and landing sce- narios are discussed; specific spacecraft-to-asteroid approach phases are simulated and range reading maximum repetition rate is determined for each operation phase. Photon counting approach enables additional functions to laser altimetry, namely the one way laser ranging and laser time transfers over interplanetary distances and absolute radiometry at the laser wavelength." . .
