About Complan®

Complan is an advanced satellite transmission engineering tool used for the design, analysis, optimization, and troubleshooting of satellite communications networks. Complan can simultaneously plan and optimize hundreds or thousands of links in an entire network, or even an entire satellite. No other commercially available tool comes close to matching its speed, accuracy, and level of detail.

Complan is used by satellite operators, satellite service providers, and end-user satellite network engineers operating on both commercial and military satellites. Anyone who manages a large amount of satellite capacity or who operates large or complex satellite networks will potentially benefit from the use of Complan. Utilizing Complan, capacity engineers can manage higher volumes of capacity than are possible with traditional link budget tools or in-house developed systems. They are able to quickly analyze their networks, perform complex trade-off analyses not otherwise practically possible, and optimize system design to make efficient use of space and ground-segment resources.

Interaction With Other Optimal Satcom Products
Enterprise Capacity Manager® (ECM™)
Complan is seamlessly integrated with Optimal Satcom’s ECM product. When a customer has both ECM and Complan, ECM forms a broad-based capacity management system, while Complan is used as an advanced transmission engineering and capacity optimization tool. ECM maintains all data and is used for routine capacity management. When Complan analysis is required, ECM can automatically synthesize and export the plan to Complan for further off-line analysis. Results of Complan can later be saved back to ECM as needed. When used together, Complan and ECM form a powerful capacity management system. ECM is a separately licensed product.
Customer Link Budget Tool (CLBT®)

Plans submitted by customers through CLBT can be imported into Complan, however, this is deprecated functionality, and will likely be removed in a later version of Complan.

Antenna Coverage Program (ACP™)
All map-based results generated by Complan are rendered in ACP, a full-featured mapping and visualization software that comes bundled with Complan. ACP does not need to be procured separately.
Sun Outage Calculator (SunOut™)
Complan uses SunOut to generate sun-outage reports. SunOut is an accurate sun outage prediction software that comes bundled with Complan. SunOut does not need to be procured separately.

Complan is available in two versions:

Complan Enterprise Edition can model multiple transponders within a plan and is suitable for satellite operators.

Complan Professional Edition is limited to modeling one (1) transponder per plan and is suitable for satellite service providers and end users. In either case, there is no limit to the number of plans that may be created or used with Complan.

Complan runs on Windows 10/11.
