Online Application Options

Online application options control your ability to conduct online operations from within STK.

STK is configured to use online resources by default. The following features require internet access to obtain data that they require:

Connections for STK Online Services

For detailed information about how STK connects to the internet and how to maintain a connection, depending on your network environment, see Network Connections for STK Online Services.

If Allow Online Operations is disabled, features that require internet access will be disabled.

HTTP Proxy

A proxy server is a computer on your LAN that allows you to connect to the Internet without compromising the security of your internal network. If you want to access AGI web services and your organization uses a proxy server to connect to the internet, you will need to provide information about the proxy server to STK. If you are unsure how your Internet connection is configured, please consult your system administrator.

Configuring Proxy Settings in STK

Select System Proxy if connectivity to services is through a proxy.

Select Custom Proxy to specify the Server and Port information for your proxy server and, if necessary, your user name and password for it. Select Bypass proxy server for local addresses to connect directly to resources that Windows recognizes as local.

If there are addresses that you do not want to use the proxy to connect with, such as local resources that Windows fails to properly identify as local, enter those addresses in the Exceptions field.

Some proxy configurations do not work with online operations in STK.

Connection

Select Use HTTP Persistent Connections to use the same TCP connection to send and receive multiple HTTP requests/responses; deselect it to open a new connection for each request/response pair.

Select Use Secure HTTP Connection (HTTP/SSL) to use secure HTTP when communicating over the Internet where applicable. Note that not all services support HTTPS protocol, but the ones that do will use the HTTPS protocol if this option is enabled.

Version

Select Check for Software Updates When Starting STK to enable STK to check the Web for the latest STK version.

Select Prompt me to update every: to receive notifications from STK to remind you to check for a software update; select a frequency for the reminders from the drop-down menu.

Disabling or Enabling Online Operations for a Scenario

If you have a scenario currently loaded in STK and you change the Allow Online Operations setting, then you will need to save and reload the scenario to complete the process of disabling or enabling online operations.

Disabling

If you are disabling online operations in a scenario that was previously saved with them enabled, STK will then automatically update the scenario to disable online operations wherever they were being used.

The Allow Online Operations setting is an application setting, but the selection that is active when a scenario is saved is included in that scenario's data. Therefore, if you save a scenario with online operations disabled and then share it with someone who has online operations enabled, the scenario will retain the disabled selection that it was saved with.

Enabling

If you are enabling online operations from a scenario that was previously saved with them disabled, you will have to manually update the scenario to use these online features:

  1. Terrain Server - In the STK Globe Manager, click Add Terrain/Imagery, select Terrain Server, and then click Open.
  2. Bing™ Maps - In the 2D and 3D Graphics windows, click the Bing™ Maps toolbar button and change the selection to Bing™ maps.
  3. TLE or Catalog Source - If you are using a propagator that requires a TLE or catalog source (e.g., SGP4, GPS), open the Properties Browser for the object and, on the Orbit properties page, select AGI Server in the TLE Source or Catalog Source field.
