The scope of this work is the development and evaluation of methodologies for improving UAV landing performance. The new methodologies are known as the Signal Prediction Algorithm (SPA), Active Heave Compensation (AHC) and the Landing Period Indicator (LPI). To promote interoperability, the methodologies do not require any specific ship equipment.<\/p>\n<p id=\"sp0120\">To evaluate the methodologies on an existing comprehensive UAV model, ShipMo3D was used to generate 105 sets of ship motion in sea states 2\u20136, headings 0\u2013180<sup>\u2218<\/sup>\u00a0and speeds 6\u201310 knots. Within the simulation the UAV, equipped with a Light Detection and Ranging (LIDAR) system, measures the ship motion\u00a0<em>in situ<\/em>. Using the Signal Prediction Algorithm (SPA), the UAV forecasts the ship motion and potential landing opportunities. The UAV can also use the SPA and the AHC system to maintain a safe hover position above the ship deck and determine landing trajectories with a specific touchdown velocity. The UAV can also employ the novel Landing Period Indicator (LPI) system which calculates an estimate of the ship&#8217;s energy and determines opportune times for safe landings.<\/p>\n<p id=\"sp0130\">The results indicate that the methodologies can improve the landing performance of autonomous helicopters. For the 105 sets of ship motion, using the combination of the SPA, AHC, and LPI improved landing success by up to 34% when compared to a common landing controller.<\/p>\n<p><\/p>\n<p>Check out other <a href=\"https:\/\/carleton.ca\/mdl\/publications\/\">publications<\/a> too.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We have a new publication in Aerospace Science and Technology: Abujoub S., McPhee J., Irani R.
