TORONTO, ONTARIO, March 16th, 2021 – Kepler Communications Inc. (“Kepler”) released to the public a bespoke software package it has developed to simulate radio frequency interference between satellite networks. The software – written entirely in Python – is being distributed under an open-source license, free to use and edit by the public. With the release, Kepler seeks to improve access to valuable simulation tools that are used to assess the impacts of space-based networks on the interference environment.

Kepler believes its release represents the first open-source publication of this kind of software. Existing solutions for simulating satellite interference are commercial-only, closed-source, and often prohibitively expensive. The contribution of technical expertise and features will improve the ability for satellite operators of all shapes and sizes to assess the impacts of their own networks on those of their peers, and vice versa.

Nicholas Spina, Director of Regulatory Affairs at Kepler Communications said of the software, “Interference analysis is something that all satellite companies have to tackle, and despite there being packages available for purchase, we have seen that most operators either supplement the tools with in-house developed code or don’t have access to anything and may simply outsource the problem. In an effort to harmonize our industry and democratize access to fundamental tools, I am pleased to announce this as the beginning of a series of projects that Kepler will be open sourcing. Our hope is that the Kepler Open-Source Interference Analysis (KOSIA) tool will help accelerate future developments by providing a foundation that other operators and organizations can both build upon and rely on.”

The software is available on Kepler’s GitHub (


Kepler is a satellite telecommunications provider based in Canada, backed by Costanoa Ventures, IA Ventures and other leading investors. Kepler’s mission is to connect people and things Everywhere, on earth and beyond. To this end, Kepler will build an in-space telecommunications network through an incremental deployment of products and technologies. The first to launch and operate a Ku-band satellite service in Low Earth Orbit, Kepler has expanded its capabilities with the successful commissioning of a cubesat production facility at their Toronto headquarters, from which the GEN 1 satellites are being delivered.
