Cascade Designer

Design and simulate your link in minutes. Share your link budgets across your team. Simulate entire trajectories in a single API call. Use vendor-supplied 3D antenna patterns or upload your own.

Cascade Editor

Drag and drop editor. Choose built-in components, or those provided by 3rd party vendors.

Library of generic RF components to build your system design. The Catalog tab has commercially available parts from suppliers such as Plane Wave and Orbital Systems.

This is a commercially available antenna from Plane Wave. We have loaded the 3D antenna pattern from the vendor and look up the gain and axial ratio based on user input angles from boresight

This is a transmitter block, representing a source of RF power

Using an attenuator to model cable loss

Using a gain block to model a power amplifier

Simple free-space path loss model using the Friis equation

The Cascade Array, with configurable modes and bands. Pricing displayed for each configuration

Multiple demodulators are available, this one is for CCSDS modes and computes C/N0, Eb/N0, and margin

Results pane has the power level, noise temperature, and C/N0 at the output of every block

Team Management

API Access

Create a design checkpoint, then run batch analysis to simulate entire mission trajectories in a single API call.

import requests
 
# Analyze your trajectory CSV file with a single API call
response = requests.post(
    "https://cascade-api-url/analyze-timeseries",
    headers={"X-API-Key": "<your api key>"},
    files={"file": open("your/trajectory/data.csv", "rb")},
    data={"cascade_checkpoint_uuid": "<your cascade checkpoint uuid>"}
)
 
# Get your results
results_csv = response.text
