Accelerating the development of space systems

At Sedaro, our mission is to provide intuitive software tools for NewSpace design, analysis, and testing. The NewSpace paradigm represents a fundamental shift away from traditional space engineering processes: the teams are smaller, the risk tolerance is higher, and the budgets and schedules are more aggressive. We are responding to this shift with tools that aim to minimize the budget, schedule, and specialized expertise required for mission success.

Introducing Sedaro Satellite

An Intuitive, Cloud-Based Satellite Mission Design Platform

Satellite design tools to fit the rapid, low-cost NewSpace paradigm

Focused Scope

Existing satellite mission design and engineering tools have complex user interfaces and workflows. As a result, these tools require significant experience and training in order to be used effectively. By focusing on most, but not all space missions, Sedaro Satellite is able to provide simplified, streamlined interfaces and workflows. This enables non-experts to rapidly generate accurate results and optimized designs.

Modern User Interfaces

With clean aesthetics and intuitive workflows, Sedaro Satellite aims to lead a shift away from the complicated, expert-only tools that are currently the norm in satellite mission design and engineering.

Cloud-Based Architecture

Sedaro Satellite is a cloud-based software-as-a-service (SaaS) application, hosted on ITAR-compliant AWS servers and accessible via a web browser. This allows for constant improvement, practically unlimited computing resources, and streamlined licensing and trials.

Modular Structure & Licensing

Sedaro Satellite employs a flexible, subscription-based pricing model with a base offering licensed annually and all independent, task-specific modules licensed quarterly.

NASA phase I SBIR win enabling model based systems engineering with sedaro satellite

June 30, 2020

Sedaro Technologies is pleased to announce that its NASA Phase I SBIR proposal titled “Enabling Model-Based Systems Engineering with Sedaro Satellite” has been selected for contract negotiation. Sedaro Satellite simulations are run in the cloud, utilizing practically unlimited computing resources to rapidly populate trade spaces and disseminate results. With the intention of further leveraging this capability and streamlining integration into aerospace MBSE workflows, Sedaro Technologies plans to upgrade Sedaro Satellite to enable the import, export, and use of SysML models within the platform. We are excited for this new opportunity and appreciate NASA’s support of Sedaro Satellite!

June 23, 2020

Sedaro invites prospective users to participate in the Mission Designer beta release! This is an important next-step towards the debut of the first two Sedaro Satellite modules: Mission Designer and Energy Balance, planned for August 2020. Submit your email before July 10th to be considered for free, early access to this innovative satellite mission design tool.
