Celestra Space Documentation

Start building with real space software in 5 minutes

Quickstart

This document outlines how to interact with the Celestra Space API via HTTPS POST JSON RPC.

HTTPS-POST RPC

Celestra Space provides a robust and versatile API designed to cater to diverse application needs, leveraging the efficiency and structure of both JSON and Protocol Buffers (Protobuf) for data serialization. This document outlines how to interact with the Celestras Space API via HTTPS POST Remote Procedure Calls (RPC).

Data Serialization

Celestra Space is designed to empower users with robust data handling and analysis capabilities, tailored specifically for the complex dynamics of aerospace environments.

The Celestra platform is built with security in mind at every layer

Platform security

StarSign is Celestra Space’s HMAC scheme for authenticating requests. It’s based on industry recommendations for authenticating requests using HMAC.

Signing API Requests

This document provides an overview of request quotas for Celestra Space, including rate limits and in-flight request limits. These quotas are essential to maintain the performance and reliability of our services.

Kepler's Laws describe planetary motion: elliptical orbits, variable orbital speeds, and a relationship between orbital period and distance.

Kepler's Laws

The rocket equation calculates velocity change in rockets, accounting for exhaust velocity, mass ratio, and varying gravity on different bodies.

Rocket Equation

The Vis-Viva Equation calculates orbital velocity in elliptical orbits, balancing kinetic and potential energy, essential for spacecraft maneuver planning.

Vis-Viva Equation

Hohmann Transfers are fuel-efficient orbital maneuvers between two circular orbits, involving specific delta-V calculations and time considerations.

Hohmann Transfer

The thrust equation links rocket engine thrust to exhaust velocity, mass flow rate, exhaust pressure, ambient pressure, and nozzle area.

Thrust Equation

Specific Impulse measures rocket engine efficiency, linking thrust to fuel use, crucial for determining performance and space travel efficiency.

Combustion Chambers

Convolutional coding is a type of error-correcting code that is extensively used in space communications to ensure the reliability of data transmitted across space where signals are prone to interference and degradation.

Convolutional Coding

Signal modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a modulating signal that typically contains information to be transmitted.
