This is an updated version of the HTML Satellite Tracker. This is a stand alone HTML page with embedded STK Engine controls and a 2D window control. This will work with STK 9 and the previous version of this didnt handle time zones correctly, see below for details: I had to add a quick error check to determine if the GMT offset was a negative hour or a positive hour. If it was negative AND had an extra half hour offset (i.e. -8.5 hours) it now will handle that correctly where the old version would have simply added the half hour to the already negative offset making it an hour off (i.e. -8+.5= -7.5 versus -8-.5= -8.5). Also changed the directory where the Satellite database files were located as this changed from STK 8 to STK 9.

NMEA GPS Import Utilities

These utilities create STK Objects from a file containing NMEA sentenses. Specifically, $GPGGA and $GPRMC sentenses are required.

YPR Rates

This MATLAB script converts YRP angles in any sequence and the angular velocity vector into YPR rates. The algorithm uses analytical relationships to output YPR rates. Here are some things to keep in mind when using the script. The script is made for STK 9, but if you want to use it in STK 8, you need to change line 3 to: stkapp = actxGetRunningServer('STK8.application'); Because this grabs the current instance of STK, a satellite named Satellite1 must be in the script for this to work. You can change the satellite name in line 6 to the name of any vehicle in your scenario (aircraft, ground vehicle, etc), if you like. Another thing to note is that the script will give you YPR rates for the whole scenario time period. You can change this in line 12 in the Exec() method. Lastly, this script uses a matrix inverse function in line 60. If the matrix becomes poorly defined, it can introduce errors into the rates that are calculated. Feel free to add an algorithm to take care of this.

This application will take an input LLA and rates and propagate a missile forward from t0 to t1. Then it reports the missiles new LLA and rates at t1. Designed as an example of how to use atbLLAtoCBF function and then put the output into a Connect command.

Example of how to use MATLAB and COM with Data Providers

Uses COM interface to talk from MATLAB to STK. Uses some ExecuteCommand interfaces to setup a scenario. Then pulls a report from STK using the Object Model. Reports are extracted using 2 different approaches. First, a report is extracted between a start and stop time at a user defined step. Second, a report is extracted using a loop to request the data at specific individual times.

Body Mask Matrix mapping

This application takes an existing scenario and creates a point in the aircraft's body frame. The file will move the point around the body and determines if there's access at each point. The result is a matrix of 1's and 0's that indicate if there is access at that point around the object.

GPSConstellationPlugin

This GPSConstellationPlugin shows how to use the AGI Components in any .Net application. This example shows how to propagate GPS satellite orbits and provides methods that retrieve the orbital positions and velocities.

ReportGenerator

This was originally created to automate the process of determining access times from a selected group of facilities (in a constellation) to a satellite. Upon load, the html page ingests all of the available facilities and satellites in the scenario. The user is then able to multi-select facilities, and choose one satellite from a drop down list.

Navacc Scenario Creator

This utility creates a navigation accuracy scenario. Contains htm for both STKv8 and STKv9. The STKv9 version takes advantage of the new GPS Propagator. You can run these utilities using local files, or if you register the included ActiveX control (mpsControl.dll), you can point to urls.

HPOP Atmospheric Model Plugin

An HPOP force model plugin that will allow a user to define an altitude versus density table for propagation.

add multiple GroundVehicles from directions

this script allows you to specify an area where you want to add groundvehicles and it will load as many vehicles as specified. It is based on the "GroundVehicle from Directions" script (http://adn.agi.com/detailedView.cfm?resourceId=248) but uses a loop with random start/stop locations withing the specified area of interest. If you want MTOs instead of GroundVehicles, run this script first and then convert to MTOs using the object utilities (http://adn.agi.com/detailedView.cfm?resourceId=192)

ODTK maneuver input automation - VBS

This demonstrates how to add an InstantManeuver to an ODTK satellite using the VBScript interface.

ODTK collections and maneuvers - Perl

This shows you how to work with ODTK collections and maneuvers from Perl. Using Perl with ODTK has a few nuances that aren't as straight forward as when using a language like VBScript. One of the biggest issues is that the normal COM interfaces like to return things as Collections, not Arrays. So you have to make sure that your Perl code is expecting this. The Win32:OLE package can handle this - check out the documenation for it, particularly the use of the "in" keyword. . For maneuvers, the key is to know that all collections must implement the Count and Item interfaces. This is a OLE requirement. So we can use these when interfacing with Perl.

ODTK multi-day automatic processing

This code demonstrates one way of automating the processing of various batches of observations, including running the filter and smoother and generating some products. It was built for working with TDRS satellites and may reference some external files, so it won't run as-is. But it does demonstrate the interface and a possible workflow for automating the OD process.

Satellite overflight ESRI geoprocessing tool

This tool will operate in ESRI’s ArcToolbox - Geoprocessing framework and compute inter-visibility times from any point feature class to any of the earth science satellites. End users can pass in any point feature class, time duration and also specify an output file geodatabase. The tool will create an “OverflightFeatures” feature class inside of the specified file geodatabase. The feature class will contain the point features that have inter-visibility to any of the Earth Science satellites and also attributes of start, stop and duration of the inter-visibility.

VGT and Access Plugin Scripting

Integrating and Customizing STK with Plug-in Scripts This is the traing exercise from the 2204 User's Conference. It can also be found at https://www.agi.com/events/usersConference/2004/resources/trainingSession.cfm It uses the older plugin scripting interface to create custom a vector geometry tool vector and a custom access constraint. Examples are provided in VBScript and Matlab.

VGT plugin scripting custom vector

This scenario uses Perl or Matlab custom scripts to describe VGT vectors used to define the attitude of a spacecraft. The attitude of the spacecraft is sun-aligned until the boresight is 50 degrees off nadir, at which time it is locked to 50 degrees off nadir in the direction of the sun.
