![]() ![]() You have a good start on the inspector satellite with the LEO satellite you just built. Set the Maximum time between orbit points to ten (10) sec.Run ( ) Astrogator to propagate the satellite.Now that you have the satellite ready you can propagate it. Propagate the Satellite and Clean Up Graphics Change the Propagation duration stopping condition to two (2) days.Įxample LEO orbit values.Change the Initial State ( ) to the following LEO orbit.Enter the following in the Satellite's properties.Add a satellite ( ) using the Define Properties ( ) method in the Insert STK Objects ( ) tool.Either accept the default start time and add two days (+2 days) or use the specified times below Set the analysis period to the following.Create a new scenario and call it LEO_Rendezvous.Model the World!īefore you can begin with any analysis, you need to create a scenario and add a satellite. ![]() The starter scenario was used for a virtual training to speed things up. The starter scenario isn't needed for the tutorial because the steps in the tutorial walk you through how to get the starter scenario. The video references a starter scenario that can be found in the SDF. Video GuidanceWatch the following video, then follow the steps below incorporating the systems and missions you work on (sample inputs provided). Generate and evaluate relevant data sets.Model a drift approach, Vbar hop, and target a NMC.Model a target satellite and a maneuvering (RPO) satellite.Upon completion of this tutorial, you will be able to: Introduction to Satellite Maneuver Planning with STK Astrogator.It is recommended you go through the following tutorials to become familiar with Astrogator, if you are not already: This tutorial assumes you have some working knowledge of Astrogator. As mentioned above, this tutorial will not result in a minimum Delta-V solution, as osculating orbital effects are not considered in determining optimal departure and transfer times. It is not meant to cover or address all of the nuances regarding this type of relative orbit. This tutorial is intended to address a common RPO mission requirement, while providing a basic understanding of Astrogator's techniques. It is worth noting that there is nothing trivial about RPO. We’ll create a Mission Control Sequence (MCS) to perform a non-optimal transfer to the target satellite, and a maneuver to enter into a Natural Motion Circumnavigation (NMC) relative orbit. You will model two satellites already in the same plane, with an “Inspector Satellite” trailing a “Target Satellite” in True Anomaly, and will target two in-plane burns to approach and subsequently circumnavigate the target. You will follow some basic steps in modeling missions of one satellite approaching another already in orbit using Astrogator. STK’s Astrogator capability has a very robust feature set that allows for complex RPO mission planning and requires significant expertise to efficiently and effectively plan an RPO mission. An RPO mission planner with minimal training wants to plan an RPO mission. Rendezvous and proximity operations (RPO) mission planning can be a very complex process. This lesson covers the following STK Capabilities: It is acceptable to have different results. The results of the tutorial may vary depending on the user settings and data enabled (online operations, terrain server, dynamic Earth data, etc.).
