Scheduling satellite contact using AWS Ground Station and Python SDK
Manually navigating the AWS Ground Station Command Line Interface (CLI) requires knowledge of long Amazon Resource Names (ARN) for the mission profile and satellite, which can be a challenge to find. With this interactive CLI tool you now have a simple way to schedule AWS Ground Station satellite contacts directly from your terminal.
This tool provides an alternative to using the web console for contact scheduling. The utility uses the python boto3 software development kit (SDK) to call the AWS Ground Station APIs. This tool streamlines the contact scheduling process by taking the user on a guided contact scheduling experience. It expands on the functionality available in the AWS Ground Station web console by:
- Scheduling/canceling multiple contacts at the same time, versus just one at a time in the web console
- Filtering contacts based on maximum elevation, versus no filtering based on maximum elevation in the web console
- Scheduling contacts with precise duration, versus only being able to schedule the whole pass in the web console
The tool has three functions:
- Schedule contacts with elevation and duration requirements
- Show contacts of the following types:
“SCHEDULED”, “SCHEDULING”, “FAILED_TO_SCHEDULE”, “AWS_CANCELLED”, “CANCELLED”, “COMPLETED“, ”FAILED“, ”AWS_CANCELLED“, ”AWS_FAILED“, ”CANCELLED“, ”FAILED_TO_SCHEDULE”
- Cancel scheduled contacts
Contacts with duration shorter than the whole craft pass are scheduled in the middle of the pass to maximize craft elevation.
The tool uses default AWS CLI credentials/region stored in the /.aws folder. Learn how to set up your AWS CLI.

Examples of how to use the interactive AWS CLI tool for AWS Ground Station
The first example in Figure 1 is of scheduling two contacts at the same time with elevation and duration requirement.
