ATLAS Scheduling

Task Requests , Flex Scheduler, Partner Site Scheduling, and Scheduler Bridge

SECURE SPACE ACCESS ANYTIME, ANYWHERE

At ATLAS we continuously work to make communicating with spacecraft simpler and more efficient for our clients. This is exactly why we developed our unique Flex Scheduler. Unlike traditional scheduling strategies, ATLAS offers a far more dynamic approach. Through simulation and forecasting, ATLAS identifies a certain number of minutes that are guaranteed to be available per month, per spacecraft, per ground station. And ATLAS’ Flex Scheduler accurately awards these minutes.

Our scheduler provides spacecraft operators with multiple options for scheduling their satellite contacts - called Tasks. All Tasks are scheduled on the ATLAS Federated Global Antenna Network by submitting Task Requests through our RESTful ® Freedom API. Task Requests contain information that constrains when and where a Task is preferred. This defines the behavior of our system during the contact.

Task Requests support the following scheduling and execution behaviors: Immediate, Exact, Minimum Duration, Flex (Before, After and Around), and Test.

Task Requests

Immediate: Task must be executed ASAP

Exact: Task requires a specific start & end time

Min. Duration: Task duration can be shortened to this threshold

Scheduler Attributes

Flex: Task may be scheduled during any visibility within a large window of time (hours)

Tes t : Task mode for playback of TM Recordings, stored in S3

Scheduling: Available from 1 min - 2 weeks

Guaranteed Available Minutes: Based on Freedom Forecaster, per spacecraft, per site, per month

Guaranteed Available Minutes: Clients requiring guaranteed minutes, typically will achieve those from Freedom Enterprise sites. Guaranteed minutes at any partner site is handled on a site-by-site basis, and is determined upon availability at the time of the Task Request.

FreeTime API: Provides clients with knowledge of Open/Free time windows and the utilization of each antenna in the network, including federated sites (when available). The FreeTime API allows clients to interrogate the ATLAS schedule and programmatically build Task Requests that are extremely likely to be successfully scheduled.

Potential Visibilities - Up to 24 Hours

Minimum Duration: The Flex Scheduler will always try to maximize Task Duration, up to the full Task Request. In cases of overlapping Task Requests, the Flex Scheduler will use the Minimum Duration field to flex the requests, yielding antenna time for everyone on our Federated Network. Setting the Minimum Duration above the Recommended Minimum may decrease the likelihood of successfully scheduling your Task Request. ATLAS recommends setting the Minimum Duration to the true minimum for your mission ConOps.

ATLAS is building and partnering to provide a global federated network of antennas. The ATLAS Federated Network is a network of networks that work together seamlessly, powered through AWS Cloud. ATLAS clients never worry about the differences between the network interfaces because ATLAS has designed our software to integrate them into a fused/unified mesh network. No one worries about sending a text message on AT&T and it being received correctly by a friend using Verizon, and now neither do spacecraft operators. The networks have integrated and become federated so that clients are completely unaware of the differences.

All the features of Freedom are offered at each Freedom Enterprise Site, and we offer as many as possible at all Partner Sites. Each Partner Site in our network is maximized, meaning we include every feature of Freedom that is possible to integrate at each ground site. This includes: Scheduling, Realtime TM/TC, data backhaul or recordings, Realtime metrics, just-in-time hardware configuration, and more.

The ATLAS Federated Network includes:

Freedom Enterprise Sites: Ground sites owned by ATLAS, or fully operated by ATLAS. We have the right to distribute all of the minutes on these antennas, and we are tightly integrated with the Hardware at each of these sites.

Digital Partner Sites: Ground sites where Freedom is fully integrated with the Partner Site via API(s). The interface is machine-to-machine (M2M) and automated. This model is typically used with Ground Station as-a-Service providers, ie. AWS Ground Station, ViaSat, etc.

Edge Partner Sites: Ground Sites where Freedom is fully integrated with the Partner Site via direct hardware access.

Through Freedom, the Flex Scheduler and Scheduler Bridge extend the reach of our network and scheduler to give clients the ability, and flexibility, to schedule the time needed for their pass. The Scheduler Bridge allows clients to schedule time on antennas - any ATLAS owned antenna, as well as our 3rd party partner sites.

The Scheduler Bridge seamlessly interfaces with any partner scheduler API, even schedulers that operate with a different ConOps than the ATLAS network. ATLAS clients are able to book time on any antenna managed by Freedom via a single API, both ATLAS owned (Freedom Enterprise) and both Digital and Edge partner antennas.

With the ATLAS Federated Network, enjoy the freedom of a scheduler, on a personal device near you, that fully realizes your mission ConOps.
